Reasonable ratio of raw materials is the basis to improve the ball formation rate

Single chemical fertilizer can not meet the needs of various nutrients of plants. NPK fertilizer production line mixes and granulates different nutrients to improve fertilizer efficiency. So how to improve the pelletizing rate of fertilizer?

1. Reasonable match of fineness of raw materials. According to our experience, the fineness of the whole raw material should be matched as follows: about 30% – 40% of the raw materials with 100-60 mesh, about 35% of the raw materials with 60 mesh to 1.00mm diameter, and about 25% – 30% of the small particles with 1.00-2.00mm diameter. The higher the fineness of the material, the better the viscosity, and the higher the surface finish of the granulated particles. However, in the production process, the proportion of high fineness materials is too high, and it is easy to cause the bad problems such as too large particles, irregular particles and material wall sticking due to the good viscosity.

2. The reasonable collocation of cohesive material and dispersive material. In the production process formula, the proportion of viscous raw materials is high, the organic fertilizer granulator is easy to form balls, the proportion of dispersive raw materials is high, and there are more fine powders. In the conventional formula, the proportion of low concentration compound fertilizer viscosity raw material is 45% – 50%, and the proportion of high concentration compound fertilizer viscosity raw material is 35% – 40%. At the same time, it should be combined with material fineness. With bad matching, there will be no fine powder, no particles, particles are not round, easy to get big balls and other problems in the production process.

3. The chemical reaction between materials should be considered when formulating. After the formulation of some materials, free water will be precipitated during the production process, which will cause the liquid phase of the material to exceed the standard and cannot be produced normally. After matching, some raw materials will greatly reduce the critical relative humidity of the mixture. During the process of organic fertilizer production equipment, due to the large amount of moisture absorption Unable to produce normally. Therefore, the chemical reaction between the materials must be considered when formulating to achieve a reasonable match between the materials.

4. Comprehensive water content of the material after mixing. The water content of the raw materials directly affects the pelletizing effect of the disc granulator machine. Some materials are stirred into mud without steam and water in the production, resulting in the failure of normal production. Therefore, keeping a low water content of the material is conducive to the addition of steam in the granulation, to the improvement of the temperature and viscosity of the material, so as to improve the compatibility between the materials and the balling rate.

Cassava residue fermentation and feeding method

What is the difference between cassava residue fermented organic fertilizer and non fermented organic fertilizer? There are many disadvantages in the traditional cassava residue fermentation: not only the fermentation time is long, the labor intensity of the fermentation process is large, it takes a lot of energy to stir a ton of cassava residue and other mixtures, but also the nutrition of the cassava residue treated by this method can not be completely released and improved. So what are the advantages of using organic fertilizer production equipment to process cassava residue?

Fermentation of cassava dregs with compost turner

Mix the starter with corn flour (wheat flour, dry potato flour, cassava flour and sorghum flour, as much as possible), stir evenly, add a large amount of cassava residue, and a small amount of brown sugar. The water content shall be controlled within 60% (the standard for the water content of roughage starter is: grasp a handful of feed by hand, and hold it gently, a small amount of water will drip out, or there will be water between fingers. The raw materials are piled up for fermentation, and then the raw materials are put into the fermentation tank for fermentation, and a layer of textile bag is added on the top to protect the plastic film. Generally, it needs to be fermented for 10-15 days, with sweet wine and mellow aroma, which can be used to feed pigs.

In the fermentation process, the use of compost turning machine to deal with the barber ferment, the efficiency of mechanized tossing is more than three times that of traditional fermentation and cooking. High temperature compost can rapidly degrade its crude fiber, improve nutrition and digestibility, greatly improve the use of cassava residue in feeding, and reduce feed cost to the maximum extent.

Feeding method of cassava residue organic fertilizer

Feed pigs with 30% fermented cassava residue and 70% mixed feed. Without mixing materials, corn flour, wheat bran, peanut bran or soybean meal, bone meal, trace elements and other raw materials are used to prepare the mixed feed. When preparing, it should be noted that energy feed accounts for 70% and protein feed accounts for 30%, and it can be fed as a mixed feed. Because the mixture is dry, and the fermented cassava residue is a wet material with a moisture content of about 70%, when preparing the mixture with the cassava residue fermentation material, a 30% ratio of cassava residue is recommended for practical use. The weight, that is, the total weight of the formulated feed is 50 kg, which is the weight of the dry feed. Fermented cassava dregs account for 30% of the total, and the actual amount formulated into the feed is 30 kg.

Since its establishment for many years, Tianci fertilizer machine enterprise has focused on fertilizer manufacturing equipment, crusher, screening machine, dryer, organic fertilizer granulator, packaging machine, etc. we always put the interests of customers first, and insist on transferring good compost fermentation equipment to more farmers.

Application of poultry manure organic fertilizer production line in Xinjiang

The fertilizer production still needs to be operated by professional npk production line. The chicken manure without fermentation and ripening is used as organic fertilizer after drying, which will ferment and ripen in natural state, which may harm crops and is not conducive to crop growth. Chicken manure into organic fertilizer requires fermentation, ripening, granulation and drying process. After high temperature decomposition, it does not contain harmful bacteria and insect eggs, which avoids the disadvantages of farm manure, such as easy to burn seedlings, odor, and many diseases and insect pests.

Treatment mode of small fertilizer production line

First of all, the wheat straw is mechanically crushed by a pulverizer, then poured into the fermentation tank, mixed with water, added with sludge, and then added with chicken manure, sheep manure, rabbit manure, urea, etc. The raw material of organic fertilizer begins to ferment and decompose. After about 15 days of fermentation, the material is processed by the compost turning machine, so that the straw can rot completely and release the fertility, which is absorbed by the sludge, and the fertility of other organic fertilizers is absorbed at the same time.

Then the material is crushed by the semi wet material pulverizer and sent to the drum screening machine for screening. It can be used after 5 days of secondary fermentation. After crushing and screening, the materials can be granulated by rotary drum granulator or other granulating equipment, the appearance of particles is more beautiful and the granulation rate is higher.

The configuration of small organic fertilizer production line directly affects the benefit. Therefore, for fertilizer equipment, we can not blindly choose, to choose the appropriate configuration of fertilizer production line. Huaqiang fertilizer machine price is low, and It has a good quality, which is the first choice for small organic and npk fertilizer plants. The conveying equipment of fertilizer production line adopts belt conveyor and large angle belt conveyor, which not only ensures the smooth transportation system, but also protects the particles, reduces the height of the plant and reduces the infrastructure construction.

Controlling the rotary drum granulator to improve the particle roundness

The time and frequency of material rolling in the rotary drum granulator are the primary factors to determine the pelletizing rate and particle roundness. The roundness of granular product in fertilizer production line can be improved by controlling the drum granulator.

rotary drum granulator
rotary drum granulator

Production principle of rotary drum granulator

Materials rely on surface tension, proper amount of liquid phase, extrusion force generated by rolling between materials, and correct movement direction of materials in the granulator, with small particles as the core, they absorb and adhere to each other and form balls in rolling. In a certain period of time, the higher the rolling frequency is, the higher the spheroidization rate is, and the rounder the particles are.

In the process of production, we have encountered two kinds of situations due to the different friction between materials and the wall of granulator.
1. The internal surface finish of granulator is large, so that the friction force between material and cylinder wall is reduced, and the upward movement force of material is weakened. If the material does not roll, it will not produce particles. In view of this situation, we can solve this problem by adjusting the speed of the granulator and installing a small plate inside.
2. The material in the drum granulator is severely stuck to the wall, and the friction between the material in the granulator and the wall of the barrel is increased, which raises the material in the machine too high, causing the material to fall from the top, so that the formed particles are not Rounding and excessive large particles, we think there are two reasons for this situation: on the one hand, the material is caused by too much viscous material, in this case, we change the formula of the npk production line to reduce the amount of viscous material; on the other hand , The inside of the granulator is not smooth. In this case, we change the internal material to increase the smoothness of the granulator.

On the other hand, we should also control the reasonable amount of material returned to the whole fertilizer production line. The process of rotary drum steam granulation is different from that of general fertilizer granulator, the relative pelletizing rate is lower, and the amount of returned material is higher. The amount of returned material directly affects the output and quality. The product has less particles, more powder and larger amount of return material, which directly affects the output. Large particles return more materials, directly affect the smoothness and roundness of the product.

Several basic granulation methods of NPK fertilizer

Mixing granulation of different NPK fertilizers is the core of compound fertilizer processing. Fertilizer production line generally uses the following methods to granulate:

1. Extrusion granulation is a method of making dry powder or wet powder containing binder into cylindrical, spherical or sheet shape by mechanical processing such as extrusion, roller extrusion or pressing. The technology of dry granulation is used in the flat die pellet mill, the ring die pelleting machine and the double roller granulator.

2. Agglomerating granulation, which is under the action of rotation, vibration, agitation and so on, makes the wet powder in motion agglomerate. Or use the fluidized bed to make the material obtain the cohesive force by supplying the spray liquid binder) so as to grow into the appropriate particles. This method is used in disc granulator and rotary drum granulator.

3. Crushing granulation, which is to crush the block material into particles of appropriate size.

4. Melt granulation, which is a method of cooling and hardening molten liquid for granulation.

5. Spray granulation. It is a method of directly forming granules after concentrating the solid in the liquid.

6. The method of crystallization and granulation in liquid phase is to make materials precipitate and crystallize in liquid phase, at the same time, agglomerate into spherical particles by the action of liquid bridging agent and agitation. This technology is widely used in pharmaceutical industry. Because the shape of the particles is spherical, it is also called spherulite granulation, which is called spherulite granulation for short. Spherulite is a kind of spherical particle formed by the crystallization and aggregation of pure materials. It has good fluidity, filling and compression formability. In recent years, the technology has been successfully applied to functional pellets.

15t/h sulfur-coated urea fertilizer production process and analysis

Advantages of sulphur-coated urea fertilizer

Sulfur coated urea, also known as sulfur coated urea, sulfur coated urea, controlled-release urea, is a new type of slow-release fertilizer. Similar to NPK granular fertilizer processed by rotary drum granulator, the product has the function of slow release and controlling fertilizer effect. According to different growth stages of crops, releasing nutrients according to nutrient requirements can reduce nutrient loss, improve fertilizer utilization, save resources and protect the environment. This product is not only an ecological and green agricultural product, but also a new type of product to replace common urea in the future.
1. The empty shell of sulfur fertilizer can store water. Through the soil, it can drive away the sterilization. Sulfur fertilizer and its compounds have been successfully applied to the improvement of saline alkali soil.
2. The product can not only supply sulfur to the soil, improve the yield of crops, but also improve the quality of crops to a certain extent.
3. Applying sulphur urea once can meet the needs of each growth stage of crops, which can greatly reduce the input of labor force.

A large number of studies show that most of the effective components of conventional chemical fertilizer are lost due to the volatilization and decomposition of drenching culture, resulting in less than 50% absorption by crops, that is, the utilization rate of conventional chemical fertilizer is less than 50%. Therefore, improving the utilization rate of fertilizer is the main content of fertilizer industry research. China’s research shows that more than 10 million tons of nitrogen are lost out of the world every year due to unreasonable fertilization, with a direct economic loss of over 10 billion yuan. The economic loss caused by the pollution caused by the loss of drainage to the people’s health and the quality of agricultural products is incalculable, with an upward trend in recent years.

Production process of sulfur-coated urea fertilizer

Different from organic fertilizer manufacturing process, sulfur-coated urea is coated with sulfur uniformly on the outside of ordinary urea, and then coated with a small amount of sealant and conditioner containing trace elements on the surface of sulfur. After this product is scattered in the farmland, urea nutrients are slowly released through the sulfur shell for crop absorption and utilization, which plays a role in prolonging fertilizer utilization. Chinese Tianci factory has specially designed a fertilizer production line with an output of 15t/h to process this fertilizer, so that urea can achieve the required fertilizer efficiency.

15t/h sulfur-coated urea fertilizer production process
15t/h sulfur-coated urea fertilizer production process

For general agricultural producers, in order to increase crop yields, the amount of fertilization must be increased accordingly, but when the fertilization reaches a high enough, and resources and the environment does not allow, it should seek to reduce the amount of fertilizer, through the use of new fertilizers. The new fertilizer formula can fully achieve the purpose of increasing production. The compound fertilizer granules and sulfur-coated urea fertilizer made by NPK fertilizer granulator are welcomed by the market.

Organic fertilizer made from waste vegetable leaves in vegetable greenhouses

Vegetable greenhouses will inevitably produce waste vegetable leaves. As the vegetable planting area continues to increase, a large number of stumps and leaves are produced. Every year melons, nightshade fruits, leafy vegetables and other vegetables produce nearly tens of thousands of dead branches and rotten leaves. For a long time, some farmers will randomly discard, let them rot or dry and burn the vegetables, which will cause the spread of pests and pathogens in the soil and air, and bring pollution to the environment. Organic fertilizer made from abandoned vegetable leaves in vegetable greenhouses has been vigorously promoted in the planting industry.

waste vegetable leaves
waste vegetable leaves

The processing technology of the organic fertilizer production line is to use a crusher to crush the collected vegetable leaves, add fermentation bacteria, stack the raw materials at high temperature, and then use a compost turning machine to turn the stack to make it fully rotted.

The crushed stem and leaves can be piled up and fermented at high temperature, and then they can be turned into organic fertilizer for reuse. Let the waste vegetable leaves turn into treasure, and solve a big problem of vegetable greenhouse planting in time. The fermented waste is made into organic fertilizer by the fertilizer granulator, and finally the vegetable leaf organic fertilizer is returned to the field. A large number of organic matter and nutrients promote the growth of vegetables better.

Relying on the technology of the organic fertilizer production line, the vegetable waste in the greenhouse has found a new way of recycling. The production and treatment technology of waste vegetable organic fertilizer has been put into use in many vegetable bases in China. And the use of processed organic fertilizer, vegetables look good, taste better. The implementation of organic fertilizer production line can reduce the environmental pollution and soil structure damage caused by discarded vegetable leaves, and help to enhance the safety of vegetables. Organic fertilizer equipment manufacturers hope that more vegetable bases will use this technology to realize the harmless use of vegetable leaves. We provide organic fertilizer machine, rotary drum granulator, disc granulator machine, organic fertilizer dryer, crusher and other fertilizer equipment.

Points for attention in roller extrusion granulation

Roller press granulator uses physical method to granulation. The whole process has no pollution and no waste. It is a very environment-friendly organic fertilizer machine. The following will lead you to understand the use of double roller extrusion granulator precautions.

Working principle of double roller press granulator

When the roller extrusion pelletizer is working, it is forced to roll the material into shape by two opposite moving roller skins of the granulation machine. Semi circular spherical cavities are regularly distributed on the two cylindrical roller skins. When the roller skin rotates against each other, the two semicircular cavities just form a complete spherical mold, and the materials inside are forced to be extruded into spherical particles. Due to the continuity of extrusion production, the particles and particles are connected together when they are just extruded, forming a cloth full of particles, which needs to be broken up by the crushing roller and divided into small round particles, and then screened from the screen to select the qualified particles.

The use of roller press granulator

When the double roller extrusion pelletizer is producing granular fertilizers, it should be noted that the ball sockets on the two roller skins should be properly positioned. If they are not adjusted in place, they will be misaligned during granulation and cannot produce qualified products. Granular fertilizer. In addition, after the particles are formed, they are released from the ball socket of the roller skin in time, so that uninterrupted production can be realized. If the formed particles are not released in time, complete particles will not be formed, which will affect the npk production line.
