fertilizer granulator Jul 28, 2023

The complete set of environmentally-friendly composite fertilizer equipment adopts a dry and normal temperature process for production, forming in one go with a production capacity of 1-2t/h. The composite fertilizer equipment has low investment, fast efficiency, good economic benefits, compact process layout, scientific and reasonable, advanced technology, energy conservation and consumption reduction, no three waste discharge, stable operation, reliable operation, convenient maintenance, wide adaptability of raw materials, and is suitable for composite fertilizers, pharmaceuticals, chemical feed, coal Granulation of various raw materials such as metallurgy, and production of compound fertilizers of various concentrations and types (including Manure, inorganic fertilizer, biological fertilizer, magnetized fertilizer, etc.).

Characteristics of environmentally-friendly composite fertilizer complete equipment

1. The compound fertilizer equipment is applicable to the direct granulation of fermented livestock manure, sugar factory filter sludge, urban sludge, paper making sludge, distiller’s grains, straw, peat and other coarse fiber organic wastes with moisture content of about 30%, and can produce spherical pure Manure, organic and inorganic fertilizer, and biological Manure.

2. The balling rate of compound fertilizer equipment and the survival rate of microbial bacteria are high. The new process can achieve a balling rate of over 90% -95%, and the low-temperature high air drying technology of the compound fertilizer production line can achieve a survival rate of over 90% for microbial bacteria.

3. The process flow of compound fertilizer equipment is short, and the operating cost is low. The organic raw materials used in this process do not require pre treatment such as drying and crushing. The process flow is short, and the operating cost is low (if traditional granulation processes such as disc or drum are used, the organic raw materials with a moisture content of about 30% after fermentation need to be dried to below 13%, crushed to over 80 mesh, and the amount of organic materials added cannot exceed 30%).

A set of Manure equipment is not what we imagine is a fixed equipment, but it needs to be determined according to the site and materials. For example, chicken manure has a lot of water. When fermenting, the water must be reduced, and corn cobs smashed with straw can be added. Otherwise, it cannot be granulated, while sheep manure is relatively dry. When fermenting, it can be granulated directly without straw, The equipment used varies depending on the process.

What should we pay attention to when lubricating the organic fertilizer machine?

With the best-selling of organic fertilizer, the use of organic fertilizer production line is also greatly increased. When we change the oil of organic fertilizer machine, we often have various problems. Today Zhengzhou Huaqiang Heavy Industry Machinery Co., Ltd. will analyze some precautions of changing the oil of organic fertilizer machine. When some users use fertilizer production process, in order to reduce the operating cost, they always use waste engine oil when exchanging engine oil, and then add half or 80% new engine oil for mixed use, which is often a small loss.
What should be paid attention to when lubricating organic fertilizer machine

Because the waste oil in the organic fertilizer production line is rich in many oxidizing substances, colloidal carbon particles and many iron scraps, it will greatly shorten the service life of the fresh oil and increase the speed of sports wear. If the oil level exceeds the marking line, it will not only increase the oil consumption, but also increase the carbon accumulation in the oil cylinder caused by the organic fertilizer granulator and the organic fertilizer grinder, which will accelerate the wear of the cylinder and other parts and shorten the service life.
Another situation is to save maintenance costs. The waste oil in the oil pan of the organic fertilizer production line will be poured into the gearbox, which will also be a small mistake. Because the transformed engine oil is rich in many mechanical impurities, participating in the gearbox will accelerate the wear rate of moving parts.
In addition, the waste engine oil will make the gear oil thin and the gear wear will be intensified. However, the replaced waste engine oil can be used in the air filter oil pan to save fresh engine oil.

The granulation process of drum granulator in compound fertilizer production line

fertilizer granulator Jul 28, 2023

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

fertilizer granulator Jul 28, 2023

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

fertilizer granulator Jul 24, 2023

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.

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

fertilizer granulator Jul 24, 2023

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

fertilizer granulator Jul 24, 2023

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.
