Garnet Mineral Asphalt Flour Dolomite Powder Milling Machine is Also choice for nonflammable and non-explosive minerals of which Moh's hardness is less than 9.3, moisture content is less than 6%, for example: quartz, feldspar, calcite, talcum, barite, fluorite, Rare earth, marble, ceramic, aluminous bauxite, manganese ore, iron ore, copper ore, phosphorus rock, red ferric oxide, Zircon, slag, granulating slag, cement clinker, active carbon, dolomite, granite, garnet, yellow ferric oxide, fertilizer, multiplex fertilizer, fly ash, soft coal, coking coal, lignite, magnesite, chromium oxide green, gold ore, red clay, clay, kaolin, coal tar creosote, coal slack, porcelain clay, cyanite, fluorspar, bentonite clay, medical stone, rhyolite, greenstone pyrophillite, shale, basalt, gypsum, graphite.
After the materials are put into the grinding room of Raymond Grinding Mill, the grinding roll swings outward and presses closely upon the grinding ring due to the centrifugal force in rotation of the main shaft. The shovel carries materials to the space between the grinding roll and grinding ring, and materials are ground as the grinding roll rolls. After being ground, the powder is selected by Separator via the cycle wind of the blower and the rough powder will be back to the grinding room for regrinding. The proper powder is brought into the powder collector together with airflow. The powder comes out as end products while the airflow goes back to the powder collector in cycling to make the Raymond Grinding Mill work normally. The increased airflow comes out after purification.
if your gypsum stone size is too big (>30mm )to feed into the grinding mill , we need to crush the big stone into smaller pieces, usually use jaw crusher or hammer crusher , it's depend on the hardness and size of the stone.
The whole processof raymond vertical mill works in a negative pressure environment. First, through pipes, the air from the blower enters the cyclone collector above the storage room along with powder, and then returns to the blower through return pipe. In the way, air can be recycled. There is a powder locking equipment under the cyclone in raymond vertical mill , which isolates the outside positive air pressure and the negative air pressure inside cyclone. And this ensures high productivity.
