Blast furnace slag ( slag) is excluded from the blast furnace pig iron smelting in an industrial waste, due to its high physical and chemical activity and potential hydraulic, widely used as an admixture in the cement industry. Slag grinding equipment commonly use vertical slag mill, mainly by disc, roller, separator, pressing device, consisting of monitoring means, transmission, sprinkler systems, meals outside the circulatory system and other parts of the production process these members cooperate together to complete the production process.
GRMS slag vertical mill set crushing, drying, grinding, separator, transportation as one of the roller sleeve can be used upside down, with a small footprint, simple process, high grinding efficiency, low energy consumption, low noise, bake dry capacity, product fineness is easy to adjust, no dust pollution and convenient maintenance, reliable operation, solid materials are widely used in grinding cement, metallurgy, electric power, chemicals, ceramics, non-metallic mineral industries and ultrafine grinding.
CHAENG(Great Wall Machinery) produced GRMS slag vertical mill output of up to 180t / h, the system power consumption is generally less than 43kWh / t, slag powder finished surface area of up to 4500cm2 / g, can meet the annual output of 30 to 120 tons of slag powder production line project.
Yield: 30,0000 to 120,0000 y/a of nickel slag powder project
Fineness: 4500 ~ 4500cm2 / g
Customer Type: cement plant, grinding plant, steel mills
2, working principle
material falls under the central disc material feed tube, a constant rotational speed of the disc by means of the centrifugal force outward uniformly dispersed raw material, paving, to form a certain thickness of the material bed, the material at the same time by a plurality of roller on the grinding disc pressure, and pulverized. Material to keep the outer edge of the disc movement, leaving the disc material encountered and rise through the air ring into the hot gas within the mill, the mill housing into the central separator in continuous driving under the centrifugal force, in the process materials and hot gas had a full exchange of heat, moisture quickly evaporates. Separator control roll mill outlet fineness greater than a predetermined size particles are separated and fall back to the disc, to meet the requirements of the fineness of the material by selecting the extension into the finished product warehouse.
