Knowledge on troubleshooting faults during the operation of mineral powder balling machines

Time：Jun 28,2021

The mineral powder ball press machine is a derivative piece of equipment in our metallurgical machinery industry. Due to its widespread application in the metallurgy sector, it enjoys relatively broad usage within the industry. Primarily, this equipment is designed to compress powdered materials into shaped pellets. Its advancement, however, is closely tied to the growth of the metallurgical industry—after all, only when the metallurgical sector itself reaches new heights of prosperity can the future prospects for our ball press machines truly become limitless.

When a mineral powder balling machine is used to compress materials, it’s often affected by other components of the equipment. This is mainly because parts directly involved in the material-compression process can disrupt the shape of the spherical pellets being formed. For instance, if the machine doesn’t generate sufficient pressure, excess powdered material tends to accumulate. Additionally, the adjustment of the roller covering—another critical component closely tied to material compression—is essential. Only when the roller covering meets quality standards and remains undamaged can the machine consistently produce high-quality, stable spherical pellets. Moreover, design flaws in the balling machine itself may also compromise the shaping process. Common issues arise from improper design of the ball cups, such as excessively deep cup formations, which make it difficult for the pellets to release smoothly. Another potential problem stems from inadequate surface finishing during the manufacturing of the roller covering, leading to uneven contact with the material. On the material side, factors like improper particle size or insufficiently uniform mixing can further degrade the balling process. Even the choice and distribution of binders during mixing can significantly impact the final quality of the formed pellets.

In summary, the demolding of materials in a mineral powder ball press is influenced by multiple factors—primarily the properties of the material itself, as well as the performance of the equipment. After all, our ultimate goal is to produce qualified, well-formed material pellets, which is exactly what we need. Therefore, ensuring optimal demolding performance in the coal-based pellet press is crucial.
