**Features of FDSP Roller Shell**
1. Made of 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. Tooth depth and shape can be customized.
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 types are primarily 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, though they may cause uneven die wear.
8. Scallop shape with edge banding is ideal for aqua feed, preventing feed from sliding during extrusion.
We have a wide range of pellet mill parts in stock.
**Product Description:**
The roller shell, commonly known as the roller, is one of the key working components in a pellet mill. It is used to process various types of biomass fuel granules, animal feed pellets, and other types of 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, including tooth-through, tooth-no-through, and pass types. Components like the inner eccentric shaft are precisely manufactured, allowing users to adjust the space between the roller and ring die according to production needs. The product is easy to install and replace.

**Notice:**
1. Select the correct die hole compression ratio.
2. Adjust the working clearance between the ring die and roller (between 0.1 and 0.3 mm). After turning on 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 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 contact between the roller and die.
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 if necessary.
5. If plastic deformation occurs in the ring die’s guiding cone hole, causing shrinkage, it must be repaired. During repair, ensure that the lowest height of the ring die’s 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.
