Our PERI™ AutoCharge Mill Grinding Ball Charging System will allow you to leave inefficient bulk charging practices behind. Our system will ensure your mill operates at optimum charge level to save on energy and improve performance. When charging a grinding mill, the standard practice is to dump tons of balls into the mill at once and replace.

The performance of tumbling mills is sensitive to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to contin- uously optimize mill operation, it is vital to obtain regular measurements of the ball load and pulp position.
