Difference Between Roller Shells and Die Sets

Sep. 07, 2024

What Are Roller Shells and How Do They Function?

BOBSHELL, a leading roller shell manufacturer, specializes in producing high-quality roller shells for various industrial applications. Roller shells are cylindrical components used primarily in pellet mills, where they play a critical role in compressing raw materials into pellets. They work by rotating around a central axis, applying pressure to materials against a die to shape them into specific forms, such as pellets used in industries like feed production, biomass, and pharmaceuticals.

The primary advantage of roller shells is their durability and efficiency in high-pressure environments. At BOBSHELL, our R&D team focuses on creating roller shells that are engineered for long-term use, ensuring that they withstand continuous wear and tear. Our roller shells are customizable through our OEM/ODM services, allowing clients to select materials and specifications that best suit their production needs, ensuring optimal cost performance.

How Do Die Sets Differ from Roller Shells?

Die sets, while used in conjunction with roller shells, serve a different function in the manufacturing process. In pellet mills, die sets are flat or cylindrical plates with perforated holes that determine the size and shape of the final product. Unlike roller shells, which apply pressure to the materials, die sets shape the material as it passes through the holes under the force of the roller shell. Die sets play a crucial role in defining the quality, density, and consistency of the final pellet.

While both roller shells and die sets are critical components in pelletizing processes, the key difference lies in their function—roller shells exert pressure, while die sets shape the material. BOBSHELL specializes in manufacturing both roller shells and die sets, offering clients comprehensive solutions for their production lines. Our factory in China is equipped to manufacture durable die sets that meet the highest standards, offering superior cost performance for wholesalers, factories, and distributors.
