Spiral chute separator is the best equipment for mining and ore beneficiation. It is a kind of ideal equipment for mining sand.
In the metallurgical industry, shaker table is mineral processing equipment used for sorting fine material.
This series screen is always used in processing minerals such as ferrous metals including hematite magnet and nonferrous metals including lead, zinc, gold and silver, etc.
Wet magnetic separator is usually used for sorting the fine-grained strong magnetic minerals, or removing strong magnetic minerals from non-magnetic minerals.
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
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.
