FL told IM: "Extending the life and availability of mill liners is crucial. Weighing up to 4 t a piece, mill liners require a lot of effort to replace when they are worn out, and SAG mill downtime can be around $130,000/h, while lead times can span months. Overall it can cost well over $1 million dollars for a liner .
Our ball mill liners are the result of state-of-the-art software-driven designs with industry-leading inspection data, achieving an optimal charge trajectory and rate of wear life for your ball mill. We ensure your ball mill liners are fitted with precise levels of workmanship, facilitating maximum mill uptime for increased production.
For comparison, the power intensity of a ball mill is about 20 kW/m 3. This high power intensity allows the IsaMill to produce fine particles at a high throughput rate. The high power intensity of the IsaMill comes from its high stirring speed of about 20 meters per second ("m/s").
Vertical roller mills Vs ball mills has long been a raging debate in the cement industry. In spite of the fact that vertical roller mills have been around for over ten years now and have gradually become the standard as far as cement manufacturing goes, several cement manufacturers still prefer ball mills for cement production [.]

Mill HEAD LINERS. Head liners are of the segmental type constructed of Manganese Steel, Chrome molybdenum, or Ni-Hard and are designed to pass easily through the manhole opening or discharge opening in the case of rod mills. For ball mill work ribs are cast with the feed head liners to deflect the ball mass and minimize wear on the headliner ...

mill media wear rates from laboratory based ball mill tests [8]. It was shown that laboratory mill tests could predict plant media wear rate to within 20%. Whilst this is still a wide margin of error, this variant of the BMA test shows promise. The BMA test is non-standardised in the sense that the reference used is the average wear rate of all ...

Tega DynaWear. Tega Mill Linings provide optimal grinding solutions in major mineral processing plants all over the world. Tega rubber lining system is the preferred lining system for secondary ball mills; regrind mills, rod mills and scrubbers.
Mill liners fill a basic role: to protect your mills from the intense wear and tear that comes from grinding down hard, raw materials. But even if they all do the same job, not all mill liners are created equal. From the abrasion resistance of rubber to the impact resistance of steel, different material parts offer different advantages. FL supplies the full range of mill liners options ...

The wear rate on rubber mill liners (in fact most if not all types of liners) is a function of ore type and PSD, media type and size distribution, mill filling level, speed and operational up-time. I am not aware of a universal formulation to calculate expected wear life.
In a Ball Mill (particularly) the wear rate or wear life of Rubber depends much on the Ball Size/Diameter used in that mill. The grinding media size which itself is much of a function of the ore/material P80 feed size into that mill. The other primary and addition factor contributing to a mill rubber liner wear is the RPM at which you operate the mill at.
C = factor for mill speed expressed as a percentage of mill critical speed. L = length of grinding chamber measured between head liners at the junction of the shell and head liners. 2.4 Excessive wear of Liners Overcharging of grinding media has also been seen to been a cause of excessive wear of liners inside ball .
