The granulation process of drum granulator in compound fertilizer production line

Compound fertilizer refers to a type of compound fertilizer that is made solely by chemical methods, with at least two of the three nutrients of nitrogen, phosphorus, and potassium indicating their amounts. Compound fertilizers have the advantages of high nutrient content, fewer side components, and good physical properties. They play a very important role in balanced fertilization, improving fertilizer utilization efficiency, and promoting high and stable crop yields. But it also has some drawbacks, such as its nutrient ratio is always fixed, and the types, quantities, and proportions of nutrients required by different soils and crops are diverse.

The process flow of small-scale Organic fertilizer production equipment is as follows: Organic fertilizer raw materials enter the semi wet material grinder for grinding after fermentation, and then add elements such as nitrogen, phosphorus and potassium to make the mineral elements contained meet the required standards, and then there is a mixer for mixing, and then enter the Organic fertilizer granulator for granulation, drying after coming out, screening through the screening machine, packaging qualified products, and returning unqualified products to the Organic fertilizer granulator for granulation.

The drum granulator is a molding machine that can manufacture materials into specific shapes. The drum granulator is one of the key equipment in the compound fertilizer industry, suitable for cold and hot granulation as well as large-scale production of high, medium and low concentration compound fertilizers. The main working method is wet granulation of pellets. By using a certain amount of water or steam, the basic fertilizer is humidified in the cylinder and undergoes a thorough chemical reaction. Under certain liquid phase conditions, with the help of the rotational motion of the cylinder, the material particles are squeezed and agglomerated into balls.

The drum granulator utilizes the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously mix, granulate, spheroidize, and compact fine powder materials in the machine, thus achieving the purpose of granulation. This granulation method results in higher ball forming rate, more beautiful particles, and energy saving.

The drum granulator is particularly suitable for granulating lightweight fine powder materials. The finer the basic particles of fine powder materials, the higher the sphericity of the particles, and the better the ball forming quality. It is generally required that the particle size of the material before granulation should be less than 200 mesh. Typical application materials include chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc.

How to keep the correct temperature when fermenting raw materials in Organic fertilizer composter

The natural composting process of animal manure organic fertilizer can be divided into heating, high temperature and cooling processes. During this process, microorganisms multiply rapidly, decompose organic matters, accumulate a large amount of ammonium nitrogen in the bulk, and make the H value rise, so as to accelerate the volatilization and loss of ammonium nitrogen in the form of gaseous nitrogen. The ammonium nitrogen needs to be fixed into nitrate nitrogen through the transformation of nitrifying bacteria, and nitrifying bacteria are inhibited in the high temperature stage, so The volatilization of nitrogen mostly occurs at high temperature. Therefore, it is necessary to find a balance between the complete maturity of organic materials and the adjustment of pH value by cooling and nitrogen fixation.

Aerobic fermentation is a relatively mature fertilizer production process, which can reach above 50 ℃ in about 20 days, and then keep high temperature for a period of time. Anaerobic fermentation is in a low temperature state, the fermentation time is long, so the fermentation cycle is long, and the cost is increased accordingly.
The intermittent fermentation process is the key point of this experiment, taking into account the advantages of aerobic fermentation and anaerobic fermentation. In the early stage, the temperature is raised rapidly through aerobic fermentation to speed up the fermentation cycle, and in the later stage, keeping anaerobic can reduce the pH of the whole sample pile. The intermittent fermentation technology can be used for the fermentation of organic fertilizer. Judging from the temperature curve, the intermittent fermentation can also make the manure of livestock and poultry fermented in about 50 days.
At the same external room temperature, pig manure, cow manure and chicken manure as raw materials have little effect on the temperature of the whole fermentation process. In the aerobic stage, the maximum temperature of chicken manure and cow manure is slightly higher than that of pig manure, but generally speaking, the composting temperature curves of three different manure sources are similar.
After adding sulfur powder in the high temperature period of fermentation, the temperature of fertilizer pile increased rapidly, but the temperature change was not obvious after adding monosodium glutamate residue.
Cow dung organic fertilizer fermentation equipment: to produce organic fertilizer with cow dung as raw material, fermentation must be carried out first. Cow dung itself has comprehensive nutrients. It is not only rich in essential nutrients such as organic matter, nitrogen, phosphorus, potassium and other trace elements, but also contains a variety of biological enzymes and microorganisms. However, they need to be absorbed by fermented cow dung, otherwise harmful substances will affect crops, not only can not provide nutrition, but also cause harm such as burning seedlings and pests.

Process flow of Organic fertilizer processing equipment

The equipment and process flow to be used in the early processing of organic fertilizer are as follows:
1. Trough conpost turning machine, or mobile compost windrow turner, the mobile compost windrow turner does not limit the site, while the trough compost machine needs to build a groove (the length and width of the groove are designed according to the actual size of the site), which is cleaner, hygienic and environmentally friendly. The materials are directly stacked in the fermentation tank, and a trough dumper can be used to dump and ferment multiple fermentation tanks through the transfer car.
2. Transfer the fermented organic fertilizer to the semi-finished product stacking area with loader feeding hopper, and the fermented organic fertilizer will be thrown by the compost windrow turner for for the next fertilizer production process every day.
3. Screening machine, screening the fermented organic fertilizer, and separating out the large blocks and sundries, so as to facilitate the next crushing and packaging.
4. Crusher, which will separate out the large debris and stones in the screened organic fertilizer and then crush them, so as to ensure the beauty and quality of the products.
5. The premixing machine can ensure the stability of the product quality by premixing the screened and crushed organic fertilizer, and at the same time, it can play a role in mixing the special fertilizer and various compound fertilizers when adding fertilizer and trace elements.

1. The impact of processed products on the price of organic fertilizer equipment
The finished products of organic fertilizer equipment mainly include powdered organic fertilizer, granular organic fertilizer, liquid organic fertilizer, mixed fertilizer, and other different finished products. There are significant price differences. As mentioned earlier, the production line processing capacity of powdered organic fertilizer with small production capacity requires less than 100000 yuan in equipment prices to achieve mass production and processing. Granular organic fertilizer is a super large capacity organic fertilizer equipment that was customized and assembled for foreign customers in 2017, with an equipment investment of over 2 million yuan.
2. Different prices of organic fertilizer equipment due to different process technologies
The difference in the price of organic fertilizer production lines also lies in the difference in process selection. There are options for using dedicated organic fertilizer granulators as the core process production line, disk granulators as the core process production line, and rotary drum granulators as the core process of the production line. Of course, currently, it is generally recognized that the process production line with superior performance should be based on the organic fertilizer combined granulator.

Product characteristics and scope of use of cage crusher

The cage crusher is a medium-sized horizontal cage shredder designed based on the principle of impact crushing. The inner and outer sets of cage bars rotate at high speed in opposite directions, and the materials are crushed through the impact of the cage bars from the inside out.

Problems in processing fertilizer in large-scale pig manure Organic fertilizer production line

For the production of organic fertilizer from pig manure, it is recommended to adopt aerobic fermentation treatment, which can be fermented with fermentation agent, so as to better the crops, and mix pig manure with straw, sawdust, mushroom residue, etc. in an appropriate proportion (80-90% of manure, 10-20% of others). 1 ton of material (about 2.5 tons of fresh material) is added with 1 kg of fertilizer fermenting agent, diluted with 1 kg of fertilizer fermenting agent and 5 kg of rice bran (or bran, corn flour and other substitutes), and then evenly distributed into the material pile. In the fermentation process, the compost windrow turner should be used to properly supply oxygen and turn over the pile, and the temperature should be controlled at 55-65 ℃. The water content of fermentation materials should be controlled at 60-65%.

The method of adjusting material water content: the water content of fermented pig manure and chicken manure should be controlled at 40-65%. Moisture judgment: hold a handful of pig manure tightly, see the watermark but do not drop water at the finger joint, and it is appropriate to disperse when landing. Water less fermentation slow, water more poor ventilation, therefore, we must grasp the water content. If the water content is too high, straw, sawdust, mushroom residue and dry soil powder can be added. Judge whether the moisture is suitable or not: hold a handful of materials tightly, see the watermark at the finger joint but do not drop water, and it will be scattered when landing. In general, the whole fermentation process can complete the complete deodorization, fermentation, decomposition, insecticidal sterilization and so on in 5-7 days.
Start up temperature of organic manure production line. The start-up temperature should be above 15 ℃ (it can be operated in four seasons, not affected by the season, and it is better to ferment indoors or in the greenhouse in winter), and the fermentation temperature should be controlled below 70-75 ℃.
Mix well and ventilate. The production of organic fertilizer by pig manure fermentation needs good (consumption) oxygen fermentation. Therefore, the oxygen supply measures should be increased in the fertilizer production process, and it is appropriate to mix well, turn frequently and ventilate. Otherwise, it will cause anaerobic fermentation and produce odor, which will affect the effect of fertilizer.
Fermentation complete. Generally, 48 hours after the pig manure is piled up, the temperature rises to 50-60 ℃, and the third day can reach above 65 ℃. Under this high temperature, the temperature can be turned over once. Generally, there will be two times of high temperature above 65 ℃ in the fermentation process. Turning over twice can not only complete the fermentation, but also complete the fermentation within a normal week. The material was dark brown, and the temperature began to drop to normal temperature, indicating that the fermentation was completed.

Process of powdered Organic fertilizer production line with chicken manure and straw as raw materials

The organic fertilizer production line is an equipment for mass production of bio organic fertilizers, which plays a very important role in the development of agriculture. The organic fertilizer equipment ferments crop waste and livestock waste, such as straw, corn cob, distiller’s grains, chicken manure, pig manure, and other manure containing organic substances, to produce organic fertilizer containing a large number of microbial strains. The microbial strains in the finished organic fertilizer can improve the soil structure, increase the content of organic matter in the soil, and use chemical fertilizers and compound fertilizers to greatly increase crop yield. After a certain process flow of fertilizer production line, high-quality organic fertilizer can be processed. Below is a complete set of production process flow of organic fertilizer production line:

1. First of all, mix chicken manure with a certain amount of straw powder, the amount of which depends on the water content of chicken manure. Generally, 45% of the water content is required for fermentation, that is, knead the chicken manure into a ball by hand, see the water through the fingers, but do not drip water, and release it to disperse.
2. Then add the mixture into the blender for mixing. The mixture must be even, transparent and free of lumps.
3. The raw materials are put into the fermentation trough to add the fermentation bacteria. The fermentation trough is built into a long strip of 2.5m wide and 0.8m-1m high, which is tossed once every 2 days by the compost windrow turner (the length, width and height of the fermentation trough can be determined according to the actual site). The main purpose of the fermentation is to quickly heat up, ferment, deodorize and kill harmful bacteria. Heaped for 2 days, odorless for 4 days, loose for 7 days, fragrant for 9 days and fat for 10 days. Specifically, on the second day of composting, the temperature can reach 60 ℃ – 80 ℃ (different temperature changes in different seasons), killing E.coli, insect eggs and other pests; on the fourth day, the odor of chicken manure is eliminated; on the seventh day, the compost becomes loose and dry, full of white hyphae; on the ninth day, a kind of distiller’s yeast fragrance is emitted; on the tenth day, the compost is fermented and matured.
4. The semi wet material crusher is used for crushing.
5. Then the impurities are screened out by the screening machine, and the powdered organic fertilizer is ready.
6. It can be stored by automatic packing scale.

Cost of building a production line with an annual output of 50000 tons of Manure

The configuration of the organic fertilizer production line is high or low. The configuration of the organic fertilizer production line with an annual output of 50000 tons is roughly as follows:
Step 1: organic fertilizer fermentation
The fermentation of organic fertilizer collects the excrement, mixes with hay and rotten silage to make compost and ferment it. In the process of fermentation, the compost windrow turner is used to fully ferment the feces and make aerobic composting. It is a method to make the organic fertilizer stable, harmless and then turn into high-quality fertilizer by using the compost windrow turner and fermentation bacteria under aerobic conditions
Step 2: crushing and mixing of ingredients
The composted materials, such as N, P, K and other inorganic fertilizers, and other additives are crushed, proportioned and mixed in a certain proportion through the material grinder and horizontal mixer by using the batching bin.
Step 3: Granulation
A new type of organic fertilizer granulator is used to granulate materials.
Step 4: screening and return system
There is a certain difference in the particle size of the particles output from the pelletizing and molding system, which requires screening and grading. The selected roller screen is used to screen the particles.

The investment price of organic fertilizer production equipment can be more or less. If we want to produce powdered organic fertilizer processing, we only need to invest in one fermentation equipment, crusher and screening machine. The investment is 60000 yuan. If we want to produce granular organic fertilizer, we need to add organic fertilizer granulator, dryer, annual output of 10000 tons of organic fertilizer generally do not need cooling machine. About 200000 yuan has been invested. The plant site can be large or small. Generally, the total site needs 3 to 5 mu of land.

The annual output of 2000-5000 tons of small-scale organic fertilizer machine production process needs about 100000 yuan, including organic fertilizer compost windrow turner, crusher, mixer, organic fertilizer granulator, screening machine, conveyor complete equipment. The traditional fertilizer granulation production process, such as disk granulation or drum granulation, requires a dryer, cooler and other complete equipment at a price ranging from 200000 to 300000. The pig manure organic fertilizer production process covers a small area, saves money, labor and has a good effect, which is the best choice for many initial small investment.

Production process of pig manure organic fertilizer:
The production of organic fertilizer by pig manure fermentation needs good (consumption) oxygen fermentation. Therefore, in the process of operation, oxygen supply measures should be increased to make sure that it is well mixed, turned over frequently and aerated. Otherwise, it will cause anaerobic fermentation and produce odor, which will affect the effect of fertilizer. Fermentation complete. Generally, 48 hours after the pig manure is piled up, the temperature rises to 50-60 ℃, and on the third day, it can reach above 65 ℃. In this high temperature, it can be turned over once by the fermentation compost windrow turner of Zhengzhou Huaqiang Heavy Industry generally, there will be two times of high temperature above 65 ℃ in the fermentation process. Turning over twice can complete the fermentation, which can be completed in a normal week or so. The material was dark brown, and the temperature began to drop to normal temperature, indicating that the fermentation was completed.
Industry development drives the improvement of economic level, which is the law of market development and an inevitable result. As an important pillar of the agricultural machinery industry, organic fertilizer equipment has always been ahead of the industry. In recent years, it has reached a higher technical level with the support of high-tech. In fact, through analysis, it can be found that the development of the agricultural industry is closely related to the organic fertilizer equipment industry. Through the promotion of organic fertilizers by the Ministry of Rural Agriculture, everyone has also understood that organic fertilizers are necessary for planting green organic food. Understanding this relationship, some friends have seen business opportunities and have invested in the organic fertilizer processing industry. However, when purchasing organic fertilizer equipment, they found that the prices of organic fertilizer equipment are diversified, ranging from within 100000 to millions of organic fertilizer production lines.
