### Method of grinding cement - Cementa AB

29/07/1997· The mill 3 works with rather small grinding bodies, e.g. with a mean size of 2-10 mm, and with a reasonable residence time therein of the added cement it gives rise to the desired grinding thereof to a grain size less than k 80 =25 μm, such as k 80 =15 μm, or k 80 =10 μm, e.g. between k 80 =4 μm and k 80 =8 μm and with by weight having a size less than 15-30 μm.

A Method of C alculating Autogenous/ Semi-Autogenous ...was low retention time averaging 0.85 minutes and Steane and Hinkfuss (1978), claimed the 18 ft diameter mill size was less ef cient than smaller mills. However, the author argues ﬁ the hard coarse ore was the culprit. It was surprising that the ball mill work index was averaging only 11.6 kWh/t, which is not hard. A rod mill work index ﬁ gure was not found but was thought to be in the 16 ...

Vertical Roller Mill In Cement Industry - Shanghai .Vertical Roller Mill In Cement Industry. Vertical roller mill is an important grinding mill in cement industry. Vertical roller mills have been widely accepted for combined grinding and drying of moist raw materials due to their excellent drying capacity and low energy consumption. While a number of cement plants are still using ball mills, many have installed pre-grinders like roller press to ...
