**Features of FDSP Roller Shell**
1. Made from wear-resistant alloy material, processed with precision 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. The honeycomb roller shell ensures even wear on the ring die but has weaker coil performance.
7. The scallop-shaped roller shell provides better coil performance and is widely used in feed mills, though it 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, commonly referred to as the roller, is one of the main 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 offers uniform hardness and an extended service life. It comes in three types: through-tooth, non-through-tooth, and pass-type. The inner eccentric shaft is precisely manufactured, allowing customers to adjust the space between the roller and ring die according to their production needs. It is also easy to install and replace.

**Notice**
1. Select the appropriate die hole compression ratio.
2. Adjust the working clearance between the ring die and roller properly (0.1–0.3 mm is recommended). After turning on the 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 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 to ensure proper alignment.
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 the die holes for blockages and clean them as needed.
5. If plastic deformation occurs in the ring die's guiding cone hole, causing hole shrinkage, repair is necessary. During repairs, ensure that the lowest height of the ring die’s inner surface is 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.
