HWM Series Micro Powder Ring Roller Mill

HWM series micro powder ring roller millis an ultra-fine grinding equipment with comprehensive mechanical grinding properties such as rolling, grinding, and impact. It breaks through the limitation that traditional Raymond mil can only produce less than 400mesh, and reaches the product fineness It can be flexibly adjusted between 325-2500mesh, and the final fineness can reach D 97≤3um. The grinding mil occupies a small area, is highly complete, has a wide range of uses, is simple too perate, is easy to maintain, and is cost-effective. It is an efficient and energy-saving ultra-fine grinding equipment.

Suitable for processing calcium carbonate, barite, talc, gypsum, calcite, limestone, calcium oxide, bentonite, dolomite and other non-metallic minerals with Mohs hardness below level 5 and humidity within 5%.

  • Low investment cost and high powder extraction efficiency

    At the same fineness, it has less investment, shorter cycle, 40% higher finished product fineness efficiency, and 30% lower energy consumption than ball mills, jet mills, and stirrer mills.

  • Easy to install

    There is no need for large-scale civil engineering work, the equipment can be put into use after installation, and the equipment operates smoothly and reliably.

  • Low maintenance cost and simple operation

    There are no bearings or spirals in the mill cavity, which avoids the long-term consumption of grease and burning of bearings. The wearing parts are made of high-hardness and wear-resistant materials to extend the service life.

  • Clean and environmentally friendly

    Using a complete set of negative pressure production and efficient offline dust cleaning dust collector, the dust collection efficiency is as high as 99.9%.
