As is known to all, the dressing operation consists of three stages: pre-dressing, dressing and post-dressing. The preparatory work before mineral dressing generally includes crushing and screening, grinding classification, hand sorting and washing, among which grinding classification is the follow-up technology of crushing and screening and also an …
BLASTING The first stage of the crushing/grinding process in a production facility begins with blasting of the ore body, where the blasted material is composed of a very wide range of sizes. Very fine material from the zones surrounding the blast holes, to large boulders exist, which require additional breakage.
Open-circuit, stage-crushing is equally well adapted to the preparation of feed for grinding mills. For such service the reduction per stage need not be limited with a view to minimizing fines; otherwise, the design factors are much the same as for the aggregates plant.

Crushing and Grinding. Crushing is the first mechanical stage in the process of comminution in which the main objective is the liberation of the valuable minerals from the gangue. In the nature minerals are usually intergrowth with other mineral species. In order to separate them, they must be unlocked through comminution (crushing and grinding).
grinding, to single stage crushing and semi-autogenous grinding (SAG) and ball mill (SAB) circuits. This progression has, not necessarily, been accompanied by an improvement in the efficiency of power utilisation in achieving the target grind size,
Third Stage - Manufacturing Cocoa Powder 1. Corse crushing After cocoa liquor squeezes out the cocoa butter, the remaining chunk is called cocoa cake. Because of its large volume, it is first coarsely pulverized into a powder. 2. Fine crushing The second time, fine pulverization is carried out to produce more fine cocoa powder and improve the ...
