**Features of FDSP Roller Shell**
1. Made from wear-resistant alloy raw material, processed with fine and heat treatment.
2. Crafted from bearing steel, offering high hardness, excellent wear resistance, and a long service life. Custom tooth depth and shape available.
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 mainly used in livestock and poultry feed pelleting.
6. Honeycomb roller shells ensure even wear on the ring die but have weaker coil performance.
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 the feed from sliding sideways during extrusion.
We have a large stock of pellet mill parts available for immediate delivery.
**Product Description:**
Roller shell, commonly referred to as a roller, is one of the key working 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 features uniform hardness and an extended 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 according to production needs. The product is also easy to install and replace.

**Important Notes:**
1. Choose the appropriate die hole compression ratio.
2. Adjust the working 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-running 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 part for better alignment.
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 guide material, causing hole shrinkage, it must be repaired. During repair, ensure that the inner surface of the ring die is at least 2mm higher than the bottom of the overtravel groove. Additionally, eccentric shaft adjustments should allow extra space; otherwise, the ring die should be scraped.
