How fine can a ball mill grind powder? Is the finer the better?

The production range of the ball mill produced by XKJGroup is between 0.2-300 tons, and the general feed size requirement is not more than 25mm. Under normal circumstances, its discharge particle size is around 0.074-0.6mm. It is a very efficient grinding and powder making equipment, isn't it better to be finer?

In fact, it is not beneficial to grind the material infinitely fine for selection. Grinding too fine will cause many useful metal minerals to be discharged with water due to the fine particles. This not only reduces the grade and recovery rate of the concentrate, but also does a lot of useless work, increasing the consumption of the ball mill and increasing the grinding cost.

Of course, if the grinding particles are too coarse, it will lead to incomplete separation of metal minerals from the ore, causing the separated substances to not be fully dissociated, which is also not conducive to subsequent sorting operations. Therefore, controlling the fineness within a reasonable range in grinding operations is an important link to improve grinding efficiency and improve mineral processing recovery rate. The staff of the ball mill in the beneficiation plant should attach importance to the grinding operation and the selection of grinding equipment, proficiently master grinding technology, and strictly control the grinding fineness within the suitable scheme of the beneficiation economic indicators.
