Ore Blend Grinding at HPGR and Ball Mill. The ore blend was ground in a pilotscale HPGR (1 m diameter × m width) at a maximum feed rate of 50 t/h. The ground product was recirculated to the HPGR feeding hopper five or seven times, wherein every recirculation steps a sample was gathered for moisture and size distribution measurement.

The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill. When ground products present a much coarse or much fine particle size distribution, the separation process ...

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
