The Center-Periphery Discharge mill has feed reporting from both ends and the product discharges ...
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter Figure 8.11. The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight.
May 27, 2016 Roller mills can typi- cally handle raw materials with an aggregate moisture of 15 while ball mills are limited to about 8. Ball mills used for drying should be air-swept using air velocity of 3-4Msec above load. Normally drying is effected by ducting part of the kiln exhaust gas through the mill.
