Product Introduction

The press roller liner is the core component of a pelletizing machine, primarily used to compress powdered or granular materials—such as coal powder, mineral powder, fertilizers, and more—into spherical pellets via high-pressure extrusion.

Its performance directly affects forming efficiency, pellet quality, and equipment lifespan. Below is a detailed introduction to the press roller liner:

Function of the ball press roller cover:
- **Molding Function**: Using the recessed die design on the roller surface, loose materials are compressed into specific shapes (such as spherical, ellipsoidal, or cubic forms).
- **Wear-resistant protection**: Shields the press roller core from material friction and high-pressure impacts, extending the equipment's service life.
- **Pressure Regulation**: The structural design of the roller surface influences the distribution of compression pressure, ensuring uniform compaction density during forming.
