In order to give some useful suggestions on ball mill usage, here we analyze the factors affecting the production efficiency, hoping to produce help and support to customers. As for rotating speed control, the high-efficiency production is very limited. And only if you control the rotating speed well can you control the consumption of steel ball.
When the rotating speed of ball mill is high, the height the ball raised is high. The ball will get away from the barrel when the ball rises to certain height, and falls along the parabolic path. There is comparatively large impact force on drop point. When the ore is crushed by the impact force, the grinding effect is highest. When the rotating speed of ball mill exceeds a certain speed, the steel ball will rotate with the barrel and won’t fall down, in a condition of centrifugal movement. There is no impact force, so the grinding function is much less, and the ball mill stop grinding.
So in the production of ball mill, to control the critical rotating speed reasonably can realize the effective control on the steel ball consumption. Meanwhile the lower on ball consumption will decrease the ore grinding production cost. After all, control the ball mill rotating speed perfectly will greatly improve the ball mill production efficiency and decrease the energy consumption of ball mill.
