Roller Shell for Pellet Press

Roller Shell – Pellet Mill Roller Shells for Sale **Features of FDSP Roller Shell** 1. Made from wear-resistant alloy material, processed through fine machining 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 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 provide 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 the 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 main working parts 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 features uniform hardness and a long service life. It comes in different types, including tooth-through, tooth-no-through, and pass types. The precision of rolling parts like the inner eccentric shaft allows customers to adjust the space between the roller and ring die according to production needs. It is also easy to install and replace. **Product Photos** [Insert product images here] **Important Notes** 1. Choose the correct die hole compression ratio. 2. Adjust the working clearance between the ring die and roller properly, ideally between 0.1 and 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 paired with new rollers. The roller connection with the ring die should be loose at the front and tight at the back. If the roller’s edges become sharp, use a hand grinder to blunt the flange part for better connection. 4. Before feeding raw materials into the pellet mill, perform pre-cleaning and magnetic separation to reduce iron impurities entering the die hole. Regularly check the die holes for blockages and clean them if necessary. 5. If plastic deformation occurs in the ring die guiding cone hole, causing shrinkage, repair it immediately. During repair, ensure that the lowest point 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 clearance; otherwise, the ring die should be scraped. We offer high-quality replacement parts for all major pellet mill brands, ensuring smooth operation and long-lasting performance. Whether you're running a feed mill, biomass plant, or any other pellet production facility, our roller shells are designed to meet your needs.
