Our Products

  • Belt Conveyor

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

  • 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.

  • 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.

  • High Frequency Screen

    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.

  • 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.

  • 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.
