1. Working principle of organic fertilizer disc granulation production line:

Pre-added water into the ball disc type full disc balling method. The raw meal powder is evenly moistened by atomized water in the twin-shaft mixer to form a ball core with very uniform particle size, and then sent to the balling disc for balling. The moisture of the ball should be Control it at 12~14%. Most of the water should be added in the twin-shaft mixer, and only a small amount of supplementary water should be added to the ball forming plate. The amount of supplementary water should be controlled at about 0~3%.

For dry powder granulation, the raw material pellet core is directly added to the pelletizing disk and sprayed with an appropriate amount of water. After entering the pelletizing disk, the raw material pellet core is affected by centrifugal force, friction and gravity in the disk and moves along a parabola. Due to the bonding of the materials The properties and plasticity make the ball cores bond with each other and gradually grow up during the movement. When the parameters such as the inclination angle of the ball disk, the height of the disk edge, the rotation speed and the moisture content are constant, the balls of different particle sizes will press according to the different gravity due to the different gravity. Different breakaway angles roll downward away from the edge of the disc.

During the continuous rolling process of the material ball, the water in the ball is continuously squeezed out of the surface. Due to the adhesion of the material and the natural volatilization of the surface liquid film, the material ball has a certain strength, and then moves from the surface as the tilt plate rotates. The edges of the plate are discharged out of the plate.

2. Uses and characteristics of disc granulator:

The disc angle of the granulating disc of the disc granulator adopts an overall arc structure, and the granulation rate can reach more than 93%. The granulating disc is equipped with three discharge ports, which facilitates intermittent production operations, greatly reduces labor intensity and improves labor efficiency. , the reducer and motor are driven by flexible belts, which ensures smooth starting, slows down the impact force, and improves the service life of the equipment. The bottom of the granulating plate is reinforced with multiple radiated steel plates, which is strong and durable and not easy to deform. The thickened, weighted, and solid base design No anchor bolts are required for fixation, and the operation is smooth. The main gear of the granulator adopts high-frequency quenching, which doubles the service life. The granulator plate is lined with high-strength fiberglass, which is anti-corrosion and durable. This machine has the characteristics of uniform granulation and high granulation rate. , stable operation, sturdy and durable equipment, long service life and other characteristics, it is the ideal equipment chosen by the majority of users.
