The Roller Mill Grinder?is mainly used for grinding mineral products in such industries as metallurgical industry, building, chemical industry, mine, etc. The YGM series Mill for Limestone Powder?can be used for grinding all kinds of nonflammable and non-explosive minerals of which Moh’s hardness and moisture content are lower than 7 and 4% respectively such as quartz, feldspar, calcite, talc, barite, fluorite, rear earth, marble, ceramics, bauxite, manganese ore, iron ore, copper ore, phosphate ore, iron oxide red, zircon sand, mineral slag, grain slag, cement clinker, activated carbon, dolomite, granite, garnet, iron oxide yellow, bean cake, chemical fertilizer, compound fertilizer, fly ash, soft coal, charred coal, lignite, magnesite, chromium oxide green, gold ore, red mud, clay, kaolin, coke, coal gangue, china clay, kyanite, fluorspar, bentonite, maifanite, rhyolite, greenstone, pyrophyllite, purple sand, shale, basalt, gypsum, graphite, carborundum, heat insulating material, etc.
? ? Roller Mill Grinder?Structure and Working Principle
? Structure A set of YGM Roller Mill Grinder?consist of main frame, decelerator, powder separator, blower, jaw crusher, bucket-elevator, vibrating feeder, hopper, bag filter, pipe-devices, motor and electric control panel, etc. ? ? Operation Principle ? When Roller Mill Grinder?works,?raw material should be crushed by the jaw crusher to the size specified, then the crushed stuff is elevated into the hopper by the bucket-elevator, through vibrating feeder, evenly and continuously into the grinding chamber for powder-processing. After this, the ground stuff is carried by the air flow from the blower into the separator for screening. The fine powder is blown into the cyclone collector and are poured out through the output-powder valves as the final product 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. ? Because the stuff contain some moisture, and the heat generated during the grinding process makes the moisture evaporated, what’s more, the pipeline joints are not airtight and therefore the external air is sucked in, all these will increase air-current in circulation and disturb the circulation balance, the balance of the air current in circulation can be realized by adjusting the pipeline of the extra air current between the blower and the grinder mainframe. After that, the powder carried by the extra air current will be collected by the dust filter. At the same time, the air current will be charged into atmosphere after purification. ?
? ? Roller Mill Grinder?Advantages and Technical Parameters ? Advantages 1. Unique design, compared to other mills with the same power, the capacity of this mill is increased by 20-30%, under the action of the high pressure spring the grinding power is enhanced by 800-1200KG.
2. It has a wide range of adjustable output size, the biggest particle size can be 0.95mm (20 mesh), while the finest size can be 0.033mm (425 mesh), a small amount of the fine product can even be 0.013mm (1000 mesh).
3. Dust cleaning can fully meet national standards.
4. Easy adjusting of the classifier.
5. Grinding roller device is of overlap multilevel seal, which has good sealing performance.
