Ball Mill Liner Wear Rate

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

(PDF) The Influence of Liner Wear on Milling Efficiency

liners to obtain liner shape, ball size distribution, liner volume and liner mass (suite d for load cell calibration) and ball/ore charge volume information. Th e survey protocol is given in Table 1.

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).

High Chrome/Moly Iron Liners > 600 700 BHN Cr iron- rod mills and ball mills > Excellent abrasion resistance. Provide the best combination of toughness and abrasion resistance among white cast irons. The tradeoff is between wear resistance and toughness > Two types: the hard, discontinuous, X7C3 eutectic carbides present in the

Discrete element method modelling of liner wear in dry

mill liner profiles Valderrama et al. (1996) performed tests of measurement of the wear of lifters in a laboratory ball mill. The object of those tests was to study the role of cascading and cataracting motion of balls on the wear of liners. They used a mill having a diameter of 0.28 m and a length of 0.11 m. The mill
