Silica has found wide application not only in our daily life, but also in the high-tech field. A lot of miners show closed concern about the processing of silica or quartz. As we know, silica is a hard mineral which had Moh's hardness of 7. Therefore, machines with high running speed are not suitable for it. Ball mill has relative low speed and can be easily wear-protected, so ball mill has become the common grinding machine for silica processing. Our ball mill has the following features: 1, tailor-made according to the grindability and particle size requirement. 2, the mill is protected with Al2O3 bricks or silex to avoid iron contamination. 3, with high load of grinding media to increase grinding efficiency. 4, the input energy matches the material grindability that results in energy saving. 5, the ball mill de-dusting through an opening at the end of the mill ensures dust free. 6, robust structure and lower running speed keeps it long serving time. So we may conclude that tailor made ball mill is the most suitable equipment for silica or quartz grinding.
