Ball mill's low grinding efficiency, low processing capacity, high production energy consumption, unstable product fineness, etc. are problems that many customers will encounter. How to effectively improve the grinding efficiency of the ball mill is an important issue. Now, let's share 10 ways to improve the grinding efficiency of the ball mill!

The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet. The proportion of the mill-exit material returned ...
