Jul 18, 2016· Results of the optimization can be measured by multiple parameters such as separator efficiency, specific power consumption, system throughput, and wear rate of grinding media and liners. Changing the separator to a high efficiency type brings about .
Abstract: The specific power consumption, product quality and other performance of the "OK" and "CK" vertical roller mills for cement grinding are briefly stated. Hence These include: (a) restoring a table liner and roller tires by hard-facing to reduce maintenance costs; (b) increasing the air flow rate through the roller mill to
Formula to calculate grinding media wear rate for cement . A cement grinding mill A with a capacity of 50 tons per hours utilizes forged steel grinding balls costing P12 000 per ton which have a wear rate of 100 grams per ton cement milled Another cement mill B if the same capacity uses high chrome steel grinding bans costing P30 000 per ton with wear rate of 10 grams per ton cement milled
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.
