5 Ways to Improve the Ball Mill Efficiency Fote Machinery(FTM)

The researches show that the ball mill efficiency is also related to the feeding size. The larger the feed size, the longer the time needed to grind the material to needed fineness, the more power consumption, and the lower the efficiency. The crushing efficiency is higher than the grinding efficiency, so a crusher can be equipped before grinding.
