Optimization of mill performance by using

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. The current way to measure the charge filling degree Crash stops and grind-out Generally, crash stops

Liners protect the outer shell of the mill from wear liners are renewable. 2. Lifters prevent slipping between the medium and slurry charge in the mill and the mill shell. Slippage will consume energy wastefully but more importantly it will reduce the ab ility of the mill shell to transmit energy to the tumbling charge. This energy is required to cause grinding of the material in the mill

Wet Semi-Autogenous Grinding Mills

Analysis of wear patterns on the shell liners showed that most of the wear was taking place at the feed end liner of the mill. At changeout it was observed that there was a considerable amount of steel left on the center and discharge liners. To compensate for this, it was decided to re-design the liners. This design was referred to as the stepped liner profile in that they step down as you go

Wear Tests on Grinding Balls

In our own ball mill grinding oper- ations at Climax, Colo., we were faced with this problem. After we had run a few large scale wear tests at considerable expense we decided to investigate the possibilities of a small scale wear test which would be capa- ble of testing numerous types of balls within a relatively short time. The most important requirement of any test is, of course, that it

The Selection and Design of Mill Liners MillTraj

Liners protect the mill shell from wear and transfer energy to the grinding charge, and a careful balance is required to optimise these conflicting requirements. This review serves to highlight these problems and how they can be tackled in a logical and often inexpensive manner by considering charge trajectories and liner spacing criteria, in conjunction with liner wear monitoring. An overview
