Mathematical modeling of wear rate of

2005-3-1  The cement industry provides high wear environment for many casting units which results in high production costs and consumes both the time and efforts of different available skills to investigate and replace the worn parts. Aims to consider a predictive system for the wear of such units that will reduce the related unpredicted incidents.

how to estimate the wear rate for Ball mill - Page 1 of 10

2009-12-8  With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated. More simply and quite adequate is to keep a record of material ground and of charge added periodically to cover a given level of mill power. By this way you can measure easaly wear of ball/ ton of cement.

2015-11-16  The measured wear rate with hardfaced liners was 0.12 g/T. The 50% reduction in wear rate with hardfaced liners was expected as data from other vertical cement mills indicated such a savings could be expected. In either case the wear rate has exceeded expectations and operation has not been detrimentally effected by wear.
