The design of a ball mill can vary significantly depending on the size of the required mill, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the "lengthto- - diameter" ratio, which frequently varies from 0.5 to 3.5.
This research paper contains the design aspects and analysis of the gear box used in the ball mill. The ball mill is used for the conversion of the raw stone material into the powder form by using steel balls inside. The ball mill is a cylindrical form of container that is driven by a toothed circular gear by couple of gears present in the gear ...
The High Energy Ball Mill Emax and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time - with only minor warming effects. These ball mills are also suitable for mechano chemistry.

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 charge for total of 23% ...
