**Features of FDSP Roller Shell**
1. Made from wear-resistant alloy material, processed with fine machining and heat treatment.
2. Constructed from bearing steel, offering high hardness, excellent wear resistance, and a long service life. Available in various tooth depths and shapes to meet different needs.
3. The tooth surface design enhances pelleting performance.
4. Commonly used tooth forms include honeycomb, scallop shape, and scallop with edge banding.
5. Honeycomb and scallop-shaped roller shells are primarily 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 provide 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 the feed from sliding during extrusion.
We have a large stock of pellet mill parts available for immediate delivery.
**Product Description**
The roller shell, also known as the roller, is one of the key components in a pellet mill. It is used for processing 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 an extended service life. The roller shell comes in different types, including through-tooth, non-through-tooth, and pass types. The inner eccentric shaft is precisely manufactured, allowing customers to adjust the space between the roller and ring die according to their production requirements. It is also easy to install and replace, making it a convenient choice for maintenance and upgrades.

**Notes for Use**
1. Select the appropriate die hole compression ratio.
2. Adjust the working clearance between the ring die and roller properly, ideally between 0.1 to 0.3 mm. (After starting a 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 should be loose at the front and tight at the back. If sharp edges appear on both sides of the roller, use a hand grinder to blunt the flange part for better contact with the ring die.
4. Before feeding raw materials into the pellet mill, perform precleaning 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 cone hole of the ring die guiding material, causing shrinkage, it must be repaired. During repair, ensure that the lowest height of the inner surface of the ring die is at least 2mm higher than the bottom of the overtravel groove. Additionally, the eccentric shaft adjustment must allow for extra space; otherwise, the ring die should be scraped.
