The results show that grinding time is a significant factor affecting the particle size composition. The suitable grinding concentration of Tongkeng ore and Gaofeng ore is 70% and 75%, respectively. The effect of mill filling ratio on Gaofeng ore is not obvious. The rotational rate has little effect on the grinding technical efficiency.

Gold ball mill is a high-efficiency and fine-grinding ball mill grinder, which is widely used in mining, chemical industry, building materials industry, and other fields.It is available in gold dressing plants to process refractory As-bearing gold ore. At the same time, it can also be applied to the secondary utilization of gold ore tailings.

Investigations were conducted on whether the greater performance of stirred mills over ball mills in fine grinding can be extended to coarse grinding applications. Four different laboratory ball mills and stirred mills have been tested to grind seven ore samples with feed sizes ranging from 3.35 mm to 150 μm.

The capacity of a 4-foot mill is about 15 or 20 tons of quartz ore per day through a 40-mesh screen.
