**Features of FDSP Roller Shell** 1. Made from wear-resistant alloy material, processed with fine machining and heat treatment. 2. Crafted from bearing steel, offering high hardness, excellent wear resistance, and a long service life. Available in different tooth depths and shapes upon request. 3. The tooth surface design enhances the 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. The advantage of honeycomb roller shells is even wear on the ring die, although their coil performance is not ideal. 7. Scallop-shaped roller shells offer better coil performance and are widely used in feed mills, but they may cause uneven wear on the ring die. 8. Scallop shape with edge banding is suitable for aqua feed. It prevents feed from sliding to both sides during extrusion. We have a large stock of pellet mill parts available for immediate delivery.

**Product Description:** A 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. The roller shell is made from wear-resistant alloy steel with carburization heat treatment, ensuring even hardness and an extended 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. It is also easy to install and replace.

**Important Notes:** 1. Select the appropriate die hole compression ratio. 2. Adjust the working clearance between the ring die and roller properly, ideally between 0.1 to 0.3 mm. (After starting the new pellet mill, the roller is driven by the ring die but does not rotate.) 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 the two sides of the roller develop sharp corners, 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 guiding material, causing the hole to shrink, it must be repaired. During repair, ensure that the lowest point of the ring die inner surface is at least 2mm higher than the bottom of the overtravel groove. Additionally, the eccentric shaft adjustment should allow for extra space; otherwise, the ring die should be scraped.
