Get Pricea survey of australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (morrell, 1996). autogenous mills range
Get Pricewith regards to 3.5'- 4' media, typically for ball mills of this size (16'), max size of ball used should be around the 50-60mm. i feel that a 4 ball in a 16' ball mill is
Get Pricethe standard bond grindability test is carried out under specified conditions of mill volume, mill speed, feed particle size, a circulating load of 250 and a control
