The production of high-efficiency organic fertilizers by organic fertilizer equipment production lines is also an environmental protection project supported by the state. In order to comply with the national policy, take the development of green circular agriculture as its own responsibility, and improve the economic benefits of customers, the invention of the organic fertilizer granulator machine is a better choice for organic fertilizer production equipment. secondary pollution.

Commonly used organic fertilizer granulator equipment are: disc granulator machine, drum granulator, wet granulator, drum extrusion granulator, flat die granulator, and tooth stirring granulator. The choice of granulator should be determined according to the local organic fertilizer sales market. If the shape requirements of the granules are different, the processing process of the organic fertilizer production line is also different, and the price of the organic fertilizer production line is also different. Choose the appropriate organic fertilizer granulator according to the specific process requirements. There are many types of granulators. The specific use is very different. Let’s learn about the drum granulator.

The organic fertilizer rotary drum granulator has no sticking phenomenon, which is conducive to the classification of dry and wet particles, and the relative granulation ratio is low, generally 40% -60%. Therefore, the reaction rate is high, but the requirements for the mixing and degree of material mixing in the mixing process are relatively low.

The new organic fertilizer granulator has a wide range of applications, especially for the granulation of light and fine powders. The finer the basic particles of the fine powder material, the higher the degree of sphericity of the particles, and the better the quality of the particles. In general, the particle size of the material before granulation must be less than 200 mesh. Typical application materials are chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc. Due to the particularity of raw materials such as livestock and poultry manure, organic fertilizer, degummed fertilizer, green manure, sea manure, cake fertilizer, peat, soil fertilizer, three wastes, microorganisms and other municipal solid waste granulation, the particles are irregular.

The working principle and function of organic fertilizer rotary drum drying equipment

fertilizer granulator Oct 31, 2023

Approximately 3.8 billion tons of livestock manure are produced annually in China, which has become the main source of environmental pollution. Proper utilization of feces can lead to better “waste utilization”, and livestock manure treatment equipment is a complete set of equipment for treating feces. Fecal treatment equipment can better dry feces, and can dry fresh feces with a high moisture content of 70-80% through high-temperature drying, disinfection, sterilization, decomposition and other processes to produce pure fecal organic fertilizer with a moisture content of less than 13%. The shape is a granular finished product and does not contain any chemical components, making it an ideal organic fertilizer for farmland.

The rotary drum drying equipment for manure production has made significant breakthroughs and innovations on the basis of the traditional single drum rotary dryer structure. From the perspective of drying mechanism, the exchange between materials and hot air flow is more comprehensive, scientific and reasonable, and all thermal indicators reach a high level. Suitable for drying various raw materials such as clay, gypsum, coal, slag, coal gangue, mixtures, dry mixed mortar, yellow sand, iron powder, etc. It is also suitable for drying raw materials in the production of phosphate and composite fertilizers, as well as various loose materials in industries such as metallurgy and chemical engineering.

The working principle of the rotary drum drying equipment for manure production organic fertilizer:

When the bottom temperature of the organic fertilizer rotary drying equipment in the production of bacterial residue reaches 400 ℃ -800 ℃, the material is fed into the feeding port by the elevator, and under the action of gravity, it is dispersed, crushed, and the dispersion device is uniformly distributed inside the dryer to flow (ensuring the heat exchange effect of the material inside the dryer). Hot gas is generated by the lower hot air furnace and moves from bottom to top, coming into contact with the material. Through various means such as heat conduction, convection, and radiation, heat is transferred to the material, causing the temperature of the material to continuously rise and the moisture to evaporate. Materials that meet the moisture requirements are discharged from the lower outlet, and gas with water vapor is extracted by the fan from the chimney.

How to distinguish between wet and dry organic fertilizer granulation equipment

fertilizer granulator Oct 26, 2023

There are many types of granulators for organic fertilizers, which are distinguished according to different raw materials, different output and different particle shapes. They are roughly divided into disc granulator machine, flat die granulators, tooth stirring granulators, and roller extrusion Granulator, round granulator. The fertilizer granulator machine price is also different, ranging from several thousand yuan to tens of thousands of yuan. Because the output is different, the size of the granulator required is different, there are very small granulators, and there are also large granulators.

Among them, organic fertilizer granulator machine is a large general term, which is mainly divided into two categories: wet method and dry method:

1. Wet granulator, which adds the main materials and auxiliary materials to be granulated into the mixer according to the appropriate ratio and formula, and the powder material and the binder are fully mixed at high speed by the bottom mixing paddle in the cylindrical container. After that, it is made into wet soft material, and then cut into uniform wet particles by the side high-speed pulverizing paddle, so as to achieve the purpose of granulation. It can also be equipped with vacuum drying and auxiliary system equipment to achieve one-step, and directly obtain finished products.

2. Dry granulator, its working principle is that after the material enters the horizontal feeder, driven by the rotating screw, the material is gradually degassed in the process of advancing, and the material with increased density is forced into the tablet press. . The tablet press rolls the high-density material conveyed by the horizontal feeder into a 2-4mm sheet through a pair of hydraulic cylinders (adjustable pressure) to push the pressure roller, and completes the degassing work again. The rolled sheet passes through the teeth of the shearing crusher, and is cut into pieces that are easy to granulate and then falls into the granulator. The fragments are forced out of the sieve plate under the extrusion of the sizing knife. After the extruded granules are screened, the products with the particle size required by customers can be obtained. So far, the whole process of granulation has been completed.

Operating instructions for the disc granulator of organic fertilizer equipment

fertilizer granulator Oct 26, 2023

Organic fertilizer granulation equipment: The granulation of mixed fertilizer is an important process in the granulation process. It is not only related to the internal and external quality of the product, but also related to the size of the output and the cost. In addition to the physical and chemical properties of the material itself, it is also closely related to the form and mechanical properties of the granulation equipment. The main types of npk fertilizer granulator are disc granulator, drum granulator, twin shaft granulator, extrusion granulator and spray granulation dryer, etc.

Precautions for operating the disc granulator:

1. Water content: the control of water content in the operation of the organic fertilizer equipment disc granulator. When the disc granulator is running, the inclined disc granulation process is adopted. The pelletizing process requires high moisture content, and poor moisture control can lead to a decrease in pelletizing speed.

2. Materials: Pay attention to the quality of various materials to ensure that sundries, large pieces and large particles are not mixed into the feed. In addition, they should pay attention to the temperature of the equipment feed, because if the temperature of the die is too high, the material can easily break and stick to the die after startup.

3. Disc inclination: Pay attention to the change of the inclination of the disc granulator during operation. The disc granulator machine has a certain inclination angle. If the inclination angle changes due to unexpected reasons, it will also affect the granulation rate of organic fertilizer granules and also affect the service life.

4. Body temperature: The operator should also pay attention to the temperature change of the body at any time. During the normal operation of the granulator, the operator should maintain a stable machine temperature and do not allow the temperature to rise and fall.

5. Speed: When using the disc granulator, in order to ensure that the produced particles are uniform, smooth and complete, attention should be paid to ensure that the feeding is uniform and sufficient, and the feeding speed and feeding speed of the equipment should be properly matched to avoid particle quality and Production fell.
