In the actual production process if the ball mill has too many balls the steel balls are easily overlapped with each other the grinding effect is lost and a part of the steel balls can not be lifted at all so that the grinding capacity is reduced and meanwhile the power consumption of the ball mill is increased; If the ball mill is too ...

Reasonable filling rate. When the speed of the ball mill is certain the filling rate is large the steel ball hits the material more times the grinding area is large the grinding effect is strong but the power consumption is also large and the filling rate is too high it is easy to change the movement state of the steel ball and reduce ...

The power consumption is usually determined by charge fill level lifter height lifter number and mill speed. However almost all of the classical theories for calculating the power consumption of ball mills disregard the effect of lifters and only focus on rotation rate charge fill level as well as size and shape of grinding media thereby ...

United States power consumption is related to comminution Comminution and Energy Consumption 1981. With this in I mind it is understandable that one would want to control a grinding circuit so that the energy required to process a given ton of ore is optimal. .Furthermore overgrinding an ore and the subsequent production of fines can reduce the
