Impact crushers are commonly used to crush rocks with a silica contain under 5% such as coal, limestone, and phosphate. The only reason why you would use an impact mill/crusher or a hammer mill on a highsilica rock is because it might be sticky in nature and rich in clay. Such high abrasion/high silica impact/hammer crusher operation see ...

A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grinds material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
