    Kinetics of fine wet grinding of zeolite in a steel ball

    Feb 16, 2009 It was also observed that the powder produced in the mill caked on the walls of the mill and balls coated by the fine material at 4 min of grinding time. In addition, the dry grinding changed its character when the material in the mill was finer than about 60 m, i.e. κ values began to decrease sharply, corresponding to 16 min of grinding time. At an 80% passing size of 60 m the dry specific rates of breakage fell to about half of the normal first-order grinding.
