Pellet machine Spare Parts Roller Shell Pressure Rollers Customzied

The roller shell is one of the main working parts of pellet mill.The roller shell has  different types of structures such as tooth-shaped through-shaped, tooth-shaped blocked, and hole-shaped.

Our press roller shell is applicable for:
1.Biomass pellet machine: wood pellet mill, sawdust pellet mill, grass pellet mill, straw pellet mill, crop stalk pellet machine, alfalfa pellet mill etc.
2.Fertilizer pellet machine, all kinds of animal/poultry/livestock feed pellet machine.

Roller shell, commonly known as pressure roller, is one of the main work parts in pellet machine and is applied for processing various kinds of biomass fuel pellet, animal feed pellet and other pellets. It is made of wear resistant alloy steel with carburization heat treatment, featuring even hardness and long service life.

We can make all kinds of pellet mill roller shells according to customers' drawing.
1. Grade: First level
2. Size:1.0~20.0 mm
3. Certification: CE ISO SGS

Note :

1. Correctly select the appropriate die hole compression ratio;

2. Correctly adjust the working gap between the ring die and the pressure roller to be between 0.1 and 0.3mm (the pressure roller is driven by the ring die after the new granulator is turned on in a “like rotating but not rotating” state);

3. The new ring die should be used with a new pressure roller, and the pressure roller and the ring die must be loose before and then tightened. When sharp corners appear on both sides of the pressure roller, the flange of the pressure roller should be smoothed with a hand grinder in time to facilitate a good fit between the pressure roller and the ring die;

4. The raw material must undergo preliminary cleaning and magnetic separation before the pelletizer to reduce iron pressing into the die hole. And to check the die hole regularly to see if there is any blockage. Punch out or drill out the blocked mold hole in time;

Main technical paremeter of pressure roller shell :

• Size indication: outer diameter / inner diameter X width
• Surface processing type: through groove, closed groove, punching
