Wiki says "A ball mill is a type of grinder used to grind materials into extremely fine powder for use in paints, pyrotechnics, and ceramics." Many instructables refer to United Nuclear Ball Mills. Their small ball mill cost between 70 and 80 dollars. For no more than 30 and in 5 minute you can build a ball mill of appreciable performance.

The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. Power drawn by ball, semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure Ad this can be used to establish the essential features of a model for mill ...
Larger ball and SAG mills, with higher installed power ratings relative to the mill diameter, offer higher efficiency and throughput, roundtheclock reliability and the opportunity to mine in remote areas. This makes low ore grades economical to grind. ABB has delivered some of the world''s largest GMDs: • 22 MW GMD for 28'' ball mill

Three types of tests are available for mill power determinations. In most cases one of two bench scale tests is adequate. First, a Jar Mill grindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hphr/t) to grind from the design feed size to the required product size.
the mill. Ball Charge Program Abrasion In this section, ball abrasion was calculated via manufacture`s ball charge program. At the time of this research, mill ball charged, feed rate, and average moisture were 7 tons (ball size was 100 mm) per week, 720 t/h and 5%, respectively. Then, ball abrasion rate was
Ball Milling Step Over In many milling operations, the cutting tool must step over and make several adjacent cuts to complete machining a feature. As a result, a small cusp of material, called a scallop, will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill .
