Grinding Media & Lining Media Liner Wear Rate Modelling

The cost of replacement of the metal worn from the working surfaces of the balls and liners of a mill often represents a considerable fraction of the cost of operation of the plant and so is of some real economical importance. In spite of this importance, however, the amount of information in available on this subject is amazingly small and, unfortunately, is insufficient to form the basis of

A new predictive model of lifter bar wear in mills

Dec 01, 2010 Predicting the rate of liner wear helps to correctly time the replacement of worn liners and thus facilitates the scheduling of preventative maintenance of the mill. As liners are very costly, one of the main goals set for the manufacturers by users is to increase the life of liners.

Optimization of mill performance by using

As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. (plan a liner change and/or change mill speed if possible).

Optimise SAG mill capacity and avoid

Optimising the capacity of your SAG mill is crucial to avoiding downtime and liner wear and damage. With variances in mill ore feed rate, mill speed and slurry density, critical impacts can occur in your SAG mill. The speed at which these variances are adjusted for is thus crucial for minimizing damage and optimizing liner life.

How do I track the Mill Liner state? IntelliSense.io

The Grinding Application's Liner Wear Model tracks the state of the liners and lifters in the SAG or Ball Mill, by modelling the decrease in lifter height and angle across different liner sections in real-time. The model uses historical information/data about liner wear to relate the wear rate with mill throughput and operating regimes.

One month after the ball mill was put into operation, the mill liners and step liner of the first bin was broken frequently. At most, 18 pieces were broken in one week, which needs to be replaced. At most, 18 pieces were broken in one week, which needs to be replaced.

Predicting Liner Wear in a SAG Mill using Rocky DEM

Mining companies can realize significant cost savings simply by slowing peak wear rate without compromising throughput, an outcome that calls for optimizing both the liner design and operating process parameters. Likewise, changes to the mill lifter design and/or its operation can result in reduced power draw and therefore energy costs.

Composite PulpMax™ mill liners can lower costs and improve

This means that the liners also need to be wear and tear resistant and easy, fast and safe to replace. The mill liner handler machines, designed to cantilever inside of a mill chamber during a liner change out, have limitations based on the weight of the liner components to be manipulated in place.
