**Features of FDSP Roller Shell** 1. Made from wear-resistant alloy raw material, processed with fine and heat treatment. 2. Constructed from bearing steel, high hardness, excellent wear resistance, long service life, available in different tooth depth and shape options. 3. 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 advantage of honeycomb roller shells is even wear on the ring die, although coil performance may be less optimal. 7. Scallop-shaped roller shells offer better coil performance and are widely used in feed mills, though they may cause uneven wear on the ring die. 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:** 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 pellets. Made from wear-resistant alloy steel with carburization heat treatment, it offers even hardness and a long service life. It comes in three types: through-tooth, non-through-tooth, and pass type. Precise inner eccentric shaft dimensions allow for easy adjustment between the roller and ring die based on 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, ideally between 0.1 and 0.3 mm. (After turning on a new pellet mill, the roller will be driven by the ring die but not rotate.) 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 proper contact between the roller and ring die. 4. Before feeding raw materials into the pellet mill, perform pre-cleaning and magnetic separation to reduce iron impurities entering the die holes. Regularly check the die holes for blockage and clean them if necessary. 5. If plastic deformation occurs in the cone hole of the ring die guiding material, 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. Additionally, the eccentric shaft adjustment should allow for some extra space; otherwise, the ring die should be scraped.
