15/05/2014· OPEN CIRCUIT GRINDING. The mill grinds the feed to desired size in one pass and removes the product to receive the next feed. It needs more power. Needs skilled operator. Used normally for coarse grinding, when closed circuit grindinges very costly. CLOSED CIRCUIT GRINDING Mostly used in Mineral Dressing. The mill discharge is sized.
Mineral processing typically involves the crushing and grinding of hard rock ore. Crushed ore is introduced to semi autogenous grinding SAG mills, also known as primary mills, where grinding media is released like hammers to assist in the ore cracking / grinding process. The mix of media and ore rises and falls in the mill like clothes in a
