Our Products

  • Chute Feeder

    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.

  • Agitation Tank

    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.

  • Shaking Table

    In the metallurgical industry, shaker table is mineral processing equipment used for sorting fine material.

  • Spiral Chute Separator

    Spiral chute separator is the best equipment for mining and ore beneficiation. It is a kind of ideal equipment for mining sand.

  • Classifier

    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

    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.
