This article will show you 4 things you need to know about roller shells.
1. What is Roller shells
Roller shells is also called pellet mill roller shell, it is a specialized component that is used in the production of pellets from raw materials such as wood, feed, and other biomass sources.The roller shell is a key component of a pellet mill, as it helps to compress and shape the raw material into small, dense pellets.
2. The Composition of the Roller Shells
The composition of a pellet mill roller shell can vary depending on the manufacturer and the specific application for which it is intended. In general, however, roller shells are typically made of a strong and durable material such as steel, which provides the necessary strength and durability to withstand the high pressure and heat generated during the pelletizing process. The surface of the roller shell is often coated with a wear-resistant material such as chrome or tungsten carbide to improve its durability and lifespan. Some roller shells may also have a hardening treatment applied to further improve their wear resistance. Additionally, some roller shells may have a smooth surface, while others may have a patterned or textured surface to improve their performance in specific applications.
3. Types of Roller Shells
There are several different types of pellet mill roller shells available on the market, each designed to suit specific applications and requirements. Some common types of roller shells include:
Smooth roller shells:
These roller shells have a smooth surface and are typically used in the production of feed pellets, where a smooth surface is desired to produce a uniform and high-quality product.
Corrugated roller shells:
These roller shells have a patterned or corrugated surface, which helps to improve the durability and lifespan of the roller shell. They are often used in the production of wood pellets, where the corrugated surface helps to better grip the raw material and improve the pelletizing process.
Grooved roller shells:
These roller shells have a series of grooves or channels on their surface, which helps to improve the flow of the raw material through the pellet mill. They are commonly used in the production of feed and biomass pellets.
Tungsten carbide coated roller shells:
These roller shells have a tungsten carbide coating on their surface, which provides excellent wear resistance and a long lifespan. They are often used in high-production environments where the roller shells are subjected to heavy use.
Chrome coated roller shells:
These roller shells have a chrome coating on their surface, which helps to improve their wear resistance and lifespan. They are commonly used in the production of feed and biomass pellets.
4. How to Use Roller Shells
Pellet mill roller shells are used in pellet mills, which are machines that are used to process raw materials such as wood, feed, and other biomass sources into small, dense pellets. The roller shells are a key component of the pellet mill, as they help to compress and shape the raw material into pellets.
To use roller shells in a pellet mill, the roller shells must first be installed on the pellet mill. This typically involves mounting the roller shells on the shafts of the pellet mill, and securing them in place with bolts or other fasteners. Once the roller shells are installed, the pellet mill can be loaded with the raw material to be processed. The raw material is fed into the pellet mill through the hopper, and as it passes through the pellet mill, it is compressed and shaped by the roller shells into small, dense pellets. The finished pellets are then discharged from the pellet mill and can be used for a variety of applications such as animal feed, fuel, or fertilizers.
