Our Products

  • 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.

  • Magnetic Separator

    Wet magnetic separator is usually used for sorting the fine-grained strong magnetic minerals, or removing strong magnetic minerals from non-magnetic minerals.

  • Disk Granulator

    The disk grain making machine is suitable for the mixing ball equipment of the nutrient content is 10-30%.

  • Flotation Cell

    Flotation machine (also called flotation separator) is applicable for the separation of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc.

  • 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.

  • 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.
