Sino Grinding | Mineral Processing

Sino Grinding | Mineral Processing

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 dryer.
