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.

  • Coal Mill

    In coal-fired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace.

  • Rotary Kiln

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

  • 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.

  • Cement Kiln

    Cement rotary kiln is the main equipment of calcining the cement clinker. The characteristics of a rotary kiln are simple structure, convenient and reliable control of the producing process.

  • Dryer Machine

    The dryer machine has been mainly used for drying materials with some humidity and granularity in the fields, such as ore dressing, building materials, metallurgy, chemical industry, etc.
