The larger the diameter is, the slower the rotation will be.Ball Millsare generally used to grind material ¼" and finer, down to the particle size of 20 - 75 microns. To achieve reasonable efficiency, theball millsare tobe operated in a closed system, with oversize particles continuously being re-circulated back to themilland to be reduced.
Spiral chute separator is the best equipment for mining and ore beneficiation. It is a kind of ideal equipment for mining sand.
Flotation machine (also called flotation separator) is applicable for the separation of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc.
In the metallurgical industry, shaker table is mineral processing equipment used for sorting fine material.
Chute feeder is a kind of feeding equipment which is earlier used in storage trough and it is suitable for the short-distance transport of metallic and non-metallic materials.
Stirring tank is suitable for mixing before flotation, for various metal and ores to adequately mix pharmaceutical and pulp, and it can also be used for mixing other non-metallic minerals.
Theball mill is operated in closedcircuit with a particle-size measurement device and size-controlcyclones. Thecyclonessend correct-size material on to flotation and direct oversize material back tothe ball millfor further grinding. View chapter Purchase book. Read full chapter.
