Ball Mill Ball Charging Mill ball charging systems have undergone little change during the past two decades most operations utilize a locomotiveball car combination to load and haul charges from the ball storage bin to the mill charging boxes or alternatively transport charges to the charging boxes by means of a ball bucket handled by bridge crane.

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball …

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

The type of mill also is a factor as if it is an overflow mill (subject to the diameter of the discharge port) is usually up to about 40-45%. If it is a grate discharge you will have more flexibility of the total charge. Ball size and ball grade is determined by the feed ore size and hardness, plus the PH level of the slurry.

The eight grate discharge mills in the older building could not be charged with two different sized balls because of storage and charging problems related to the older facility.

When charging a grinding mill, the standard practice is to dump tons of balls into the mill at once and replace them somewhere between once a shift and once a week. It's an inefficient practice that wastes energy, impacts product particle size distribution and risks breakage of mill linings and grinding media.

The present invention is directed toward a material handling, processing and milling facility which utilizes ball milling as a means for material grinding, mixing or mechanical alloying of materials. The system includes an automatic ball charging, agitating and indexing assembly, constructed and arranged to deagglomerate and directly distribute a plurality of grinding balls to the facility.
