Large drum granulator
Large-scale inorganic fertilizer drum granulator has the following advantages:
1. Large production capacity: The large-scale inorganic fertilizer drum granulator has a large structural size and can accommodate a large amount of materials for granulation. Its output per hour can reach several tons or even tens of tons, which can meet the needs of large-scale inorganic fertilizer production.
2. Good particle quality: During the drum granulation process, the material is rolled, collided and agglomerated, and the particles formed are relatively regular in shape, mostly spherical or approximately spherical. The particle size distribution of the particles is relatively concentrated, and it has high strength and stability, which is conducive to the storage, transportation and use of fertilizers.
3. Adapt to a variety of materials: The large-scale inorganic fertilizer drum granulator can adapt to a variety of inorganic fertilizer raw materials, such as urea, ammonium phosphate, potassium chloride, etc. By adjusting the formula and process parameters, it can produce inorganic fertilizer products with different nutrient contents and specifications to meet the diversified needs of the market.
4. High operational stability: The operation of the equipment is relatively stable, and the parameters such as the speed and inclination of the drum are easy to control and adjust, which can maintain a continuous and stable production state, reduce production interruptions caused by equipment failure or operation fluctuations, and improve production efficiency.
5. High degree of automation: Equipped with advanced automatic control systems, it can realize automatic control of key links such as feeding, adding water, adding steam, and speed adjustment, reduce manual intervention, reduce labor intensity, and improve the accuracy and consistency of the production process.
6. Energy saving and environmental protection: The use of efficient transmission devices and reasonable process design reduces energy consumption. Some rotary drum granulators are also equipped with exhaust gas treatment systems, which can effectively reduce the emission of dust and harmful gases and meet environmental protection requirements.
Structural composition of large-scale inorganic fertilizer drum granulator
It is mainly composed of a cylinder, a bracket, a transmission part, a large gear, a roller belt, etc. The cylinder is welded with high-quality medium-carbon steel plates, and usually has a special rubber plate lining or an acid-resistant stainless steel lining inside, which can realize automatic scar removal and tumor removal, and eliminate the traditional scraper device. The bracket part is welded with medium-carbon steel plates and channel steels, and the supporting wheel is made of high-quality anti-corrosion and wear-resistant materials. The transmission part includes the main motor, pulley, V-belt, reducer, etc. The motor drives the pulley, V-belt, and reducer to the main shaft to make the machine work.
Working principle of large-scale inorganic fertilizer drum granulator
The main motor drives the belt and pulley, which is transmitted to the driving shaft through the reducer. The split gears on the driving shaft mesh with the large gear ring fixed on the machine body to rotate the drum. The material is added from the feed end. In the drum, a certain amount of water or steam is passed through the drum to make the basic fertilizer fully react chemically after being humidified in the drum. Under certain liquid phase conditions, with the help of the rotating motion of the drum, the material particles are squeezed and agglomerated into balls, and finally flow out through the discharge port.
Performance characteristics of large-scale inorganic fertilizer drum granulator
- Strong production capacity: The output of large-scale drum granulator can reach several tons or even tens of tons per hour, which can meet the needs of large-scale inorganic fertilizer production.
- Excellent particle quality: The particles formed are regular in shape, mostly spherical or nearly spherical, with concentrated particle size distribution, high strength and stability.
- Wide material adaptability: It can adapt to a variety of inorganic fertilizer raw materials such as urea, ammonium phosphate, potassium chloride, etc., and can produce products with different nutrient contents and specifications.

- High degree of automation: Equipped with advanced automatic control system, it can automatically control key links such as feeding, adding water, adding steam, and speed adjustment.
Operation process of large-scale inorganic fertilizer rotary drum granulator
Before starting the machine, check whether all parts of the equipment are normal, including whether the bolts are loose, whether the lining is intact, whether the transmission device is lubricated, etc. Start the machine without load first, and then feed after confirming that there is no abnormality. During the production process, it is necessary to reasonably control the parameters such as feed amount, moisture, steam amount, and drum speed according to the material characteristics and product requirements. Before stopping the machine, stop feeding, wait until the material in the drum is basically discharged, then turn off the power, and then clean and maintain the equipment.
Maintenance
Regularly check the wear of the drum, especially the lining part, and replace it in time if it is damaged. Check and lubricate the transmission parts such as reducers, gears, belts, etc. to ensure their normal operation. Clean the dust and debris on the surface of the equipment to keep the equipment clean. At the same time, check the electrical system regularly to prevent electrical failures.
