Roller Shell for Ring Die Pellet Mill (SZLH 420-120)

**Roller Shell – Pellet Mill Roller Shells for Sale** **Features of FDSP Roller Shell** 1. Made from wear-resistant alloy material, processed through fine and heat treatment. 2. Crafted from bearing steel, high hardness, excellent wear resistance, long service life, with various tooth depth and shape options. 3. The tooth surface design enhances 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 production. 6. Honeycomb roller shells ensure even wear on the ring die but have poor coil performance. 7. Scallop-shaped roller shells offer 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 material 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 to process various types of biomass fuel granules, animal feed pellets, and other pellet products. Made from wear-resistant alloy steel with carburization heat treatment, it offers uniform hardness and a long service life. It comes in different types such as tooth-through, tooth-no-through, and pass type. Components like the inner eccentric shaft are precisely manufactured, allowing customers to adjust the space between the roller and the ring die according to their production needs. It is also easy to install and replace. **Product Photos:** [Insert product images here] **Notes for Use:** 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 starting a new pellet mill, the roller is driven by the ring die and enters a pre-running state without rotating.) 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 sharp corners appear on both sides of the roller, use a hand grinder to blunt the flange part to ensure proper connection. 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 if necessary. 5. If plastic deformation occurs in the ring die guiding cone hole, causing hole shrinkage, repair is required. 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 must allow for extra space; otherwise, the ring die should be scraped. Our roller shells are designed for durability, efficiency, and compatibility with major pellet mill brands. Whether you're running a feed mill, biomass plant, or any other pellet production line, we have the right solution for you. Contact us today for more details and competitive pricing.
