Sep 15, 2005 . industries such as steel, ceramic, cement, glass and cosmetics manufacturers. With respect to grinding media, world wide steel consumption alone is estimated at over 600 000 tonnes per annum. As such developing the ability of predicting mill wear will allow a more accurate estimate of wear cost.1) But.

and enables choice of mill configuration. In clinker, the alite (C3S) cracks more easily than belite (C2S). That means clinker with high lime saturation has a better grindability. 8 . This study considersclinker grinding in ball mill.We proposemore precise empirical equation for modified HGI relating withgrindability m, for broad.

conditions which are different from that Bond used to develop his original equation. There are efficiency factors for dry grinding, open circuit ball milling, mill diameter, oversize feed, grinding finer than 75 microns and too large or too small reduction ratios. For cement application, the dry grinding (EF1), mill diameter (EF3),.

When calculating the recommended ball top size from Bond's formula (Bond, 1961), the size for regrind applications is much lower than 25 mm. Today, the barrier for small grinding media is broken. They are best suited in regrind application. The size of grinding media is one of the most important variables affecting the mill.

Ball mills find applications in many industries like abrasives, animal products, brewing industry, chemical, confectionery, food processing, fuel preparation, metal powder, min- eral preparation, paint preparation, paper, pigments for color industry, abrasives for grinding, plastics, printing ink, rubber, textiles, sintering, cement.

Grinding media are the means used to crush or grind material (cement, mineral, …) in a mill. Grinding media sorting is performed when the ball load wears out. . He will also calculate the mill's optimum filling degree according to several parameters such as mill type and size, material to be ground, specific operating.

Apr 4, 1986 . The qualitative correlation between the calculated values of the wear components and the reported operating conditions is good for a variety of industrial ball mills, in conformity with the hypothesis that the relative magnitudes of the wear components are related to the milling conditions. .
