Rate of balls in cement mills. Cement Kilns Size Reduction and Grinding. As has been discussed, mills that rely upon sieves for their fineness control may be suitable for rawmix or coal grinding, but for cement, particles leave the mill as soon as they are just fine enough to pass the sieve, and the ultra-fines needed for cement strength are not produced in quantity.

Dec 08, 2009018332Re 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.
A cement grinding mill quotAquot 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 quotBquot 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.

Significant variation of balls filling degree. 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. A direct measurement of the ball level in the mill.
The cement clinker grinding circuit reduces the feed from 80 passing size between 10 and 20 mm to 100 passing 90 microns. The size reduction takes place in a two- compartment tube mill the first compartment of the mill is shorter than the second compartment. The coarse clinker is ground in the first compartment where larger balls.

Nov 18, 2010018332Apart from use in cement plants, in other countries, for example England, dedicated MBM incinerators are used. The feeding rates of MBM in cement kilns vary from country to country, in Spain the limit is 15 percent of the energy needed in the kilns Conesa et al., 2005. However, the limit in the feed rate of MBM is due to the effects of chlorides.
