With the motor i will use a 40 mm pulley , because i have a 50 mm driven pulley, in one of my two shafts.[...]

Dec 10, 2004· The optimal ball charge filling ratio for Combiball mills is supposed to be less too. Shoji et al. (1982) investigated the influence of the ball charge filling ratio on the specific power consumption for the grinding of quartz sand. They found a flat minimum at a ball charge filling ratio of about 15%. 3.[...]

Optimization of mill performance by using online ball and pulp measurements Soon after a stop, a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples. Crash stops are difficult to handle. The mill and all feed streams should be stopped simultaneously but, often, they are stopped around about the same time.[...]
