The working principle of a ball mill is based on the premise of impact and attrition. The rotation of the shell lifts the grinding media and then releases it to impact the feed material. This results in smaller particles of the ore particles. On the other hand, this process continues until the size of the ore particles reaches the desired size.
IV. BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an L/D ratio of 1.5:1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground).
Ball Mill Working Principle In the case of a continuously operated ball mill, the material to be ground is fed from the left through a 60° cone, and the product is discharged through a 30° cone to the right.
Ball Mill Principles Ball mills, sometimes referred to as pebble mills or tumbling mills, are milling machines that take the form of cylindrical vessels containing balls mounted on a metallic frame that can revolve around its longitudinal axis.
