Lei company high pressure hanging roller mill series Model: YGM65, YGM75, YGM85, YGM95, YGM88, YGM130, YGM160 like. First, the high pressure hanging roller mill Scope: high pressure hanging roller mill grinding process is mainly applied to metallurgy, building materials, chemicals, mining and other industries material can be grinding quartz, feldspar, calcite, talcum, barite , fluorite, rare earth, marble, ceramic, bauxite, manganese ore, iron ore, copper, phosphate rock, iron oxide red, zircon sand, sand slag, cement clinker, activated carbon, dolomite, granite, pomegranate Sub stone, iron oxide yellow, bean cake, fertilizer, compound fertilizer, fly ash, bituminous coal, coking coal, lignite, Ling US sand, chromium oxide green, gold, red mud, clay, kaolin, coke, coal, clay, aquamarine stone, fluorspar, bentonite, stone, rhyolite, pyrophyllite, shale, purple rock, Diego rock, basalt, gypsum, graphite, silicon carbide, insulation materials Mohs hardness 9.3 or less, humidity is not high 6% of all kinds of non-inflammable materials. Second, the main works: Mill machine working processes (grinding material process): a large block of material by jaw crusher to the desired particle size of the material sent by the hoisting machine hopper, and then the vibration to the The material quantitative feeder evenly host grinding room continuously fed into grinding, grinding the powder was taken away after the fan air flow, the analysis of machine grading, in line with the powder fineness with the airflow through the pipe into a large cyclone collector within It was isolated and collected, and then the powder discharge pipe is finished powder. Stream again by a large cyclone collector upper return duct suction blower. The whole machine is closed loop gas flow system, and is in a state of negative pressure circulating.
