# Critical Speed Ball Mill

Critical Speed Ball Mill. Aug 03 1999 Critical rotation speed of dry ball-mill was studied by experiments and by numerical simulation using Discrete Element Method DEM. The results carried out by both methods showed good agreement. It has been commonly accepted that the critical rotation speed is a function of a ball radius and a jar diameter.

• ### Ball Mill Explained saVRee

Critical speed is defined as the point at which the centrifugal force applied to the grinding mill charge is equal to the force of gravity. At critical speed the grinding mill charge clings to the mill inner surface and does not tumble. Most ball mills operate at approximately 75 critical speed as this is determined to be the optimum speed .

• ### Choose right speed to improve ball mill grinding

Ball mills generally work in a dropped state. There are many working speeds to achieve this working state but there must be the most favorable working speed. In order for the ball mill to perform normal grinding operations its working speed must be less than the critical speed. Ball mills generally work in a dropped state.
