**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 long service life. Various tooth depths and shapes are available.
3. The tooth surface design enhances pelleting performance.
4. Common 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 production.
6. The honeycomb roller shell ensures even wear on the ring die but has poor coil performance.
7. Scallop-shaped roller shells provide good 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 during extrusion.
We have a wide range of pellet mill parts in stock.
**Product Description**
The roller shell, commonly referred to as the 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 pellets. Made from wear-resistant alloy steel with carburization heat treatment, it offers even hardness and a long service life. It comes in different types such as through-tooth, non-through-tooth, and pass-type. The inner eccentric shaft is precisely manufactured, allowing users to adjust the space between the roller and ring die according to their production needs. The design also makes it 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 properly (between 0.1 and 0.3 mm). After starting 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 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 to ensure a proper connection.
4. Before feeding raw materials into the pellet mill, perform 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 hole shrinkage, it must be repaired. During repair, ensure that the lowest height of the ring die inner surface is 2mm higher than the bottom of the overtravel groove. Also, make sure the eccentric shaft adjustment allows for extra space; otherwise, the ring die should be scraped.
