5R rollers mill is suitable for grinding various ore and chemical raw materials and other non-metallic raw materials, such as: iron ore, pulverized coal, blast furnace water slag, power plant desulfurizer, boiler injection coal, white ash, feldspar, quartz, Gypsum, barite, limestone, ceramics, slag, etc. Mohs hardness not greater than 9.3, humidity below 6%, non-flammable and explosive, high-fine powder milling of more than 280 materials in industries such as mining, metallurgy, chemical, building materials During processing, the particle size of the finished product is adjusted in the range of 80-425 mesh (the finest is 1000 mesh).
In the main machine of the 5R rollers mill, a high-pressure spring with a pressure of 1000-1500 kg is fastened on the roller hanger. After starting to work, the grinding roller rotates around the main shaft and rolls against the grinding ring under the action of high-pressure spring and centrifugal force. Its rolling pressure is 1.2 times higher than that of the Raymond powder machine under the same power condition, so the output is greatly improved.
