foundation design criteria for sag mill and ball mill

Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral ... · Ball mill is a fine grinder. A horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics, small rocks and balls made from stainless steel. The ball charge of a SAG mill is about 29% to 30%.

SAG Mill Variable Speed Drive

Ring Motors vary the speed of the mill by changing the sta-tor frequency. A cycloconverter provides variable frequency for start, stop and speed variation during operation. Figure 1: Ring Motor of the 38' SAG-Mill of Rio Paracatú Mineraçao; Brazil 3 DesignSAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in ... · Basic design criteria used to develop the costs are tabulated in the next column: Semiautogenous mills must be kept loaded to prevent damage to balls and liners. Hardness varies considerably at most porphyry copper mines and, when the ore gets soft, tonnage is quickly added to keep the mill loaded.
