The drum granulator is a commonly used fertilizer production machine. In the steam granulation process, the pellets are mainly clad, so the material circulation volume should be larger, so this can provide a larger coating process Nuclear, and the water injection volume should be smaller, so that the water absorption of the core can be reduced. When pelletizing by bonding or "gathering", the moisture content of the material is smaller, because at this time, the material in the rotary drum is mainly composed of fresh materials with small particle size and mutual bonding. The liquid ratio required for bonding should be large, because the space between the fine powder particles to be bonded with each other should be filled with water. The main structure of the rotary drum granulator is an inclined rotary cylinder, the drive can be constant speed or variable speed. When the liquid content of the feed powder is appropriate, agglomeration occurs and rolls in the drum. The drum has a certain slope, and the included angle between its axis and the horizontal is below 10 °, which can help the material roll along the long direction of the drum. The feed end is often equipped with a retaining ring to prevent the material from flowing back. A retaining ring can also be installed at the discharge end of the drum granula​tion production process to increase the thickness of the material layer and extend the residence time in the main drum. In other occasions, a spiral discharge ring is often used to convey boredom to the drum. At the end of the screen. Sometimes the cylindrical screen is integrated with the drum to form a product discharge port.

Operation precautions of NPK fertilizer granulation coating

In the NPK fertilizer manufac​turing process, a coating process is added to make a slow-release fertilizer. Slow-release fertilizer is also called controlled-release fertilizer. The release rate of nutrients in fertilizers can be controlled to a certain extent for continuous absorption and utilization by crops. After the fertilizer is coated, it can reduce the loss of fertilizer nutrients, especially nitrogen, in the soil. Can reduce the frequency of fertilization, save labor and cost. To increase crop yield and income, the application of slow-release fertilizer can improve crop resistance to disease and lodging.

The amount of coating agent is controlled according to the length of particle preservation in NPK fertilizer manufacturing process. So what are the precautions about the coating of NPK fertilizer granulation?Fertilizer granule coating machine is composed of screw conveyor, mixing tank, oil pump, main machine, etc. It can effectively prevent the caking of organic fertilizer and compound fertilizer, and is an effective coating fertilizer manufacturing equipment.

Fertilizer equipment plays an important role in the production of organic fertilizer. The daily maintenance of fertilizer manufacturing equipment is also very important. Otherwise, it will be damaged suddenly and delay the work. At the same time, it is not conducive to the maintenance and maintenance of the machine itself and reduce the service life. Therefore, we should pay special attention to the use of organic fertilizer equipment to ensure the smooth operation of fertilizer manufacturing equipment. The following describes the equipments required for biofertilizer production, as well as safe operation precautions. 1. It is easy for the newly installed organic fertilizer equipment to loosen the tyre, which must be checked frequently to see whether the machine works normally. 2. Pay attention to check the wear degree of the easily worn parts, replace the worn parts at any time, and place the underframe plane of the moving device. Dust and other things should be removed first to prevent the moving bearing from moving on the underframe when the machine encounters materials that can not be removed, thus causing major liability accidents; 3. If the temperature of bearing oil rises during the whole process of drum granulation, stop working immediately and start to check the cause of the accident and eliminate it. If there is impact sound when rotating the gear, the work shall be stopped immediately to find out the cause of the accident and eliminate it.

How is the bio-organic fertilizer equipment granulated and processed

In the process of organic fertilizer processing, organic fertilizer equipment is completed through a certain process, from the production to the finished product only a few kinds of equipment can achieve the goal. The equipments required for biof​ertilizer production https://www.zztchi.com/industry-info/how-choose-purchase-biofertilizer-production-equipment.html , mainly include fermentation compost turner, crusher, screening machine, packaging machine, etc. The following is about how the organic fertilizer equipment is granulated and processed.

Organic fertilizer production and granulation equipment

We often use bio organic fertilizer in agricultural planting, and organic waste is its processing raw material. Chicken manure and crop straw as the main raw materials, after fermentation, they are further made into high-quality organic fertilizer products by drum granulation. The fermentation process can decompose chemical pesticide and chemical fertilizer residues, improve fertilizer quality and increase fertilizer disease resistance.

Bio organic fertilizer is rich in nutrients, which can improve the soil and improve the soil consolidation caused by the application of chemical fertilizer. Improve the physical and chemical properties of soil, enhance the ability of soil water conservation and fertilization. According to the equipments required for biofertilizer production, the production process can be divided into flat composting and tank fermentation.

The factors affecting the safety of bio organic fertilizer are as follows

1、 Organic pollutants: these pollutants come from sludge, crop straw, etc.

2、 Antibiotics, organic arsenic: This is extracted from a variety of antibiotics widely used in animal husbandry, most of which are excreted with feces and urine in the original form of drugs. Pig manure, chicken manure and other livestock wastes are widely used in agricultural production as raw materials of bio organic fertilizer. The amount of antibiotics entering the soil every year is no less than that of pesticides, and enters the food chain through soil fertilizer. Some veterinary drugs are more toxic to the metabolites excreted in feces.

3、 Heavy metal pollution: the main pollution sources are mineral raw materials for production, smelting waste acid, heavy metal contaminated sludge, etc. Heavy metal pollution is common in phosphate fertilizer products and compound fertilizer products. In addition, the content of inorganic impurities such as salt in some chemical fertilizers is too high, which will not only cause soil salinization, but also cause seedling burning or yield reduction.

4、 Another type is pathogens and eggs, which are derived from untested microbial strains and can cause infection in humans or animals. Unsafe factors in the use of strains are also gradually expanding, and strains harmful to humans, animals and plants may flow into production. Some conditional strains may flow into the production chain, resulting in safety problems.

Features of double roller granulator

​Fertilizer manufacturing equipment processes organic wastes from agricultural production into organic fertilizers, and re-invests them in agriculture to realize the recycling of agricultural system. Organic agriculture is the combination of cultivation and aquaculture, as far as possible in agricultural production using waste processed into organic fertilizer, reduce production costs. Organic fertilizer manufacturing equipment is the key to organic agriculture. Organic agriculture regards the whole farm as an organism and realizes the nutrient cycle within the farm as closed as possible. If a farm has aquaculture and processing industries corresponding to land production, the nutrient cycle of plants will be maximized within the farm, and the nutrient transfer between farms will be minimal. Organic fertilizer production line is the bridge to realize the conversion of crop straw, residue and other wastes.

Processing of organic fertilizer production line

Wastes from agricultural production and livestock farming were collected and composted for high temperature fermentation. The pre-treatment of organic fertilizer production line mainly utilizes the function of various microorganisms to mineralize, humify and innocuously plant organic residues, so as to transform various complex organic nutrients into soluble nutrients and humus. At the same time, the high temperature produced during accumulation is used to kill the germs, eggs and weed seeds in raw materials, so as to achieve the goal of harmlessness.The decomposed materials are sent to the organic fertilizer production line equipment for further processing of organic fertilizer. The equipments required for biofertilizer production mainly includes compost crushing, ingredients of different raw materials, mixing, granulator machine to granulate organic fertilizer, drying and cooling, screening of finished products, and quantitative packaging.

High economic value of organic fertilizer production line

What are the benefits of sheep manure processed by organic fertilizer production line

After three or four days of fermentation, you will find that there is basically no odor in the feces. After the fermentation of sheep manure, the color of the fermentation pile will be darker, and the color of the pile will be brown after the fermentation. When the fermentation of sheep manure organic fertilizer is completed, the compost can be crushed and packaged, or it can be made into granules by disc granulator machine for further processing.

The key to fermented organic manure

1. Moisture adjustment. If the moisture is high, add some dry sheep dung or rice waste, straw, wheat straw, mushroom residue, residue and other agricultural waste. Usually the water of sheep manure is relatively small, and it needs to be adjusted by spraying water or adding fresh cow manure, chicken manure and pig manure.2. Use a compost turning machine. If you want to decompose and rot sheep manure quickly, you must turn the materials regularly to make the bacteria and enzymes decompose and rot sheep dung protein quickly.3. Pay attention to the specifications of the fermentation reactor. It is also important to note here that the pile should not be too small or too high, and it is not conducive to fermentation. Can choose to pile up in piles for aerobic fermentation of compost. It is also possible to build fermentation tanks to pile up materials.

Only by strictly restricting the amount of fertilizers and pesticides, improving the soil, and reducing the amount of drug residues in the soil can the farmer produce high-quality, safe and green products that are popular at home and abroad. The green active natural organic fertilizer is a new type of biologically active fertilizer, which has the characteristics of no pollution. It uses organic fertilizer as a substrate and carrier, and the sheep dung after fermentation can be used as organic matter. Add appropriate amount of inorganic elements to the organic fertilizer, and then add beneficial microorganisms that are beneficial to soil structure, crop absorption, element release, etc., and bioactive fertilizers can be obtained by processing on the organic fer​tilizer production line.

Working principle and application of particle fertilizer screening machine

Particle screening machine is a screening equipment for classifying the size of materials, which is widely used in the fine and coarse screening operations of powder or particle materials such as fertilizer plants, granaries, coal yards, stone factories, wood processing plants, etc. Our screening machine adopts special screen, which has high screening efficiency and long service life; it has small installation inclination angle, and the screen hole is not easy to block; it has simple structure and convenient maintenance; it operates stably with low noise; it occupies small space and is convenient for process layout. The granules made by the disc granulator machine can be directly sieved to obtain fertilizer products of qualified size.

Working principle of particle fertilizer screening machine:

The particle screen is installed on the frame in an inclined way. The motor is connected with the roller device through the reducer through the coupling, and the roller device is driven to rotate around its axis. The screen machine can be used to screen powder and particles, and has a wide range of applications. It can be used for the screening of organic fertilizer powder and the processing screening of compound fertilizer rotary drum granulator. When the material enters the drum device, due to the inclination and rotation of the drum device, the material on the screen surface will turn over and roll, so that the qualified material will be discharged through the discharge port at the bottom of the rear end of the drum, and the unqualified material (the product on the screen) will be discharged through the discharge port at the tail of the drum. Due to the overturning and rolling of the material in the drum, the material stuck in the screen hole can be ejected to prevent the screen hole from blocking.

Why to buy modern organic fertilizer processing machine

The traditional artificial composting is not suitable for the development of modern agriculture. The simple composting method has a long time to treat livestock manure, a low content of organic fertilizer nutrients and a slow release. After years of development, modern organic fertilizer production machine has become the development trend of organic fertilizer production in the future.

The modern organic fertilizer processing equipment has the following advantages in large-scale treatment of livestock and poultry manure:1. The organic treatment time was shortened from 30-90 days to about 15 days.2. It can deal with a large number of livestock manure every year, and realize the continuous production of organic fertilizer.3. The scale of organic fertilizer production line can be designed according to the output of livestock and poultry manure, with large processing capacity.4. The whole process of livestock manure treatment is controllable, and the processing process does not pollute the environment.5. The treated organic fertilizer has high nutrient content and is convenient for transportation and use.

In the production and processing of organic fertilizer, most of the organic fertilizer products are just simple fermentation, such products can only reach the harmless standard. The fermentation process of high-quality organic compost still needs aging and standing. This is because in the early heating and high temperature stage of composting, plant pathogenic bacteria, insect eggs, weed seeds and other harmful microorganisms will be killed, but the main role of microorganisms in this process is metabolism, reproduction, and only a small amount of metabolites. These metabolites are unstable and not easily absorbed by plants.In the later stage, microorganisms can only produce humus of organic matter, in which a large number of metabolites are produced, which are beneficial to plant growth and absorption. This process takes longer. Composting process can achieve three goals: first, harmless, second, humus, third, a large number of microbial metabolites, such as antibiotics, proteins, etc.

How to solve the problem that the powder of roller granulator is not granulated?

Raw material applicability and wide range of roller granulator

The roller granulator is not only suitable for the direct granulation of livestock manure, sugar factory filter mud, municipal sludge, straw, peat and other coarse fiber organic wastes with water content of about 30%, but also suitable for the extrusion granulation of compound fertilizers such as ammonium chloride and ammonium bicarbonate. The pelletizer can extrude elliptical granular compound fertilizer and feed.

High pelletizing rate of roller granulator and beautiful finished products

The fertilizer production process of roller press granulator makes the pelletizing rate reach over 95%, the extruded particles are round and standard, and the strength is high. The use of rotary drum granulatorrequires drying, cooling and other processes, while the double roller pelletizer has a short fertilizer production process and low operating cost, which is particularly suitable for dry granulation. The crushing and separating part of extrusion granulation particle: the material flows into the crushing chamber at the lower side after being extruded, and the ball and the returned material are separated and re granulated through the rotation of the biaxial hammer, so that the raw material for granulation can be fully utilized.

What to do if the powder is not granulated?

In the organic fertilizer production line, the material is required to have a certain viscosity. Some raw materials are loose after fermentation, and it is not easy to granulate. Therefore, some moisture or binder must be added to increase the viscosity of the material. Moreover, some fertilizer production lines are produced by a non-drying normal temperature process, and the double roller extrusion granulator are suitable for granulation of materials with relatively low water content. If the moisture content of the material is too high, some dry materials can be added in an appropriate amount to neutralize the moisture content. If the water content is too low, the appropriate amount of water can be added to make the material easy to granulate.

Recovery method of cassava residue-fermentation to produce organic fertilizer

Cassava residue is the by-product of cassava starch extraction or alcohol processing, mainly including crude fiber, crude ash and moisture. Indonesia, Cambodia, Thailand and other Southeast Asian countries produce a large number of cassava slag powder and cassava slag particles. As cassava residue is non-toxic, it is often used as a cheap source of coarse feed by the farms. Cassava residue can also be used as organic fertilizer after fermentation. A large number of cassava dregs can be recycled and reused by the fertilizer production machine.

There are many disadvantages in traditional cassava residue fermentation

Bio-fertilizer is a kind of product that leads to the specific fertilizer effect of crops caused by the life activities of microorganisms, and it is a kind of finished fertilizer in the organic fertilizer production line. It has a huge effect on crop growth and soil nutrition. Here we introduce the application of microbial bacterial fertilizer in the organic fertilizer production line.

Design of roller granulator for ammonium sulfate

Coated controlled release fertilizer

The traditional chemical fertilizer, such as N or a certain proportion of N, P, K compound fertilizer, is coated with a special biological or chemical water soluble polymer film. Based on the characteristics of film thickness, particle radius, diffusion coefficient, nutrient composition and dissolution, the release rate and amount of fertilizer nutrient are controlled according to the time of growing nutrient demand of crops, so that the release rate of fertilizer nutrient can fully match the needs of crops.

What are the advantages of coated controlled release fertilizer?

1. Reduce human management cost

After the fertilizer is made into particles by the rotary drum granulator, the coating process is carried out. The coated fertilizer greatly reduces the times of artificial labor fertilization, reduces the amount of fertilizer used, and reduces the loss of fertilizer, thus saving time, labor and money.

2. Increase of economic benefits

The coated controlled-release fertilizer can improve the fertilizer utilization rate, which is the key to save agricultural cost and increase product benefit. Before the fertilizer is coated, it should be pelletized by disc granulator machine. Therefore, the effect of granular fertilizer is long-term and stable. The energy of fertilizer can continuously supply the demand of nutrients for the whole growth period of crops. The benefit of coated controlled-release fertilizer is 1-2 times that of conventional fertilizer, which can improve the output and quality of agricultural products and increase the added value of fertilizer to crops.

3. Safe and harmless
