Our Products

  • Rotary Kiln

    A rotary kiln is a device that supplies tremendous amounts of heat in order to change the chemical composition of an object.

  • Belt Conveyor

    The convery belt is mainly composed by the expansion cylinder on both ends and the closed belts tightly knotted on them.

  • Cement Mill

    A cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.

  • 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.

  • 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.

  • Vibrating Feeder

    Vibratory feeder in the production line can transport the material with the shape of massive and particles smoothly to the feeding device in a stable time.
