**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 a long service life. Available in different tooth depths and shapes.
3. The tooth surface design enhances pelleting performance.
4. Common 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. Honeycomb roller shells ensure even wear on the ring die but may have weaker coil performance.
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 large stock of pellet mill parts available for immediate delivery.

**Product Description:**
The roller shell, commonly known as the roller, is one of the key components in a pellet mill. It is used to process 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 three types: tooth-through, non-tooth-through, and pass type. The inner eccentric shaft is precisely machined, allowing customers to adjust the space between the roller and ring die according to their production needs. The design also makes installation and replacement easy and efficient.

**Important Notes:**
1. Select the appropriate die hole compression ratio.
2. Adjust the working clearance between the ring die and roller (0.1–0.3 mm is suitable). After starting 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 when connected to the ring die. If sharp corners appear on both sides of the roller, use a hand grinder to blunt the flange part for better alignment.
4. Before feeding raw materials into the pellet mill, perform preliminary 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 shrinkage, repair it immediately. During the repair, ensure that the lowest height of the inner surface of the ring die is 2mm higher than the bottom of the overtravel groove. Also, make sure the eccentric shaft adjustment allows for extra space; otherwise, the ring die should be scraped.
