The roller shell is one of the key components in a pellet mill, used to process various types of biomass fuel granules, animal feed pellets, and other pellet products. It is made from wear-resistant alloy steel with carburization heat treatment, ensuring even hardness and a long service life. The roller shells come in different types such as tooth-through, tooth-no-through, and pass type. The inner eccentric shaft is precisely manufactured, allowing users to adjust the space between the roller and ring die according to their production needs. It is also easy to install and replace.

Key Features of FDSP Roller Shell
1. Made from high-quality wear-resistant alloy steel with advanced heat treatment processes.
2. High hardness, excellent wear resistance, and long service life. Available in different tooth depths and shapes.
3. Optimized tooth surface design enhances pelleting performance.
4. Common tooth forms include honeycomb, scallop, and scallop with edge banding.
5. Honeycomb and scallop types are mainly used in livestock and poultry feed production.
6. Honeycomb roller shells ensure even wear on the ring die but may have weaker coil performance.
7. Scallop-shaped roller shells offer better coil performance and are widely used in feed mills, though they may cause uneven wear on the ring die.
8. Scallop shape with edge banding is ideal for aqua feed, preventing material from slipping during extrusion.
We have a wide range of pellet mill parts available in stock.
Product Description
The roller shell, commonly known as the roller, is a critical working part of the pellet mill. It is used to process various types of biomass fuel granules, animal feed pellets, and other pellet products. Made from wear-resistant alloy steel with carburization heat treatment, it offers consistent hardness and an extended service life. It comes in different types, including tooth-through, tooth-no-through, and pass type. The inner eccentric shaft is manufactured with precision, enabling customers to adjust the gap between the roller and ring die based on their production requirements. Its design makes installation and replacement straightforward.
Important Notes
1. Choose the correct die hole compression ratio.
2. Adjust the clearance between the ring die and roller properly (between 0.1 to 0.3 mm). After turning on the new pellet mill, the roller should be in a pre-running state without rotating.
3. New ring dies should be used with new rollers. The roller connection should be loose at the front and tight at the back. If sharp corners appear on both sides of the roller, use a hand grinder to blunt the flange to ensure proper contact between the roller and die.
4. Before feeding raw materials into the pellet mill, perform cleaning and magnetic separation to reduce iron impurities entering the die holes. Regularly check the die holes for blockages and clean them as needed.
5. If plastic deformation occurs in the ring die's guiding cone hole, causing shrinkage, it must be repaired. During repair, ensure the lowest height of the ring die’s inner surface is 2mm higher than the bottom of the overtravel groove. Additionally, the eccentric shaft adjustment must allow for extra space; otherwise, the die should be scrapped.
