Fertilizer Machine Manufacturer Introduces How to Produce Compound Fertilizer Granules

The common granulation processes of compound fertilizer include tower granulation, rotary drum granulation (NPK fertilizer production line), spray granulation and so on. As fertilizer machine manufacturer, let’s introduce these production processes from the perspective of fertilizer production.

 

  1. High tower granulation process is mainly used for the production of high concentration nitro compound fertilizer. It can directly use concentrated ammonium nitrate solution, eliminating the links of spraying granulation, and granular compound fertilizer eliminates the process of crushing operation. At the same time, the compound fertilizer granules produced by the high tower granulation process are very uniform, the qualified rate is very high, the quality is good, easy to dissolve, and the caking phenomenon will not occur.

 

  1. Rotary drum granulator has little restriction on compound fertilizer formulation, high production yield, low investment and construction speed. It is favored by investors of small and medium-sized compound fertilizer plants and widely used in compound fertilizer production. The complete drum granulation process is a NPK compound fertilizer production line, which includes fertilizer granulator, automatic batching system, mixer, crusher, drum dryer, drum cooler, coating machine, packaging machine and other equipment.

  1. The spray granulation process adopts the slurry method. The slurry is sprayed into the equipment by heating and pumping, so that the moisture in the slurry is vaporized and separated, and the retained solid forms a granular compound fertilizer. This kind of process is widely used in large-scale compound fertilizer production. Its advantages are that it can be used to produce NPK compound fertilizer, and can also be used to produce ammonium phosphate compound fertilizer. At the same time, it has less energy consumption, large production scale and low production cost. The quality and strength of the products are very good.

Fermentation Mode of Chicken Manure Organic Fertilizer Manufacturing Process

Organic fertilizer, commonly known as farm manure, consists of various animal, plant residues or metabolites, such as human and animal manure, straw, animal residues, slaughterhouse waste, etc. Carbon-containing materials, mainly from plants and animals, are applied to the soil to provide plant nutrition as its main function. It not only provides comprehensive nutrition for crops, but also has long fertilizer efficiency. It can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity. It is the main nutrient in green food production.

The production of organic fertilizer must go through composting fermentation process. Composting is a process in which organic matter is continuously degraded and stabilized by microorganisms under certain conditions, and a product suitable for land use is produced.

Site selection

The site should be flat, near the water source and sunny from the leeward. It does not pollute the environment and is easy to provide water.

Common problems of NPK compound fertilizer production

NPK compound fertilizer is synthesized from chemical raw materials needed by various plants. NPK fertilizer has played a significant role in increasing production and income of agricultural production. So what are the common problems in the NPK fertilizer production process and what needs to be known about the equipment for the production of NPK fertilizer?

 

  1. Specialized NPK fertilizer production equipment is naturally used for fertilizer production, but due to the nature of compound fertilizer itself, fertilizer equipment is easy to be corroded, and some frequently used equipment has been seriously corroded in less than a year. Normal loss is inevitable, but necessary equipment maintenance can prolong the service life of fertilizer processing equipment.

 

  1. When crushing raw materials, we should try our best to ensure that there are no large hard blocks in the raw materials. In the compound fertilizer raw materials, if there are stones or even iron blocks, it will cause serious damage to the high-speed rotating mill rotor. Only by ensuring that the raw materials are clean and free of impurities can the equipment of fertilizer production process not be affected.

 

  1. Mechanical equipment relies on motor and reducer to obtain power source. Periodically adding lubricating oil to fertilizer granulator machinecan better ensure their operation. There are many types of lubricating oil, so we should choose suitable grease according to the principle of climate and mechanical transmission. For example, in cold areas and hot and humid environment, it is necessary to select the appropriate lubricant to ensure better operation of the equipment. In addition, when filling oil, control the amount of oil, so as not to affect the effect too little, or too much waste.

 

  1. Different equipments have different productivity. We should use the equipments reasonably according to their productivity. For example, in the compounding stage of fertilizer manufacturing process, forklift trucks should be allowed to drop materials slowly when feeding into silos, so as not to damage the equipment. When mixing, the raw materials should not be too full, and materials should be added after the start of the mixer, in order to avoid equipment damage due to excessive stirring resistance.

NPK fertilizer production process

In short, there are many details about the production of NPK fertilizer. Only by maintaining the fertilizer production equipment can they work better and bring us more benefits.

Bio-organic fertilizer production process and equipment

Bio-organic fertilizer refers to a kind of fertilizer that combines livestock manure as the main raw material, inoculates microbial complex microbial agents, completely kills the bacteria and eggs by fermentation, and turns macromolecules into small molecules. The biofertilizer project is to feed the fermented material into the organic fertilizer production line equipment and process it into commercial organic fertilizer.

biofertilizer project

Organic fertilizer production line and processing raw materials
Main ingredients: The raw materials for the production of bio-organic fertilizer are mainly agricultural waste such as livestock manure and crop straw.
Other ingredients: different sources of raw materials, fermentation methods, equipment, etc., the ingredients of organic fertilizer production are different. The specific formulation depends on the source of the organic material.

Fermentation and decomposing of bio-organic fertilizer process
The fermented materials can be stacked on the ground or fermented in the fermentation tank. Fermentation tanks are usually better in flattened or semi-closed fermentation chambers than on flat ground. The material needs to be turned over regularly by using a turning machine, and it is turned over every 3 days. After 25-30 days of fermentation, the temperature gradually decreases from 70-80 degrees Celsius to stable, and the ripening is completed.

Main equipment and process for biofertilizer project:
1. Crushing and stirring pretreatment
Crushing equipment: semi-wet material crusher
This machine is mainly used for the crushing of bio-fermented organic fertilizer materials with water content of 25%~50%. The pulverization particle size of the semi-wet material pulverizer meets the granulation requirements, and the machine can be adjusted within a certain range according to the needs of the user.

2. Mixing equipment: horizontal mixer
This machine is mainly used for batch mixing of raw materials, and the materials can be fully mixed. The horizontal mixer has high mixing strength and low residual amount, and is suitable for mixing feed, concentrated feed and premix additives.

3. Granulation equipment
The composted material is subjected to a granulation process so that it has a certain strength and shape to be applied as an organic fertilizer. Granulation is a key step in the production of bio-organic fertilizers. Bio-organic fertilizer has a variety of fertilizer granulator machine. According to the structure of the granulator, the pellet method can be divided into a disc granulator and a drum granulator. According to the position of the press rolls, the extrusion method can be divided into a roller press granulator, flat die granulator and ring die granulator.

The working principle of the disc granulator in the fertilizer production line

The disc granulator machine is mainly used in the NPK fertilizer production line and organic fertilizer production line to produce various granular products; it’s also used in pharmaceutical products, fertilizers, feeds, etc. Adopting the overall arc structure, the granulation rate can reach above 93%. The granulation tray has three discharge ports, which facilitates intermittent production operations, greatly reduces labor intensity and improves labor efficiency.

disc granulator machine

Disc fertilizer granulator machine working principle:
The raw meal powder is uniformly wetted by the atomized water in the mixer to form a spherical core having a uniform particle size, and then fed into a ball plate for ball formation. The moisture of the ball should be controlled at 12-14%. Most of the water should be added in the twin-shaft mixer. Only a small amount of supplementary water is added to the ball plate, and the amount of water added is controlled to be about 0 to 3%. The dry powder granulation is directly added to the ball-forming plate, and the proper amount of water is sprayed. The raw material nucleus enters the spherical disk and is subjected to centrifugal force, friction and gravity in the disk, and moves along the parabola. Due to the cohesiveness and plasticity of the material, the cores are bonded to each other and gradually grow up during the movement. When the inclination angle of the ball disc, the height of the disc edge, the rotation speed and the moisture are constant, the balls of different particle sizes roll downward from the edge of the disc at different disengagement angles due to different gravity. During the continuous rolling process, the ball continuously discharges the water in the ball out of the surface. Due to the cohesiveness of the material and the natural volatilization of the surface liquid film, the ball has certain strength, and then the disk is rotated with the tilting of the disk. The sides are discharged out of the pan.

Disc granulator performance advantages:
1. The raw materials are suitable for a wide range of applications. They can be used for granulation of various raw materials such as compound fertilizer, medicine, chemical feed, coal, metallurgy, etc., and can produce various concentrations and various types (including organic fertilizer, inorganic fertilizer, and magnetic fertilizer etc.) of compound fertilizer.
2. The disc granulator is light in weight, low in height, and flexible in process;
3. The machine has simple structure, convenient adjustment and superior performance.
4. The use of unique unpowered combination scraper integration reduces auxiliary power consumption.

5, high ball formation rate, large rounded particle strength, intuitive operation, easy maintenance and so on.

Fertilizer granulator machine is the core equipment for fertilizer manufacturing process. As one of leading fertilizer machine manufacturers in China, in addition to the disc granulator, we also produce other types of fertilizer granulator machines, and other equipment such as compost turning machines, mixer machine, crusher machine, etc.

Production Advantage of NPK Compound Fertilizer with Double Roller Granulator

NPK compound fertilizer production mainly deals with raw materials in the state of powder, bulk, solution and molten liquid to produce particles with certain shape and size. Fertilizer granulator machine is an important equipment for compound fertilizer processing. Generally speaking, many parameters of fertilizer granulator can be adjusted, so it can adapt to a large range of raw materials.

 

Although many conventional compound fertilizer equipments still use wet granulation process to produce spherical pellet fertilizer, extrusion granulation process has many advantages, among which the most important is: low energy consumption of roller granulator NPK fertilizer production process, no need for liquid binder in granulation, many kinds of raw materials can be used, and the composition of raw materials is flexible. The function of roller fertilizer granulator is applicable to a wide range of large or small devices. Therefore, extrusion granulation NPK fertilizer production process has attracted more and more interest. Many fertilizer factories are considering dry extrusion NPK fertilizer production granulation process in construction.

In dry roller granulator equipment, the powder is applied force and compacted between two pairs of rollers. As with powder material, the quality requirement of roller granulator is reasonable formula, all kinds of components are complete and mixed evenly.In addition, the quality of particles produced by the double roller fertilizer granulator has the following two indicators:

 

  1. Hardness

Generally speaking, manufacturers usually want the particles to be harder. But whether from the point of view of use effect or manufacturing cost, it can not be said that the harder the better. The particle hardness produced by the double roller fertilizer granulator can be measured by the particle hardness meter and expressed by the pressure. According to the variety of materials, it is generally 0.06-0-12 MPa.

 

  1. Powdered rate

The method of determining the pulverization rate is to put a certain number of finished granules in a special pulverization rate measuring instrument, and turn them over at a prescribed speed in a prescribed time, and then determine the proportion of the powder transformed from granules in all materials. Generally, the powdered rate should not exceed 10% and the quality product should not exceed 5%.
