The difference between vertical roller mill and ball mill The ball mill is generally composed of a horizontal cylinder, a hollow shaft for feeding and discharging, and a grinding head. The cylinder body is provided with an abrasive body, the cylinder body is made of steel plate, and the steel lining plate is fixed with the cylinder body, and the grinding body is generally a steel ball, and ...
How ball mills work. 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.
For comparison, the costs for SABC circuits grinding to 160 μm and 75 μm were determined to allow for direct comparison to HPGR-ball mill and HPGR-stirred mill circuits, respectively. The indirect cost was estimated at 45% of direct capital costs and was considered to be within industry standards for the options considered.
