All Grinding Mill Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.

Ball mill is a cylinder rotating at about 70-80 of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.
Chat OnlineIn SAG mill operation the grinding rate passes through a minimum at a "critical size" (Chapter 5) which represents material too large to be broken by the steel grinding media but has a low self-breakage rate. If the critical size material typically 25–50 mm is accumulated the mill energy efficiency will deteriorate and the mill feed
Chat OnlineA vibratory grinding mill will have several hundred cycles per minute of media opening and closing. The high number of impacts is combined with speed and stoke settings to produce up to 5 g s of amplification on the media. Thus General Kinematics vibratory grinding mills create a higher energy grind due to the use of their kinetic energy.
