Roller Cover Material for Ball Press Machines Choosing the Right Ball Pocket Size for Ball Press Machine Rollers

Time：Mar 12,2021

The roller shell of the pellet press is a critical component that plays a vital role in the machine. It is a cylindrical structure with ball-shaped recesses carved into its outer surface, surrounding the core of the pellet press roller. The lifespan of the roller shell directly determines how long the pellet press can operate, as well as the shape and quality of the pellets it produces.

The roller cover materials for the briquetting machine include 65Mn, 9Cr2Mo, and high-chromium alloys. Different materials require different roller covers during compression: 65Mn is the most common, made from cast steel parts with low cost, typically used for pressing materials like coal powder and coke powder; in contrast, the compression rollers made from 9Cr2Mo and high-chromium alloys are forged components, ideal for compacting mineral powders, magnesium powder, and similar materials.
Choosing Roller Groove Dimensions for the Ball Press Machine
The shape and dimensions of the ball recesses on the roller surface of the pelletizing machine can be customized to meet user requirements, offering a wide range of options. Pelletizing machines come in various shapes, including pillow-shaped, semi-cylindrical, egg-shaped, rod-shaped, thin-sheet pill-like, walnut-shaped, apricot-core-like, and even small granule forms, among others.

The dimensions of the ball socket in the pressing machine must not be too large or too small. If it’s too small, the overall pressure generated won’t be sufficient, leading to issues when releasing the ball. On the other hand, if it’s too large, the material’s hardness will decrease, potentially compromising its strength and performance.
Therefore, the ball socket size of the press machine roller cover should be just right—too large or too small can both negatively affect the overall performance of the machine. When placing an order, users should consider multiple factors carefully. For materials with varying hardness levels, it’s essential to select roller covers that match not only the material’s hardness but also its wear resistance. Zhengzhou Hongxin’s press machines are equipped with highly wear-resistant roller covers, which offer convenient ball socket machining and boast an exceptionally long service life.
