The use of YGM high pressure Raymond mill:
YGM high pressure Raymond mill is mainly used to grind mineral materials in metallurgy, building materials, chemical, mining and so on. It is specializing in producing fine powder of non-inflammable, non-explosive with Mohs’ hardness under seven, humidity in 6% , such as Quartz, long stone, calcite, talc, barite, fluorite, rare earth, marble, ceramic, aluminum vanadium soil, manganese mine, iron ore, copper mine, phosphorus ore, iron oxide red, zirconium British sand, slag, water slag, cement clinker, activated carbon, dolomite, granite, pomegranate zishi, iron oxide yellow, bean cake, fertilizer, compound fertilizer, fly ash, bituminous coal, coking coal, lignite, dangling beauty sand, oxidation chromium green, gold, red mud, clay, kaolin, Coke, coal gangue, China clay, blue spar , Fluorspar, bentonite, maifan rock rhyolite, pyrophyllite, purple sandstone, shale, green muddy rocks, Diego rock, basaltic stone, plaster, graphite and silicon carbide etc.
Technical features of YGM high pressure Raymond Mill:
1. High-efficiency: the full use of the jet-flow and optimized impeller structure can greatly improve the crushing and grading efficiency, thus greatly improving the production.
2. High grading degree: with the frequency conversion and grading adjustment technology, the YGM high pressure Raymond mill have stable and complete grading system and the special sealing measure , which can efficiently prevent the leaking of the fine particles .And the particle size can reach 500— 6000monyh and the thinnest can reach 12000monyh.
3. Low wearing: the crushing wearing parts and the impeller of the Raymond mill mainly adopts German technology. And with the optimized design of the inner cavity structure and anti-abrasion and allergy materials, the YGM high pressure Raymond mill has made the lowest wearing parts and the highest purity.
Working principle of YGM high pressure Raymond mill:
Firstly, raw material is crushed by jaw crusher to the size required, and then the crushed materials are elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder evenly and continuously into the grinding chamber for powder-processing. The rollers of Raymond mill oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between ring and roller to accomplish the grind. After this, the ground stuff is carried by the air from the blower into the separator for screening. The fine powers are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The airflow system is closely sealed up and circulated under condition of negative and positive pressure.
