CE Approved Wear Parts Roller and Roller Shell for Pellet Mill Machine
Product Overview:
The roller shell is one of the essential components in a pellet mill, used for processing various types of biomass fuel granules, animal feed pellets, and other pellet products. It is made from wear-resistant alloy steel with carburization heat treatment, ensuring even hardness and long service life. The roller shells are available in different types such as through-tooth, non-through tooth, and pass type. The precise dimensions of rolling parts like the inner eccentric shaft allow customers to easily adjust the space between the roller and ring die according to production needs. They are also easy to install and replace.
Key Features:
1. Made from high-quality wear-resistant alloy materials, processed with fine machining and heat treatment.
2. Crafted 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 patterns include honeycomb, scallop shape, and scallop with edge banding.
5. Honeycomb and scallop-shaped roller shells are widely used in livestock and poultry feed pelleting.
6. Honeycomb roller shells provide even wear on the ring die but may have poor coil performance.
7. Scallop-shaped roller shells offer good coil performance and are commonly used in feed mills, though 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.

Types of Roller Shells:
There are multiple types of roller shells available, each designed for specific applications:
- Open Ends Corrugated: Dimpled and oblique-shaped roller shell
- Closed Ends Corrugated: Honeycomb-shaped and fluted-shaped roller shell
Corrugated and dimpled roller shells are among the most commonly used in the feed and biomass pellet industries.
Why Choose Us?
Maintenance is essential for any machine after prolonged use. The pellet mill roller shell is a critical working component used to process various types of biomass fuel, 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 can be used in both the feed and fuel pellet industries. We use premium-grade bearing steel, alloy steel, or carbon steel to manufacture them. The working area of the roller shell ranges from 60mm to 300mm, while the diameter of the pellet roll/shell ranges from 110mm to 450mm, with a hardness of HRC 58-62.
Understanding the key dimensions:
- I.D. = Inner Diameter of Roller Shell: This is the most common dimension specified during die selection.
- O.D. = Overall Diameter of Roller Shell: The diameter of the pellet roll/shell
- W = Width of 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.
