Grinding of Calcite to Nano-Size: Effect of Mill Capacity ...

The charging rates of Cylpebs and spherical balls are given in Table 1. The material (calcite) which is grinded to the nano size is taken with the Alphine type air separator. The calcite mineral was broken to -8 mm by impact crusher before feeding to the mill. The grain size (d. 90) of the calcite feed to the mill is ~ 4 mm.

Grinding of calcite suspensions in a stirred media mill ...

2014-3-1  Concerning calcite grinding, the trend reported on the evolution of the apparent viscosity versus the mean particle size explains why it is difficult to reach fineness less than about 150 nm, even using a dispersing agent and with moderate solid concentrations. So, the suspension viscosity is a key factor to control the size reduction process in the sub-micronic range.
