### **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. Available in various tooth depths and shapes to suit different needs.
3. The tooth surface design enhances pelleting performance and ensures consistent quality.
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 provide 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 the feed from sliding during extrusion.
We have a wide range of pellet mill parts in stock, ready for immediate delivery.

### **Product Description**
A roller shell, commonly referred to as a 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. The roller shell is made from wear-resistant alloy steel with carburization heat treatment, ensuring even hardness and a long service life. It comes in three main types: tooth-through, tooth-no-through, and pass type. The inner eccentric shaft is precisely manufactured, allowing for easy adjustment of the space between the roller and the ring die according to production requirements. Additionally, it is designed for simple installation and replacement.

### **Important Notes**
1. Choose the correct die hole compression ratio based on the material being processed.
2. Adjust the working clearance between the ring die and the roller properly (between 0.1 and 0.3 mm). After starting the pellet mill, the roller should be in a pre-running state without rotating.
3. New ring dies should be paired 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 pre-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, causing shrinkage, repair it immediately. During repairs, ensure that the lowest point of the inner surface of the ring die is at least 2mm higher than the bottom of the overtravel groove. Also, make sure the eccentric shaft adjustment allows for extra space; otherwise, the ring die may need to be scrapped.
