8/4/2002Batch wet grinding of 2030 mesh quartz for slurry concentrations up to 56 vol.% solid showed an increase in the specific breakage rate of the top size feed as fines built up in the mill. The degree of this acceleration effect was represented by a parameter termed the acceleration factor, which depended both on the slurry concentration and the fineness of grinding.

The breakage of domestic pyrophyllite in a ball mill was evaluated via laboratory grinding tests conducted on a 1.18 0.85 mm size fraction. The tests were performed using a 20 (D) 20 (H) cm laboratory ball mill containing 2.54-cm-diameter alumina balls at a volume filling of 30% with 70% critical speed for various grinding times.

Therefore, the grinding properties of natural zeolite were studied with the emphasis on a kinetic study in a ball mill. The experimental mill employed was laboratory sized, 200 mm diameter, 191 mm length, providing a total mill volume of 6000 cm 3, with a total mass of 5.62 kg of steel balls of 25 mm diameter with a charge of 20% of the mill volume and with a rotation speed of 76 rpm.

Dry ball mill is a grinding equipment that uses dry ball milling process to grind materials. Different from the wet ball mill, the dry ball mill does not need to add water when performing the grinding operation, only relying on the impact and crushing effect of the grinding media on the material to grind the material..
