Our Products

  • 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.

  • Impact Crusher

    An impact crusher is a piece of heavy construction equipment people can use to reduce the size of things like rock, waste concrete, and similar 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.

  • 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.

  • Dust Catcher

    A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas.

  • 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.
