Energy efficient comminution circuits Mining processes require heavy capital investments and generates high operational costs which are mainly due to high energy consumptions. Of all the mining processes, grinding circuits are the most energy intensive component consuming up to 10 times more than crushing and 100 times more than blasting.

1 Over the past 15 years, mine-to-mill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.

Following grinding in the ball mill, the material is returned via the sump (8) to the secondary hydrocyclone (9) for resizing. The trash screen (10) removes wood from the old mine workings that may have found its way into the processing circuit. The slurry that remains after this process has a very fine particle size.

F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.

Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
