**Features of FDSP Roller Shell**
1. Made from wear-resistant alloy material, processed through fine machining and heat treatment.
2. Constructed from bearing steel, offering high hardness, excellent wear resistance, and long service life. Tooth depth and shape can be customized.
3. The tooth surface design enhances the pelleting performance.
4. Common tooth forms include honeycomb, scallop, and scallop with edge banding.
5. Honeycomb and scallop types are primarily used in livestock and poultry feed pelleting.
6. The honeycomb roller shell ensures even wear on the ring die but has poor coil performance.
7. Scallop-shaped roller shells provide good 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 feed from sliding during extrusion.
We have a large stock of pellet mill parts available for immediate delivery.
**Product Description:**
Roller shell, commonly referred to as the roller, is one of the essential components in a pellet mill. It is used to process various types of biomass fuel granules, animal feed pellets, and other types of pellets. Made from wear-resistant alloy steel with carburization heat treatment, it offers uniform hardness and an extended service life. The roller shell comes in different types, including through-tooth, non-through-tooth, and pass type. Precision in the size of rolling parts like the inner eccentric shaft allows customers to adjust the space between the roller and ring die according to their production needs. It is also easy to install and replace.

**Notes for Use:**
1. Choose the appropriate die hole compression ratio.
2. Adjust the working clearance between the ring die and roller, ideally 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 paired with new rollers. The roller connection must 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 part for better connection.
4. Before feeding raw materials into the pellet mill, perform preliminary cleaning and magnetic separation to reduce iron impurities entering the die holes. Regularly check the die holes for blockages and clean them if necessary.
5. If plastic deformation occurs in the ring die’s guiding cone hole, causing shrinkage, repair is required. During repairs, ensure that the lowest height of the ring die inner surface is 2mm higher than the bottom of the overtravel groove. Also, the eccentric shaft adjustment must allow extra space; otherwise, the ring die should be scraped.
