**Features of FDSP Roller Shell** 1. Made of wear-resistant alloy raw material, processed with fine and heat treatment. 2. Crafted from bearing steel, offering high hardness, excellent wear resistance, long service life, and customizable tooth depth and shape. 3. The tooth surface design enhances pelleting performance. 4. Commonly used tooth forms include honeycomb, scallop shape, and scallop shape with edge banding. 5. Honeycomb and scallop-shaped roller shells are primarily used in livestock and poultry feed pelleting. 6. Honeycomb roller shells ensure even wear on the ring die but may have weaker coil performance. 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 feed from sliding during extrusion. We have a wide range of pellet mill parts in stock, ready for immediate delivery.

**Product Description** Roller shell, commonly known 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 pellet products. Manufactured from wear-resistant alloy steel with carburization heat treatment, it ensures even hardness and a long service life. It comes in different types such as through-tooth, non-through-tooth, and pass-type. The inner eccentric shaft is precisely sized, allowing customers 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 (between 0.1 and 0.3 mm). After turning on the 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 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 for better connection with the ring die. 4. Before feeding raw materials into the pellet mill, perform precleaning and magnetic separation to reduce iron impurities entering the die holes. Regularly check the die holes for blockage and clean them as needed. 5. If plastic deformation occurs in the ring die’s guiding cone hole, causing hole shrinkage, repair it immediately. During repairs, ensure that the lowest height of the ring die’s inner surface is 2mm higher than the bottom of the overtravel groove. Additionally, the eccentric shaft adjustment must allow for extra clearance; otherwise, the ring die should be scraped.
