**Features of FDSP Roller Shell**
1. Made from wear-resistant alloy material, processed through fine manufacturing and heat treatment.
2. Crafted from bearing steel, offering high hardness, excellent wear resistance, and a long service life. Available in different tooth depths and shapes.
3. The tooth surface design enhances pelleting performance.
4. Common tooth forms include honeycomb, scallop shape, and scallop with edge banding.
5. Honeycomb and scallop-shaped rollers are mainly used for livestock and poultry feed production.
6. Honeycomb-type roller shells ensure even wear on the ring die but have limited coil performance.
7. Scallop-shaped roller shells provide better coil performance and are widely used in feed mills, although they may cause uneven wear on the ring die.
8. Scallop shape with edge banding is ideal for aqua feed, preventing the feed from sliding during extrusion.

**Product Description**
The roller shell, also known as the roll, is one of the essential working components in a 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 uniform hardness and a long service life. It comes in three types: through-tooth, non-through-tooth, and pass type. The precision of rolling parts like the inner eccentric shaft allows for easy adjustment between the roller and ring die based on production needs. Additionally, it is designed for easy installation and replacement.

**Notes for Use**
1. Select the appropriate die hole compression ratio.
2. Adjust the clearance between the ring die and roller (ideal range: 0.1–0.3 mm). After starting a new pellet mill, the roller should be in a pre-run state without rotating.
3. New ring dies should be used with new rollers. The roller connection with the ring die 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 for better contact.
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 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 point of the ring die’s 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.
