LM series vertical grinding mill
LM series vertical grinding mill machine is a kind of large grinding equipment, is my company with many years of production experience, integrated design and development of a set of crushing, grinding, powder selection, drying, material handling and other functions in one of the five major large grinding mill equipment, has the process is concentrated, small occupation area, less investment, high efficiency energy saving, environmental protection and many other characteristics. LM series vertical grinding mill into the mine mill, coal mill, difficult to grind three types. Grinding mill is applicable to the cement industry raw material industry; coal mill can be widely applied to pulverized coal, power, iron and steel, cement, building materials, metallurgy chemical industry preparation; difficult to grind for steel, iron slag, slag, also suitable for cement clinker and other chemical raw material etc..
Working principle of vertical grinding mill
The motor drives the disc through the speed reducer to rotate, small Raymond mill also hot air can enter from the air inlet vertical mill, A&C vertical grinding mill material from the feed opening to the central disc, due to the centrifugal force, the material is moved from the center to the edge of the grinding disc disc, the disc by an annular groove, the grinding roller compacted and crushed by, crushed material continues to move to the edge of the grinding disc, until the wind ring away, and the large granular material and fall into the disc to smash, airflow materials through the upper part of the separator, guide blades under the action of coarse material from the cone bucket fell, disc, LM vertical grinding mill fine fly along with the air out of mill dust collector, is the collection, the powder is collected is the vertical mill of a product. The process of gas in the casing material in contact to be dried, humidity dry products demand. By adjusting the separator guide blade angle (small vertical mill is not adjustable) and separator rotor speed, can achieve the required thickness of products.
LM vertical grinding mill use scope
The vertical grinding mill machine is suitable for medium and small mines, chemical industry, building materials, metallurgy, refractory materials, pharmaceutical, cement and other industries. Widely used in metallurgy, building materials, chemical industry, mining and other fields, grinding processing of mining products, suitable for processing a Mohs hardness of seven below the level of humidity below 6%, in a variety of non flammable and explosive minerals, such as gypsum, talc, calcite, limestone, marble, potassium feldspar, dolomite, barite, granite, kaolin, Peng Runtu, stone, bauxite, iron oxide red, iron ore, finished 613 microns in diameter ~440 microns (0.613 mm -0.044 mm), through the analysis of interaction of machine and fan, which can meet the use requirements of different users.
