Working Principle of Rotary Drum Granulator

The working principle of rotary drum granulator is that the belt and pulley are driven by electric power, the drive shaft is driven by a reducer, and the split gear installed on the drive shaft cooperates with the large gear ring fixed on the body to achieve the opposite work. The material enters the cylinder from the inlet end. Under the special arrangement inside the cylinder, it is made into granules and then flows out through the discharge port. Continuous feeding and continuous twisting granulator can realize mass production. A variety of compound fertilizers can be configured.

The machine is fed with steam, gas ammonia or added with phosphoric acid or nitrogen solution, phosphorus ammonia slurry, heavy calcium slurry to complete the chemical reaction and heating of the compound fertilizer pelletizing process in the cylinder; or the cold pelletizing process of compound fertilizer with a small amount of moisture. The material to be pelletized is rotated through the cylinder, and the material is not rolled and rotated in the cylinder, and then adhered to the ball at a certain humidity and temperature to complete the ball making process.

Bearings bear the entire load of the machine, so good lubrication has a great bearing life, it directly affects the service life of the machine and the operating rate, thus requiring the injection of lubricant must be clean, the seal must be good, the main oiling place of this machine (1) rotating bearings (2) roll bearings (roll bearings) (3) all gears (4) active bearings, sliding plane.
