Screw Mill (): When used all by itself, a screw mill is an efficient compromise between tahona and roller mill. Some fibers are broken in the process, but not as much as the roller. Roller Mill (): This is a highly efficient continuous process used by a majority of tequilas made today. As mentioned above, more methanol is created ...

1. Introduction Mineral crushing is the main source of energy consumption in mineral processing. According to statistics, this consumption accounts for about 3550% of the total cost of the mine (Curry et al., 2014 ), or even higher. It may also account for % of the global electrical energy consumption ( NapierMunn, 2015).

The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.

In addition to the small angle assumption, Bland and Ford (1948) assume that the roll pressure equals the stress in the vertical direction and since the difference between them is a function of the cosine of very small angles, the error is not large, especially in cold rolling where roll diameters are usually much larger than the thickness of th...
