(3) Crushing and granulation. It is to crush block materials into particles of appropriate size.

(4) Melt granulation. It is a method of granulation by cooling and hardening molten liquid.

(5) spray granulation. It is a method of directly granulating solid after concentration in liquid.

(6) Liquid phase crystallization granulation. It is a method that materials crystallize in liquid phase and agglomerate into spherical particles through liquid bridging agent and stirring.

This technology is widely used in pharmaceutical industry. Because the particle shape is spherical, it is also called spherical crystallization granulation method, which is abbreviated as spherulite granulation method.

Spherulite particles are pure material particles with good fluidity, filling and compression formability. In recent years, the technology has been successfully developed. That is, polymer copolymer precipitation is added in the spherulite crystallization process to prepare sustained-release, rapid release, enteric coated, gastric coated pellets, floating hollow pellets, biodegradable microcapsules, etc. Preparation of sustained release pellets.

After the fermented organic waste is screened by magnetic separation, the raw materials containing binder and other compatible components are measured according to the proportion requirements, and then lifted by bucket elevator to multi-dimensional high-efficiency mixer for rapid mixing.

The mixed material slides out of the mixing bin and is continuously and evenly sent to the extrusion granulator by the disc feeder to make cylindrical particles; The cylindrical particles are polished into spherical particles by the circular particle polishing and setting machine and formed by the belt.

The machine is sent to the drying, cooling and screening machine (three in one model). The particles are dried at low temperature and large air volume (≤ 65 ℃) in the front section of the drying cooling screening machine, and then enter the cooling section for air cooling. After sufficient cooling, the materials enter the screen installed at the end of the cylinder.

The screened finished product particles are transported to the finished product silo by the elevator and measured and packaged by the packaging system; The screened large particles are crushed and returned to the mixed granulation system; The screened small particles (basically without powder) can be made into small packages and sold directly.

The shell of granulator adopts thickened seamless steel pipe, which is firm and durable and not easy to deform. Coupled with the solid base design, it runs more smoothly.

Using the mechanical stirring force of high-speed rotation and the resulting aerodynamic force, the fine powder materials can be continuously mixed, granulated, spheroidized and densified in the machine to achieve the purpose of granulation. The particle shape is spherical, the sphericity is ≥ 0.7, the particle size is generally between 0.3-3mm, and the granulation rate is ≥ 90%. The particle size can be appropriately adjusted by the mixing amount of material moisture and spindle speed. Generally, the lower the mixing amount, the higher the speed, the smaller the particles, and vice versa.

Scope of application: This machine is especially suitable for granulation of light and fine powder materials. The finer the basic particle of fine powder material, the higher the sphericity of the particle, and the better the quality of the ball. Generally, the particle size of materials before granulation shall be less than 50 mesh. Typical application materials: chicken manure, pig manure, cow manure, carbon black, clay, kaolin, etc.

Wet organic fertilizer stirring granulator is suitable for organic wastes such as peat, sludge, chicken manure, livestock manure, lignite, sugar mill filter sludge, papermaking sludge, wine, straw, soybean residue, peat and so on. Direct granulation completely solves the key technical problems that cannot be solved by traditional granulation processes such as disk (drum) fermentation, and granulation with bio organic fertilizer as raw material.

How does organic fertilizer promote agricultural industry development?

With the continuous development of society and the continuous progress of science and technology, China’s economic level has been greatly improved, and the people’s living standard has also been greatly improved. Various factors have provided great convenience for the development of agriculture. However, in order to ensure the sustainable development of environment and the secondary service life of land, organic fertilizer machine came into being.

The organic fertilizer manufacturing process, such as the organic fertilizer produced by the organic fertilizer granulator, not only has a certain positive significance for environmental protection, but also reduces the irreversible pollution damage of many chemical fertilizers to the land and eliminates crops from the source.

The harm of residual chemicals to human body is more conducive to people’s health. In addition, organic fertilizer can increase the yield of crops and help to increase agricultural production.

According to the development of the market, organic fertilizer equipment must have a relatively broad development space. However, these are not worth showing off the capital of organic fertilizer equipment. In the long development process, only relying on a good living environment can not promote the maximum development of organic fertilizer equipment.

Therefore, the primary task of the current organic fertilizer equipment is to recognize its own shortcomings, seriously study the advanced organic fertilizer production technology, and reasonably integrate it into the actual research and development, so as to make the organic fertilizer equipment more in line with the market development after repeated improvement.

It can provide more comprehensive and satisfactory services for agricultural production. In the increasingly fierce market competition, the factor that can effectively support the rapid development of organic fertilizer equipment lies in the comprehensive strength of the equipment.

Quality organic fertilizer production from plant ash

Plant ash is the residue of firewood after combustion. It belongs to alkalinity. The main component is potassium carbonate (K2CO3) which can be used as fertilizer. Before the widespread use of chemical fertilizers, agricultural plant ash refers to the ash produced after burning and eating by mountain grass, straw and branches (excluding the ash produced by coal).

The production of plant ash fertilizer is usually stacked with a layer of plant ash and used after several months of maturity. In industry, plant ash is also used as the main raw material of biological fertilizer project to process biological organic fertilizer.

Plant ash shall not be mixed with other fertilizers during storage. Some farmers are used to putting ash in puddles and mixing it with organic fertilizer and straw, which is very wrong. Because the ash is alkaline, it will cause the volatilization of nitrogen in organic fertilizer and reduce fertilizer efficiency. Such treatment will not only waste fertilizer, but also pollute the environment.

Ashes must be applied separately. Plant ash cannot be mixed with organic farm manure and ammonium nitrogen fertilizer to avoid nitrogen volatilization loss, nor can it be mixed with phosphorus fertilizer to avoid phosphorus fixation and reduce the use efficiency of phosphorus fertilizer.

Therefore, when planning the fertilizer manufacturing process and using plant ash as organic raw material, the fertilizer plant should pay attention to the proportion of raw materials.

1. Soil application: since the ash is alkaline, cohesive soil, acidic or neutral soil should be used. Soil application can be used as base fertilizer, seed fertilizer and topdressing, as well as seedling raising and seedling covering (seed covering fertilizer).

When used as base fertilizer and seed fertilizer, the amount of fertilizer should not be too large, and should be isolated from seeds to prevent seed burning. Generally, 50-100kg per mu is appropriate.

It is suitable for centralized soil application, strip application or hole application, with a depth of 8-10cm, and covered with soil after construction. Mix the wet soil 2-3 times or spray a little water before application.

2. Topdressing outside the root: more than 90% of the potassium contained in plant ash is soluble in water, which is a quick acting potassium fertilizer. According to this characteristic, plant ash can be used as extraroot topdressing, that is, 1% concentration of plant ash extract can be used for foliar spraying.

3. Priority crops: plant ash is suitable for various crops, especially potassium free or potassium free and chlorine free crops, such as potato, sweet potato, tobacco, grape, sunflower, sugar beet, etc.

Plant ash can be used for potato, not only for soil application, but also for potato wounds. In this way, it can be used as seed fertilizer to prevent wound infection and decay.

How to dry wet compound fertilizer granules?

Particle drying is an essential step in the production line of nitrogen, phosphorus and potassium fertilizer. The state requires that the moisture content of compound fertilizer must be less than 30% to meet the national standard. Then in the process of compound fertilizer production, the water content of organic fertilizer after granulation reaches about 50%.

Sometimes even higher, the moisture content of dry particles has become an important link in fertilizer production.

In the drying process of fertilizer manufacturing process, it is very important to pay attention to the drying method. The fertilizer produced by the compound fertilizer equipment is full dry fertilizer. So how does compound fertilizer equipment produce dry fertilizer? What are the methods?

1. Mechanical dewatering method: mechanical dewatering method is to pressurize materials and then extrude some water. Common methods include pressing, sedimentation, filtration, centrifugation, etc. Mechanical dehydration is only used for the initial dehydration of raw materials. This method is not suitable for the production of particles.

Therefore, the moisture content of materials after mechanical dehydration is still high, generally 40-60%. However, mechanical dehydration is the most economical method, which is most suitable for the dehydration of poultry and animal feces.

2. Heating and drying method of compound fertilizer dryer: This is what we often call drum dryer drying method. It uses heat energy to enter the dryer barrel, and the temperature in the barrel reaches about 150 degrees. According to different materials, the temperature can be adjusted to evaporate the water in the materials.

A certain amount of heat energy is required to remove the water in the materials. This method usually uses air to dry the material. The air is preheated and sent to the dryer to transfer heat to the material, so that the water in the material evaporates to form water vapor, which is brought out of the dryer with the air.

The material can be heated and dried to remove the combined water in the material, so as to achieve the water content required by the product or raw material. This method can be applied to a variety of industries, and it is also one of the simplest methods to meet the requirements.

3. Chemical dehumidification method: this method uses hygroscopic agent to remove a small amount of moisture in gas, liquid and solid materials. Due to the limited dehumidification capacity of hygroscopic agent, it is now only used to remove trace moisture in materials. Therefore, this method is rarely used in production.

The extrusion granulation plant for producing multi-element potassium magnesium sulfate fertilizer has the advantages of small floor area, short process flow, convenient equipment operation, less construction investment and short construction period. Therefore, the compound fertilizer production line technology project is a short, flat and fast construction project, which has a certain popularization and application value in small compound fertilizer equipment production enterprises.

2. The traditional compound fertilizer production line adopts slurry method or humidified granulation method, which needs to introduce particles before granulation. In the process of fertilizer manufacturing, a large amount of energy is consumed in the drying of water, resulting in a large amount of waste gas and wastewater, Waste residue pollutes the environment.

Extrusion granulation of compound fertilizer production line is to extrude materials by external force. The granulation process does not need steam, which can save boiler construction investment and coal production cost. The compound fertilizer production line does not introduce water and has no drying process in the whole production process, which eliminates the large and expensive dryer in the traditional compound fertilizer production line equipment, and can be dried with fuel and drying equipment.

Therefore, the process of this compound fertilizer production line meets the needs of today’s energy-saving society.

3. In the traditional nitrogen, phosphorus and potassium fertilizer production line, hot blast stove and preheated air are used to dry the materials in the production process. Burning coal in hot blast stove will produce a certain amount of sulfur dioxide gas and pollute the atmosphere.

There is no need to burn fertilizer in the whole production process. Coal not only saves energy, but also does not produce sulfur dioxide gas. The traditional compound fertilizer production line will produce a large amount of dust and wastewater in the process of material crushing, mixing, drying, cooling and screening, which belongs to the process of cleaner production.

4. The fertilizer is less affected by the external environment (such as temperature and humidity) in the production process, with great operation flexibility and flexible process formula.

5. The compound fertilizer production line has high pelletizing rate, low moisture content, high particle strength, less system return and less caking in the production process, which has good economic benefits.
