Apr 29, 2017 Recapitulation of Ball Wear Formulas. Nw = number of balls added in time T to compensate for the ball wear. Nt = total number of balls in the mill. N’t = total number of balls in any interval. N1, N2, N3, etc. = number of balls in the first, second, third, etc., intervals. D = diameter of any ball

Dec 08, 2009 Re: how to estimate the wear rate for Ball mill. Hey; Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. 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.

Nov 16, 2015 The actual wear rate for both the roller and table liners before hardfacing was 0.30 g/T. 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

Jul 10, 2019 Ball mill is an important equipment for the preparation of various powder materials in metallurgy, mineral processing, building materials, chemical industry, power generation, ceramics and other industrial departments. The inner surface of the ball mill cylinder is generally equipped with various shapes of liner. Liner is the main vulnerable part of ball mill, and its use cost is about 2%

Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.
