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.
Chinaware ball mill is mainly used for the mixing and grinding of materials, and the fineness of the final products is even, thus saving motive power. It can be used in both dry grinding and wet grinding.
The disk grain making machine is suitable for the mixing ball equipment of the nutrient content is 10-30%.
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.
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.
