Jul 07, 2020 Grinding equipment for mineral processing. The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding, the smaller the particle size. Separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the grinding fineness required for flotation.
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.
The whole mill classification process is composed of mill and classifier. and the grinding sections must be determined by technical and economic comparison according to specific conditions. in practice, most mineral processing plant adopt one or two grinding classification process, and less adopt three or grinding classification process.

For successful mineral processing design it’s critical to evaluate the possibility of preconcentration or waste diversion before grinding. Mess up this step and you could be hit with avoidable downstream CAPEX and OPEX costs. At its core, preconcentration means exploiting particle differences as early as possible so that waste material isn’t unnecessarily fed to the mill and then deposited.
