The working principle and product characteristics of cow manure drum granulator

2024/03/06
 

The cow manure drum granulator is a molding machine that can manufacture materials into specific shapes. The main working method is wet granulation of pellets. By using a certain amount of water or steam, the basic fertilizer is fully chemically reacted in the cylinder after being humidified. Under certain liquid phase conditions, with the help of the rotational motion of the cylinder, the material particles are compressed and agglomerated into balls.

The working principle of the drum granulator is driven by the main electric motor to drive the belt and pulley, which are transmitted to the driving shaft through the reducer. The gear installed on the driving shaft is matched with the large gear ring fixed on the body and works in opposite directions. The material is added from the feeding end and passes through the inside of the cylinder. Through the special structure inside the cylinder, it is made into particles and finally flows out through the discharge port. Due to the continuous entry of materials and the continuous rotation of the granulator, large-scale production can be achieved.

The drum granulator is equipped with steam, gas ammonia, or the addition of phosphoric acid or nitrogen solution, phosphorus ammonia slurry, and heavy calcium slurry to complete the chemical reaction and heating process of compound fertilizer granulation inside the drum; Alternatively, a cold granulation process for adding a small amount of water to the compound fertilizer can be carried out. The materials that need to be granulated are moved through the cylinder, causing rolling and rotation when the cylinder is empty, and then agglomerated into balls at appropriate humidity and temperature to complete the granulation process.

Product features of cow manure drum granulator:

1. The ball forming rate reaches 70%, the ball forming strength is high, and there is a small amount of returned material with small particle size, which can be re granulated;

2. Heating with steam to increase the temperature of the material, reducing the moisture content of the material after balling, and improving the drying efficiency;

3. The cylinder body of the cow manure drum granulator adopts a special rubber plate lining or acid resistant stainless steel lining plate, which is corrosion-resistant and wear-resistant, and achieves automatic scar removal and tumor removal, eliminating the traditional scraper device.
