Mill (grinding)

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 world's power (see List of countries by electricity consumption ).

APPLICATION OF HIGH FREQUENCY SCREENS IN CLOSING GRINDING CIRCUITS

Another major benefit that screen size classification offers is control over the top size of the particles that leave the grinding circuit. For example, copper flotation circuits often have poor recovery of particles coarser than 70 mesh. A screen can be used to

Grinding Circuit

An increase in grinding circuit capacity was reported due to higher breakage rates after implementing the screen. This was attributed to the elimination of the bypass, reducing the amount of fine material sent back to the grinding mills which tends to cushion particle–particle impacts.
