  • Optimization of mill performance by using

    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. This is usually performed soon after a crash stop. The basic principle is to measure the height ‘H’ from the charge to the shell and the internal mill ...
