READ MOREOur disc pelletizers feature disc diameters ranging from 1m to 7.5m, disc inclinations of 35-55°, rotation speeds of 1-25 r/min, and motor power ranging from 3kW to 160kW. Available in two series, with and without powered scrapers, they can meet a variety of pelletizing needs.
Applications
Lump and powdered materials
Product Introduction
Our Pan pelletizers are available in two types: the non-powered scraper Pan pelletizer (PQW) and the powered scraper disc pelletizer (PQ). Both types feature simple structure, easy operation, easily controlled moisture content, and high pellet strength. The Pan features a monolithic structure with a base reinforced with multiple radial steel plates for durability. The reducer and motor utilize a flexible belt drive, ensuring smooth startup, reducing impact force, and extending equipment life.
Key Advantages
● Convenient ball Pan tilt adjustment, novel structure, light weight, low height, and flexible process layout.
● Simple structure, easy operation, easy control of ball moisture, and high strength.
● A unique combined scraper mechanism (bottom scraper and vertical scraper) reduces auxiliary power consumption.
● Particle size and output can be controlled by adjusting the ball Pan tilt, motor speed, and water spray volume.
Operating Principle
Raw material powder is formed into uniformly sized ball cores and then fed into the ball Pan. Once inside, the ball cores are subjected to centrifugal force, friction, and gravity, causing them to move along a parabolic trajectory. The continuous rolling process pushes moisture out of the ball surface. Due to the cohesiveness and plasticity of the material, the ball cores bond with the raw material powder during this movement, gradually growing in size. The cohesiveness of the material and the natural evaporation of the surface liquid film give the ball a certain strength. When the parameters of the ball forming disk, such as the inclination angle, disk edge height, rotation speed and moisture content, are constant, balls of different particle sizes will leave the disk edge at different separation angles and roll downwards due to different gravity, and then be discharged from the disk edge as the inclined disk rotates.
