Click to chatThe question about modern intelligent information processing methods usage for a ball mill filling level evaluation is considered. Vibration acceleration signal has been measured on a mill laboratory model for that purpose. It is made with accelerometer attached to a mill pin. The conclusion is made that mill filling level can not be measured with the help of such signal amplitude only.

Click to chatThe degree of filling the mill with balls also influences productivity of the mill and milling efficiency. With excessive filling the rising balls collide with falling ones. Generally filling the mill by balls must not exceed 30–35 of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length.

Click to chat· Further tests were conducted in a mill with a 20 ball filling with increasing coarse or fine silica sand particle filling from 0150 at the mill speeds of 63-98 of the critical mill speed.

Click to chat· Usually plant operators use mill power readings as an indicator of ball filling degree and often try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level such as pulp density and liner configuration.
