Application of SCM Ultrafine Mill is a new type of high efficient laminated crushing equipment mechanism is developed, it is a typical device in the world used in nonferrous mines, pellet crushing and grinding, and the high pressure roller mill can improve the efficiency of mineral processing, crushing and grinding equipment is advanced to be recognized, and is spreading quickly. This paper introduces five major advantages of high pressure roller mill.
1, unit grinding energy consumption is low, production efficiency. Make full use of the high pressure roller mill crushing mechanism, the energy utilization rate is very high, with the conventional extrusion type ultra fine crusher and mill, crushing and grinding characteristic probability is greatly improved, the grinding energy consumption is significantly lower than the other grinding process, the product contains more to meet the requirements of final product size of the grain level ground.
2, can handle high moisture content of materials. For high pressure roller mill, it is best to contain a certain amount of moisture (less than 90%) in the rolling material, not only can form a better self formed roller fabric cushion, but also can improve the working life of the extrusion roller. Hard alloy column the nail roller surface wear not only minimal, and roll life can reach 7000~30000h.
3, increase the work product grade and recovery. In the treatment of minerals, high pressure can cause the mineral to disintegrate along the interface according to the property of the composition, and improve the degree of dissociation of minerals. In the exudation operation, the cracks and cracks in the particles and the surface of the particles cause the exudate to permeate, thus improving the grade of the product and the recovery rate of useful minerals.
4, less land occupation, save investment in civil engineering. Because of its compact structure, light weight and small size, the high pressure roller mill has less installation space and less occupation. The mutual extrusion grinding effect mainly occurs between the two rolls, the extrusion pressure mainly depends on the load on the base frame bear, so compared with the mill and other equipment, can save a lot of investment.
5, good production environment. The crushing mechanism of laminated material using, is enclosed in a confined space to the roller and the feeding device, by static fragmentation, generally does not produce material splash impact and vibration and noise, so the equipment is low, improve the working environment of the workers.
