the primarily used equipment in crushing are-jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant. crushing is a dry process whereas grinding is generally performed wet and hence is more energy
starting as small as 13 feet 4 m in diameter on 330 hp and as large as 24' 14.5 m in diameter on 3,300 hp, the 911mpe semi and fully autogenous mills tumble crushed ore without iron or steel grinding media. they are used when the crushed ore pieces are hard enough to perform all the grinding. sag mills tumble mainly ore but they use up to 15% volume of steel balls to assist grinding.
