Brief introduction of pellet machine flat die

The shape of pellet machine flat die is discoid and many holes spread on it. The cylinder shape of final pellets are formed through these holes. The diameter of holes is from 2mm to 10mm, they are manufactured according to your specific raw material to make sure best yield of your pellets.

Rollers of pellet mill

  • Model: 150, 200, 230, 260, 300 type
  • Power: 10-41 HP
  • Capacity: 40-800 KG/H

Brief introduction of pellet mill rollers

Usually, pellet mill rollers are covered with steel shells, they have high stiffness and rough surface, so which can ensure the strength of the extrusion. In the process of pellets production, the friction between the rollers and the die is frequent, so they are easy to wear. Big diameter rollers have more higher output capacity, the made pellets have more higher molding rate, more higher hardness and more homogeneous size.

Working Principle of pellet mill rollers

Pellet mills have D-type and R-type, the differences are the rollers. Rollers are important parts of pellet mills, which also have D type and R type. D type is rotating die type, which means the roller is fixed and the flat die is rotating with the main shaft. On the contrary, R type is rotating roller type, it means the roller is rotating with the main shaft and the flat die is fixed. When the pellet mill works, the raw materials are pressed by the roller and flat die, then become the shape of strips and emerge on the other side of the die, the blade cut them into the same length finally.

How to maintain flat dies and rollers?

Before working, you should check the die and roller of pellet machine for ensuring that no foreign body on the surface and no wear. After a period of time, the flat die of pellet machine should be turned to the other side, especially a thin die. When the both sides of die are not good to use or the made pellets are not hard, you need to change a new die. Generally, you can replace the press mill rolls together when replacing the new die.
