Ball mills are generally used to grind material 14 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.
More DetailsBall mills steel ball mills lined ball mills particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800s the basic construction of a ball mill is a cylindrical container with journals at its axis.
More DetailsBall mill high speed vsi crushers mill grinding ball mill a typical type of fine grinder is the ball milla slightly inclined or horizontal rotating cylinder is partially filled with balls usually stone or metal which grind material to the necessary fineness by friction and impact with the tumbling balls.
