Excess of slurry could also be estimated. To get rid of pulp and rocks in the charge, a mill grind out (no ore feed) of 10 to 20 minutes is also performed before mill inspection or relining. The complete grind out is required to obtain the accurate ball load measurement or the percentage by volume of balls in the mill.
