feed size distribution is different to a standard Bond ball mill work index test. A series of 10 samples for an Andean copper project were treated to both the SAGDesign (and Sd_bwi) test and the standard Bond ball mill work index test with 180 µm closing screens. The SAGDesign results (with the non-standard ball mill feed) are given in Table 1.

where conventional wet ball milling (in closed circuit with a classifier cyclone cluster) is used to reduce the limestone particle size to 95% passing 45 µm. The Kusile ball mill specific energy is 26.5 kWh/t. The dry vertical roller mill (VRM) is a novel grinding technology that dries, grinds and classifies ore within a single unit.
This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls. The drive system can either …
The overflow type ball mill is a cylindrical device with a rotating drum, typically used for grinding various ores and other materials in wet conditions. This type of ball mill operates with a continuous overflow …
In a ball mill or pebble mill the size-reduction is carried out by impact as the balls or pebbles drop from near the top of the shell. In a large ball mill the diameter of shell may be 3 m and 4.25m in length. The balls are 15 to 125 mm in diameter; the pebbles in a pebble mill are 50 to 175 mm in size.
