AN OVERVIEW OF LIME SLAKING AGT Group

2011-10-28C. BALL MILL SLAKERS Ball mill slakers are an adaptation of ball mills, which originally were designed for wet and dry grinding, to lime slaking. Two types of ball mills are used for slaking, horizontal and vertical. Ball mill slakers are generally used where the capacity required is too large for other types of slakers.

Rod mills how they function Mine EngineerCom

2012-11-26The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm 2 in. and produce a product in the size range of 3000 to 270 mm 4 to 35 mesh.

Top 5 productspecific milling technologies used in

A ball mill grinds material by rotating a cylinder filled with media typically metallic or ceramic balls mixed with a continuous flow of feed and recycled material. At slower rotational speeds, the grinding media creates a cascade motion where the media is mainly rolling and shear forces for grinding are generated.
