Vertical grinding mill depending on the model, processing capacity from 10-100 tons / hour range selectable from 20-2000 mesh fineness can be adjusted according to need, the particles with the management of raw materials into the mill size and moisture content requirements requirements are low, can bring their own drying system as needed, can open layout, construction and low cost, is the first choice for large-scale grinding machining centers.
LM vertical mills are mainly used in the grinding process of metallurgy, building materials, chemical, mining and other mineral industries, and it is suitable for grinding thermal insulation materials and other non-flammable burst materials whose Mohs hardness are below 9.3 such as compound fertilizer, fly ash, bituminous coal, coking coal, lignite, magnesite sand, chrome oxide green, gold, red mud, clay, kaolin, coke, coal gangue, quartz, feldspar, calcite, talcum, barite, rare earth, marble, ceramic, bauxite, manganese ore, iron ore, copper ore and so on.
The original slag production process: First, perform pre-processing slag. After drying silo slag from iron into the separator through the mesh through the preliminary screening. Secondly, in line with the particle size is fed mills, stirring constantly inside the old mill, grinding, grinding to a finer granularity. Then, the mill was grinding out again into the ultrafine powder efficient classifier for screening. Where large particles from coarse meal exports separator lower part of the discharge, the return conveyors transport back to the mill continue to be crushed, the ideal size of the finished powder is blown out from the outlet of the separator, give it away bag inside the collector, the gas is purified by the fan atmosphere row of people, finished are collected dust collector.
SCM8021 mill line. Zhejiang, a superfine flour Ltd., the company responsible Sunzong ultrafine mill industry in more than ten years, the supply of finished products to more than 160 manufacturers; SCM8021 ultrafine mill purchased from our company.
