Description

Roller Shell plays a crucial role in compressing and shaping raw materials into pellets. It is installed inside the pellet die and rotates around an eccentric shaft.

As one of the most critical components in the pellet mill, the roller is constantly subjected to friction and pressure – causing it to wear out nearly twice as fast as the die. That’s why choosing a high-quality roller is essential: it helps reduce production costs, maintain efficiency, and ensure consistent product quality.

At TIEN PHAT, we supply premium dies, replacement parts, and machine components to leading animal feed and aquafeed producers in Vietnam and multinational corporations around the world—helping them achieve greater durability and performance in every production cycle.

Manufacture Process

Materials

We manufacture all pellet mill rollers using premium-grade steel, engineered with high precision to suit every dimension and all pellet mill models on the market.

Hobbing

Each roller is CNC-machined with fully automated equipment, ensuring precise and consistent tooth profile geometry across the entire surface.

Heat Treatment

We apply high-temperature heat treatment technology to enhance the product’s wear resistance and ensure uniform internal hardness. After treatment, each roller achieves an average hardness of HRC 58–59.
