**Features of FDSP Roller Shell**
1. Made from wear-resistant alloy raw material, processed with fine and heat treatment.
2. Constructed 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 shape with edge banding.
5. Honeycomb and scallop-shaped roller shells are mainly used in livestock and poultry feed pelleting.
6. Honeycomb roller shells provide even wear on the ring die, though their coil performance is not as good.
7. Scallop-shaped roller shells offer 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 feed from sliding during extrusion.
We have a large stock of pellet mill parts available for immediate delivery.
**Product Description**
Roller shell, commonly known as a roller, is one of the main working components in a pellet mill. It is used to process various types of biomass fuel granules, animal feed pellets, and other similar materials. The roller shell is made from wear-resistant alloy steel with carburization heat treatment, ensuring uniform hardness and a long service life. It comes in different types, including through-tooth, non-through-tooth, and pass types. Precision manufacturing ensures ease of adjustment between the roller and ring die based on production needs. Additionally, it is easy to install and replace, making it a reliable choice for pellet mill operations.

**Notes for Use**
1. Choose the appropriate die hole compression ratio.
2. Adjust the working clearance between the ring die and roller (0.1–0.3 mm is recommended). After starting a 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 must be loose at the front and tight at the back. If the roller edges become sharp, use a hand grinder to blunt the flange part to ensure proper contact with the ring 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 cone hole of the ring die guiding material, causing the hole to shrink, repair it immediately. During repairs, ensure the inner surface of the ring die is at least 2mm higher than the bottom of the overtravel groove. Also, make sure the eccentric shaft has enough space; otherwise, the ring die may need to be scraped.
