Against the current trend of domestic mill industry and the market demand, our Exports work out Dolomite Ultrafine Grinding Machine with advanced technology. Dolomite Ultrafine Grinding Machine is a new type of ultra-fine grinding equipment. It’s mainly applied to calcite, dolomite, kaolin, bentonite, talc, barite, gypsum, alunite, and other non-flammable non-metallic materials with humidity less than 6%, Mohs hardness of eight or less. The hardness of the material determines the level of wear and length of life, when the Mohs hardness is grade 4 to 6, it will reduce the life of wear parts of Dolomite Ultrafine Grinding Machine.

Working principle of Dolomite Ultrafine Grinding Machine:
Working principle of Dolomite Ultrafine Grinding Machine is, combining mechanical crushing with gas hitting with each other to achieve the purpose of the finished product. The crushed materials go into the air classification zone, then grader sorts substandard material. The crude material not re-elected continues to return to the grinding chamber to be grinded to the required fineness. Airflow of carrying fines go into the bag collector, which separates powder from the gas stream.

Performance characteristics of Dolomite Ultrafine Grinding Machine:
Performance characteristics of Dolomite Ultrafine Grinding Machine are similar with Dolomite Raymond mill’s. But high pressure spring is set in the milling apparatus of Dolomite Ultrafine Grinding Machine, this allows the grinding pressure between the roller and grinding ring up 1.2 times. When the grinding roller and grinding ring up to a certain wear and tear, adjusting the length of high pressure spring makes grinding pressure between the ring and roller remain a constant, which is to ensure the quality and stability. Secondly, in apparatus of Dolomite Ultrafine Grinding Machine, the parts are improved with technology, which makes the contact area between the grinding roller and grinding ring reaches the maximum, so uneven small particles of material can be continuously crushed in the gap of general grinding mill.
