Mill Bolting
The mill manufacturer specifies a load which is designed to be the optimum load applied to the bolts to hold the mill together for its entire life, which can be in excess of 20 years, some mill manufacturers specify an elongation, unfortunately they usually specify a torque figure which should in a best case produce the correct elongation, but rarely does.
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
