Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing, one example being the Sepro tyre drive Grinding Mill. Industrial ball mills can be as large as 8.5 m (28 ft) in diameter with a 22 MW motor, [4] drawing approximately 0.0011% of the total worlds power (see List of countries by electricity consumption ).

The effects of grinding media shapes on the …

01.02.2013 · The effect of the media shape on grinding kinetics of cement clinker in a ball mill was investigated. Results indicated that cement clinkers obey first-order breakage kinetics in the case of both balls and cylinders. The specific rate of breakage provided by cylinders is higher than that of balls. The results also showed that − 2.00 + 1.70 mm is an optimum feed size for 20 mm diameter balls ...

distribution, thus obtaining a finer and better performing cement. Grinding aids act at two levels: in the mill, with the reduction of cement coating on grinding media and mill lining, and in the separator, with the improvement of classification process. Detailed description of the use of grinding aids in cement industry is reported elsewhere [7].

Cement Milling

Cement Milling. Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed are difficult to grind. Rapid ...
