**Features of FDSP Roller Shell**
1. Made from wear-resistant alloy material, processed through fine and heat treatment.
2. Crafted from bearing steel, offering high hardness, excellent wear resistance, and long service life. Custom tooth depth and shape available.
3. The tooth surface design enhances pelleting performance.
4. Common tooth forms include honeycomb, scallop, and scallop with edge banding.
5. Honeycomb and scallop types are mainly 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 offer better coil performance and are widely used in feed mills, though they may cause uneven die wear.
8. Scallop with edge banding is ideal for aqua feed, preventing material from sliding during extrusion.
We have a large inventory of pellet mill parts available for immediate delivery.
**Product Description**
Roller shell, also known as 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 pellet products. Made from wear-resistant alloy steel with carburization heat treatment, it ensures even hardness and a long service life. It comes in different types such as through-tooth, non-through-tooth, and pass type. Precise dimensions of rolling parts like the inner eccentric shaft allow customers to adjust the space between the roller and ring die according to their production needs. Easy to install and replace, this component is essential for efficient pellet production.

**Notice**
1. Select the appropriate die hole compression ratio.
2. Adjust the working clearance between the ring die and roller (between 0.1 to 0.3 mm is suitable). After turning on a new pellet mill, the roller will be driven by the ring die and enter a pre-running state without rotating.
3. New ring dies should be used with new rollers. The roller connection with the ring die 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 pre-cleaning and magnetic separation to reduce iron impurities entering the die hole. Regularly check the die hole for blockages and clean them if necessary.
5. If plastic deformation occurs in the ring die guiding material cone hole, causing the hole to shrink, repair it immediately. During repairs, ensure 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.
