The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23% ...

Mill Filling Tool Dashboard. The new Mill Filling Prediction (MFP) tool is a soft sensor (a mathematical model that act as a sensor) to provide information about the mill's contents and enable it to be controlled closer to its maximum capacity. The MFP tool is developed by Dr Marko Hilden, a Senior Researcher at JKMRC.

Discrete element method (DEM) modelling has been used to systematically study the effects of changes in mill operating parameters and particle properties on the charge shape and power draw of a 5-m ball mill. Specifically, changes in charge fill level, lifter shape (either by design or wear) and lifter pattern are analysed.

The method of monitoring the level of filling of a ball mill which is fed with material to be pulverized and is provided with a drum mounted to rotate on two bearings which are relatively far apart, consists in measuring the weight of the drum using strain gauge weight sensors (11-16) under the bearings supporting the drum of the ball mill and comparing the measured weight to …
