#### Introduction

A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation.

Ball Mills Mine . Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Effectiveness Of A Ball Mill

Jul 13, 2016· Several of the independent variables can be reliably controlled including mill cylinder speed, media size, and of course time. Many products cannot experience elevated temperature when milling and ball mills canmodate this by jacketing the cylinder and circulating cold water. Ball mills are available from 0.1 to 5000 gal wet or dry capacity.
