How to ferment and granulate manure with organic fertilizer crusher?

Granulation is the most important link in the organic fertilizer production line. If the organic fertilizer is made into granules, it must be a manure fermentation compost crusher, organic fertilizer granulator, mixer and other equipment. At present, there are several types of organic fertilizer granulation equipment on the market, including disc granulator, flat die granulator, rotary drum granulator, roller extrusion granulator, organic fertilizer granulator. The granulation is mainly based on several methods such as stirring granulation, extrusion granulation and spray drying granulation.

There are two steps in the process of organic fertilizer: pre fermentation and treatment part and deep processing granulation part. It needs fermentation compost turning machine, organic fertilizer crusher, drum screening machine, horizontal mixer, organic fertilizer granulator, rotary dryer, drum cooler, screening machine, coating machine, packaging machine, conveyor and other equipment.
The function of organic fertilizer crusher is to pulverize the compost. It is helpful for granulation. There are still several advantages after crushing organic fertilizer with cow manure grinder and then making it into particle size and shape.
1.The first is to make the land easier to digest, so that organic fertilizer can be quickly integrated into the land.
2.The second is to make the nutrient distribution of organic fertilizer even.
3.The third is the convenience of transportation, so that we can directly put them into bags for transportation.
4.Fourth, the storage is convenient. We can put it in the warehouse after air drying, and we don’t have to worry about the deterioration or decay of organic fertilizer.

How to process top dressing with organic fertilizer production line

Organic fertilizer is not only an ideal base fertilizer, but also as topdressing. It is the main fertilizer variety to provide nutrients during crop growth. Attention should be paid to the following matters when organic fertilizer is used as topdressing:

Early application

Organic fertilizer contains available nutrients, but the quantity is limited. It needs a certain process to release a large amount of slow-acting nutrients. Organic fertilizer should be used as topdressing a few days in advance.
Top application of high quality organic fertilizer
During the rapid growth of crops, a large amount of nutrients such as nitrogen and potassium are needed. Generally, the content of nitrogen and potassium nutrients in organic fertilizers is not high. In order to ensure the nutrient requirements of the rapid growth of crops, high-quality organic fertilizers with higher nitrogen and potassium nutrients should be selected . The rotary drum granulator mixes raw materials containing different nutrients of NPK with organic matter to make high-nutrient organic fertilizer.

Make reasonable distribution proportion of base fertilizer and topdressing fertilizer
When the soil temperature is low, the microbial activity is weak and the nutrient release of organic fertilizer is slow, so most of the applied amount can be used as base fertilizer. However, when the soil temperature is high, the microbial decomposition ability is strong. If the amount of base fertilizer is too much, the fertilizer will be decomposed by microorganism before planting, and the fertilizer effect will be released immediately after planting, which may cause the crop to grow too long. Therefore, in order to cultivate crops under high temperature conditions, the application amount of base fertilizer should be reduced and the amount of topdressing should be increased.
Proper amount of seedling
The nutrient requirement of crop seedlings is small, but the lack of nutrients can not form strong seedlings, which is not conducive to transplanting and future crop growth. Fully decomposed organic fertilizer, processed by organic fertilizer granulator machine, can release nutrients evenly and completely. It is an ideal fertilizer for seedling.


The organic fertilizer production line can directly turn fertilizer into treasure and produce organic fertilizer which has a lot of significance for agriculture. The pollution material is directly used as processing data. If the pollution source does not exist, these pollution problems are also dealt with.

Use organic fertilizer production line to produce fertilizer and develop organic agriculture

In China, people’s living standards have been continuously improved, and the problem of food and clothing has been basically solved. High-yield and high-quality agricultural products and hygienic and healthy food have become the urgent needs of the current society and agricultural production.

China’s use of chemical fertilizer ranks first in the world, and the excessive use of chemical fertilizer leads to the decline of the quality of ecological factors in agricultural production. In China, the actual utilization rate of chemical fertilizer is less than 30%. The intensification of excessive use of chemical fertilizer leads to a large reduction of beneficial bacteria in the soil, a decline in soil quality, a reduction in self-purification ability, affecting the yield and quality of crops, endangering human health, and even the risk of environmental retaliation. Hazards of using fertilizer:

1、 Reduce crop productivity

As a result, the soil is hardened, the content of soil organic matter is reduced, the fertility is decreased, and the living space and quantity of beneficial microorganisms in the soil are reduced. The disease resistance, cold resistance, drought resistance and lodging resistance of crops are weakened, and the occurrence of diseases and insect pests is becoming more and more serious, leading to the decline of crop quality and yield.

2、 Aggravate environmental pollution. If too much fertilizer exceeds the soil’s retention capacity, it will flow into the surrounding water, resulting in agricultural water pollution, eutrophication of water body, algae breeding, and then damage the water environment. According to statistics, more than 10 million tons of nitrogen are lost out of farmland every year due to unreasonable fertilization in China, resulting in a direct economic loss of about 30 billion yuan. Excessive fertilizer will also seep into the shallow groundwater within 20 meters, making the nitrate content of groundwater increase.

3、 Waste a lot of scarce resources. If the wasted chemical fertilizer can be saved, the energy shortage in China will be alleviated. In 2004 alone, China’s fertilizer production consumed about 100 million tons of standard coal, more than 5% of the national energy consumption. In addition, China’s fertilizer production consumes more than 100 million tons of high-grade phosphate ore every year, and phosphate ore has been listed in the list of scarce resources by the Ministry of Land and Resources after 2010; Fertilizer production also consumes 72% of China’s sulfur resources.

The organic fertilizer production line uses modern microbial technology, mainly livestock and poultry excrement, and bran, peanut shell powder, crop straw and other auxiliary materials as carriers. The bacteria and livestock and poultry excrement are fully mixed by mixing method, so that the microbial bacteria are connected to the livestock and poultry excrement, including dehydrator, fermentation turner, semi-wet material crusher, horizontal mixer, granulator, dryer, cooler, drum screening machine, film coating machine The bio-organic fertilizer produced by packaging equipment, belt conveyor and other equipment after a series of harmless treatment such as rapid heating, fermentation, decomposition and deodorization.

Working process of circular granulator in organic fertilizer production line

The equipment used in organic fertilizer production line for polishing round particles is called organic fertilizer particle polishing machine. The organic fertilizer granule polishing machine is a new type of ball shaping equipment which is improved on the basis of the traditional granulation. The new round throwing machine realizes continuous feeding and discharging, and improves production efficiency.

The columnar granular materials rotate with the shaping disc under the action of friction force. The shaping cylinder is fixed. In this way, the columnar materials in the shaping cylinder rotate in a twist like manner along the edge of the shaping disc and the wall of the shaping cylinder under the action of centrifugal force. When the continuous feeding reaches the first stage of the whole plate, the discharging height of the discharging port automatically enters into the next stage shaping plate.

The material coming out of the primary shaping disc has changed from columnar to irregular round granular. After the same movement of the lower-level plastic plate, after coming out of the multi-level plastic plate, it becomes a uniform and bright round granular organic fertilizer (higher moisture content). Then transport to the next drying section. The ball shaping machine is used in the production of organic fertilizer. The particles produced by rotary drum granulator and disc granulator are spherical and do not need to be rounded.

Price of sheep manure organic fertilizer granulator

The output specifications are different, and the fertilizer granulator machine price is different. Our sheep manure organic fertilizer granulating equipment is used to granulate various organic substances after fermentation. The raw materials do not need to be crushed and dried before granulation. Processed spherical particles can save a lot of energy and break through the conventional organic granulation process.

Characteristics of organic fertilizer granulator for sheep manure

1. The organic matter after fermentation does not need to be dried, and the moisture content of raw material can be in the range of 20-40%.
2. The particles produced are spherical.
3. With high content of organic matter, granulation of pure organic matter can be realized.
4. Due to the fact that organic particles can be inlaid with each other under a certain force, no binder is needed in granulation.
5. The granules are solid and can be screened after granulation, which reduces the drying energy consumption of the fertilizer production line.

Automatic feeding silo of organic fertilizer production line can improve the feeding efficiency

With the modernization of breeding plants, the treatment of livestock manure is becoming more and more diversified. Manure is treated by fertilizer production line in industrialization, and the manure is directly used as high-quality organic fertilizer after professional treatment. Fertilizer granulator, compost turner and other equipment ferment livestock manure into organic fertilizer, which not only protects the environment, but also improves the soil, increases soil fertility, increases crop yield, reduces the amount of chemical fertilizer, and achieves multiple effects with one stroke.

The automatic feeding bin is the pre-treatment equipment in the organic fertilizer production line. The machine is mainly used to shovel materials into the feeding bin by forklift silo, which can save manpower, reduce labor intensity and improve work efficiency. The mixing shaft of the silo will transfer the materials into the lower conveyor belt, and then the materials will be evenly transported to the granulation equipment or crushing equipment by the conveyor. On the one hand, human beings can be freed from the monotonous and complicated physical labor. On the other hand, only the realization of industrial full-automatic production is the solution to improve the production efficiency.
Automatic feeding silo of organic fertilizer production line
One of the key technologies to improve production efficiency in the machining process is to realize the function of automatic loading and unloading, and the automatic loading and unloading device must meet the process of automatically operating or controlling according to the prescribed procedures or instructions without human intervention. Its goal is “stable, accurate and fast”, which means that the automatic loading and unloading device must meet the precise positional relationship between the processed parts in the loading and unloading device and the loading and unloading manipulators, so as to ensure the loading and unloading of the manipulators. Accurate and fast unloading.
After being transported by the loading car, the raw materials are further granulated by the rotary drum granulator, and finally dried and cooled. After screening, the high-quality organic fertilizer is obtained

The chicken farm can build an organic fertilizer production line to increase income

hicken dung can be used as organic fertilizer in three ways: directly as organic fertilizer after drying, or as raw material for organic-inorganic compound fertilizer production. It can be fermented by compost, or it can be fermented by biogas and then mixed with other organic materials for compost fermentation, and then directly used as organic fertilizer or as raw materials for other organic fertilizers.

  1. The chicken manureorganic fertilizer equipmentdoes not contain any chemical components. Due to the poor digestion ability of the chicken, only 25% of the nutrient components can be consumed, while the other 75% of the nutrient components in the feed are discharged with the manure, so that the dry product contains nitrogen, phosphorus, potassium, organic matter, amino acid, protein and other components.
  2. The main substance in chicken manure is organic matter, which increases the content of organic matter in soil. Organic matter can improve soil physical, chemical and biological properties, ripen the soil, and improve soil fertility. The proverbs of “the ground depends on dung, and the seedlings depend on dung” in rural areas of China, to a large extent, reflect the role of chicken manure in improving soil.
  3. Chicken manure not only increases many organic colloids, but also decomposes and converts many organic substances into organic colloids through the action of microorganisms, which greatly increases the adsorption surface of the soil, and produces a lot of sticky substances, making the soil particles cemented into stable aggregate structure, improving the performance of soil water conservation, fertilizer conservation and air permeability, as well as the ability to regulate soil temperature.
  4. Chicken manure can also make the microorganisms in the soil multiply, especially many beneficial microorganisms, such as nitrogen-fixing bacteria, ammonifying bacteria, cellulose decomposing bacteria, nitrifying bacteria, etc. There are various active enzymes secreted by the digestive tract of animals and various enzymes produced by microorganisms in chicken dung. After these substances are applied to the soil, the enzyme activity of the soil can be greatly improved.

The reason that many organisations will build a complete organic production plant is caused by the sheer number of manure that they could collect in the animals on their own property. You can find farms who have hundreds and hundreds of chickens, and similar amounts of cows, all of which are producing waste materials daily. Rather than letting this simply enter in the ground through natural decomposition and percolation processes, you are able to collect it, process it, and store it for future use. This is certainly all done inside of that plant that will possess the machinery necessary to do these kinds of conversions.

Fertilizer machinery manufacturers guide how to select compound fertilizer production lines

How can agricultural producers avoid inferior fertilizer and buy high quality compound fertilizer? Fertilizer granulator manufacturers guide you in the following ways.

1. Look
The compound fertilizer is processed by the rotary drum granulator. Generally, the granules are the same, without large lumps, and less powder. Small red potash fertilizer particles or white urea particles can be seen. For compound fertilizers with high nitrogen content, many attached white fine crystals can be seen on the surface of fertilizer grains after a period of storage. Inferior compound fertilizer does not have these phenomena.
2. Rub
Knead the compound fertilizer with your hands, leaving a layer of gray powder on your hands, and the sticky compound fertilizer. It is also good to break its particles and to see fine white crystals. Inferior compound fertilizers are mostly gray-black powder, without stickiness, and no white crystals in the particles.

3. Burn

Take a little compound fertilizer and put it on the iron sheet and burn it in the open fire. If there is a smell of ammonia, it means that it contains nitrogen, and purple flame means that it contains potassium. The more ammonia flavor, the longer the purple flame is. On the contrary, it is inferior.
4. Dissolving
Compound fertilizer will be dissolved in water, even if there is a small amount of precipitation, it is also smaller. Poor quality compound fertilizer is rough and hard, and difficult to dissolve in water.
5. Smell
Compound fertilizer generally has no peculiar smell (except for organic-inorganic compound fertilizer). If it has peculiar smell, it indicates that it contains ammonium bicarbonate or toxic substances such as Trichloroacetaldehyde (acid).

Advantages of chicken manure in composting and fermenting fertilizer using organic fertilizer production line

1. Start fermentation quickly. Generally in summer, the composting time for chicken manure compost treated by a professional compost turning machine to reach the harmless index is about 20 days, and it usually takes about 60 days for natural fermentation to reach this index. Mainly because of the growth and reproduction of microorganisms, the materials in the materials are fermented and degraded, shortening the time for compost to reach the high temperature stage, and prolonging the high temperature period. In winter, because the temperature is too low, it is difficult to start fermentation. You can add starter microorganisms to the chicken manure to quickly start the chicken manure fermentation.

2. Eliminate pathogenic microorganisms. In the process of adding microbial agents to treat chicken manure with an organic fertilizer turning machine, the compost temperature can reach 65℃~70℃ or even higher. The high temperature not only makes the chicken manure and other materials decompose quickly, but more importantly, it can effectively kill Inactivate pathogenic microorganisms or viruses, among which the stack temperature of 50℃~70℃, lasts for 6~7 days, to the eggs and pathogenic bacteria. It can achieve a very good lethal effect, such as avian influenza virus, which can be killed in a few minutes at a high temperature of 60℃~70℃.
3. Remove odor. Chicken manure composting fermentation can effectively remove malodorous gas. This is mainly because microorganisms can decompose non-nitrogen and sulfur-free organic substances such as phenol, carboxylic acid, formaldehyde, etc. into CO2 and H20; ammoniated nitrogen-containing organic substances into NH3, which can be oxidized by nitrosating bacteria to NO2- , And then further oxidized to N03- by nitrifying bacteria; sulfur-containing malodorous substances are decomposed by microorganisms to release H2S, and are oxidized by sulfur oxidizing bacteria to sulfuric acid, so that pollutants can be removed.
4.Increase fertilizer efficiency. Microorganisms can decompose starch, lipids, hemicellulose, protein and other easily decomposed substances in chicken manure, as well as some cellulose and a small amount of lignin. Some of them are converted into water-soluble carbon and nitrogen compounds. At the same time, some carbon and nitrogen sources used by microorganisms are gradually decomposed and released with the death of microorganisms. Therefore, it can increase the content of water-soluble carbon and nitrogen in feces. Compared with the natural fermentation of chicken manure, the various enzymes produced during composting can catalyze the rapid transformation of organic matter into humic state, and the treated compost can synthesize more humic carbon and nitrogen in the same time. The compost after fermentation can be used as raw material, mixed with other NPK fertilizers, and processed by rotary drum granulator.
5.Improve crop safety. Uric acid and NH4 + – n are the main substances that affect the normal growth of crops in chicken manure. Chicken manure composting can promote the transformation of nitrogen in compost to protein nitrogen and NH3 + – N, reduce the accumulation of NH4 + – N, and quickly eliminate or reduce the substances that cause crop growth obstacles.
6.It can be made into roughage for other animals. Crude protein accounts for 31% – 33% of the dry matter of chicken manure, and more than half of them are non protein nitrogen such as uric acid, urea, creatine and ammonia, and the crude fiber contained in chicken manure and a large amount of crude fiber in bedding grass. Therefore, chicken manure is a good feed for raising livestock, poultry and fish. However, raw chicken manure contains parasitic eggs and some toxic substances and bacteria, which can not be directly fed with raw chicken manure. Microbial agents must be added to chicken manure for high temperature fermentation treatment, so that it can be processed into non-toxic and nutritious feed by fertilizer granulator.

Production cost and benefit analysis of equipment production line with an annual output of 5000 tons of organic fertilizer

Nowadays, organic fertilizer has been loved by cash crop growers all over the country, and plays an indispensable role. Bioorganic fertilizer contains a large amount of organic matter, which is an important source of organic matter in soil. It can improve soil, improve soil fertility, turn lean soil into fertile soil, and turn bad soil into good soil. Because soil organic matter forms humus through the action of microorganism and physical chemistry, it can promote the formation of soil water-stable aggregate structure, make cohesive soil loose and easy to cultivate, and sandy soil become structured.

Taking livestock and poultry manure as an example, the annual output of 5000 tons of granular organic fertilizer equipment investment, production cost and benefit analysis.

Input cost of organic fertilizer production line:

  1. Plant: at least 500 square meters, including fermentation tank area, raw material manure stacking area, fermented organic fertilizer processing and packaging area, finished organic fertilizer stacking area, etc. The plant does not need good materials, but its height is at least 5 meters, and the construction cost per square meter is about 350 yuan.
  2. Fermentation of livestock and poultry excrement: build a relatively large excrement treatment station in a large-scale (one machine with multiple tanks) centralized breeding area. The daily treatment of livestock and poultry excrement is more than 12 tons, with a 3M span trough tipper, and the unit price is 26000 yuan/set; Build a 300-500 square meter transparent greenhouse, with several fermentation tanks built in the greenhouse (the cost depends on the local actual situation due to different materials).
  3. Tipper: fixed rail type tipper: the price of the tipper is about 15-200 yuan, and the cost of the line, rail and installation is about 30000 yuan. Two fermentation tanks share one tipper (including exchange equipment); If a walking tipping machine is used, the price of each machine is 6-150000 yuan, but it can be directly stacked on the ground for fermentation without building a fermentation tank.
  4. Forklift: This is a necessary equipment to improve efficiency. Small-sized forklifts are generally priced at 6-150000 yuan. You can buy second-hand ones, generally around 30000 yuan; At present, there are also walkable tipping machines+forklifts in one, with a price of 55-1200 (different specifications).
  5. Organic fertilizer crusher: the fermented organic fertilizer is crushed to more than 40 meshes, and the finer the crushed organic fertilizer is, the more beautiful the later granulation is. The specifications with the price of 4500-200000 yuan are determined according to different output.
  6. Conveyor: configure belt conveyor, bucket elevator or screw conveyor according to the actual needs of customers. According to the length of transmission, a production line generally needs two conveyor belts of about 10 meters, and the price of each belt is between 15000 and 25000 yuan.
  7. The packaging machine is mainly composed of material inlet, feeding mechanism (gate), weighing bucket, bag clamping mechanism, frame, suction port, pneumatic system, sensor, control box, conveying and sewing mechanism, etc.
  8. Multi-element organic fertilizer formula batching machine (equipment price is between 11000 and 18000 yuan): adjust the content of nitrogen, phosphorus, potassium, humus and organic matter of powdered organic fertilizer according to different crop requirements.
  9. Formula mixer (equipment price is between 21000 yuan and 38000 yuan): fully mix and evenly mix the prepared formula elements.
  10. Organic fertilizer granulator: the prepared fertilizer elements are used to agglomerate the powder into particles under the mechanical action by centrifugal granulation.
  11. Dryer (equipment price is 28-1800 yuan): dry the prepared particles for storage.
  12. Cooler (the equipment price is about 3.5 yuan): quickly cool the dried fertilizer particles and facilitate bagging.
  13. Screening machine (equipment price is about 5-2000 yuan): classify the size of fertilizer particles, and bag them in batches according to the size of the particles.
  14. Fertilizer granule coating machine (equipment price is about 20000 yuan): Apply a layer of non-caking agent on the surface of the finished granules to make the fertilizer granules not stick.

Calculation of production cost of organic fertilizer (organic fertilizer per ton of product):

  1. Daily consumption of fresh livestock and poultry manure: daily output of 12 tons × 2.7 m3/t × 15 yuan/square meter=486 yuan (excluding freight), the subtotal is 40.6 yuan per ton.
  2. The annual production of 5000 tons of organic fertilizer requires 100 tons of dry straw powder. (For summer use, purchased from outside) 170 yuan per ton, totaling 17000 yuan, with a subtotal of 3.4 yuan per ton.
  3. The dosage of bacteria is 1/15000, 2.16 kg per day × 100 yuan=216 yuan, subtotal 18 yuan per ton.
  4. The subtotal of freight is 20 yuan per ton. (transported from the breeding farm to the packaging workshop)
  5. The depreciation cost of facilities and equipment is calculated as per five years (equipment and facilities, calculated as per 200000 yuan, is about 40000 yuan per year, with a subtotal of 8 yuan per ton).
  6. Total wages. There are 5 workers, and the daily wage of each person is 100 yuan. The total daily wage is 500 yuan/12 tons=41.6 yuan/t, and the subtotal of each ton is 41.6 yuan.
  7. Daily power consumption: 80 kWh × 10 hours/day × 0.6 yuan/degree=480 yuan, with a subtotal of 48 yuan per ton.

The total production cost per ton of granular pure organic fertilizer (with nutrient content of more than 9% and organic matter of about 75%) is about 180.0 yuan/ton.

Analysis of organic fertilizer sales income

The production cost per ton of pure organic fertilizer produced by fermentation mode is about 180.0 yuan/ton. It is adjusted according to the national organic fertilizer standard, plus the warehousing cost of packaging bags, etc. of 50 yuan/t. It is sold at the current market price of 600 yuan per ton. The gross profit per ton is 270 yuan/ton. The net profit is calculated at 50 yuan, excluding the intermediary and transportation fees. The annual sales of 5000 tons * 270 yuan/ton can earn 1.35 million yuan.

The above data are for reference only, mainly because the prices of facilities and equipment produced by different factories are different, and the costs of plant construction and labor costs are different in different places. In addition, the above is the investment required for one production of organic fertilizer. If multiple organic fertilizer production lines are built, they can be calculated by superposition, but some equipment and facilities can be shared. Therefore, the more production lines, the lower the average investment.
