CE Approved Wear Parts Roller and Roller Shell for Pellet Mill Machine
**Product Overview**
The roller shell is one of the most essential working components in a pellet mill, used for processing various types of biomass fuel granules, animal feed pellets, and other pellet products. It is manufactured from wear-resistant alloy steel with carburization heat treatment, ensuring even hardness and an extended service life. The roller shell comes in different types such as tooth-through, tooth-no-through, and pass type, allowing flexibility based on the application requirements.
Key features include precise dimensions of rolling parts like the inner eccentric shaft, which facilitate space adjustment between the roller and ring die according to production needs. The design also ensures ease of installation and replacement.
**Key Features of Roller Shell**
1. Made from wear-resistant alloy materials and processed with fine machining and heat treatment.
2. Constructed from bearing steel, offering high hardness, excellent wear resistance, and 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 shape with edge banding.
5. Honeycomb and scallop-shaped roller shells are primarily used in livestock and poultry feed pelleting.
6. Honeycomb-shaped roller shells ensure even wear on the ring die but may have less 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-shaped with edge banding is ideal for aqua feed, preventing material from sliding during extrusion.

**Different Patterns of Roller Shell**
Roller shells come in various designs, each suited for different applications. Common types include:
- **Open Ends Corrugated**: Dimpled and oblique-shaped roller shells
- **Closed Ends Corrugated**: Honeycomb-shaped and fluted-shaped roller shells
Corrugated and dimpled roller shells are widely used in the livestock, poultry feed, and biomass pelleting industries.
**Why Choose Us?**
Maintenance is crucial for any machine after prolonged use. The roller shell is a critical component in pellet mills, responsible for processing a variety of materials including biomass, feed, and wood pellets.
As a professional manufacturer with over 20 years of experience, we specialize in producing high-quality roller shells and other pellet mill spare parts such as ring dies, bearings, and shafts. Our products are known for their high abrasion and corrosion resistance, ensuring a long service life.
Our roller shells are suitable for both feed pelleting and fuel pelleting industries. We use premium bearing steel, alloy steel, or carbon steel to manufacture these components. The working area of the roller shell ranges from 60mm to 300mm, while the diameter of the pellet roll/shell varies from 110mm to 450mm, with hardness reaching up to HRC 58–62.
**Key Dimensions:**
- **I.D.** – Inner Diameter: The most commonly specified dimension for the roller shell, often determined during die selection.
- **O.D.** – Outer Diameter: The overall diameter of the roller shell.
- **W** – Width of the roller shell.
Our ring dies and roller shells are sold globally, and we can produce custom roller shells based on customer drawings. We provide all the necessary parts to keep your equipment running smoothly.
