The Ball Mill consists of a cast iron frame with a specially designed double jacket that forces the water the circulate along a predefined path. The grinding chamber has an “8” shaped cross section providing more surface area for the transfer of cold from the double jacket than the traditional “0” shaped single shaft ball mills

Aug 30, 2008 Mechanical system of a ball mill with drive. The ball mill shell is filled up with a certain amount of the steel balls of various sizes. Together with material which is being ground they are called grinding media. By the rotation of a shell a kidney- shaped cross section of grinding media is formed at the rising side

The ventilation of a ball mill is extremely important and this for several reasons: removal of the very. fine particles, dedusting Hydraulically smooth ducts don't show uniform velocity over the whole cross-section. For this reason,. the measuring section (plane) is divided into circular rings of equal area or according the. Log.

E. A cross section of a ball mill running at speeds from 30-90% of critical speed. At 30% the grinding takes place mainly between pebbles and lining, at 70% a good cascading rolling produces efficient grinding, and at 90% very little grinding takes place. As the pebbles grind down, they contribute a small amount of material

The ball mill rotates 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. An internal cascading effect reduces the material to a fine powder. The mill can also be used for mixing,
