    Vertical roller mill in cement industry,stone crushing,mineral processing

    Rock crusher: is mainly used for processing crushed rock crushing equipment. Common rock crusher including: jaw crusher, impact crusher, cone crusher and so on. Rock crusher is widely used in water and electricity, highway, artificial aggregate, crushing and other industries.

    Home Key Vertical roller mill in cement industry

    Short vertical mill vertical roller mill , a cement raw materials, cement clinker , slag and cinder grinding process used , has a simple structure and low cost of manufacture and use characteristics .

    Vertical roller mill works:Motor through reducer drive disc rotates , the material through the air lock feeder falls from the inlet central disc ,

    Stone crushing equipment,stone and ore crushing solution

    < while hot air from the inlet into the mill . As the disc rotates , the material under the centrifugal force , moving to the edge of the disc , the disc through the annular groove when subjected to roller compaction and crushing, the crushed material is at the edge of the disc with high-speed airflow from the air ring , large particles straight into the disc re- grinding , airflow through the upper part of the separator material when , under the effect of rotation of the rotor , the cone fell from coarse grinding disc again , together with the air passing the powder mill, collected by collecting device , namely the product containing materials in contact with water during the hot air is dried by adjusting the air temperature , the humidity of materials to meet different requirements, to achieve the required product water . By adjusting the separator can achieve the desired thickness of the different products .

    Wearing parts description:Vertical roller mill body and liner wear during use , due to the friction roller grinding pressure , the material reaction force , the material between the liner and the roller ; Due to grind the material into the grinding rolls caused by the shear angle mutual combined effects of stress , pressure roller mill hydraulic system and the apparent stress , such as vertical mill force , these forces are acting on the vertical mill grinding roller compacted area effectively . Once with a gap , it will impact collision between the body and liner, wear increased between the body and makes the liner, the liner makes serious cracks or fracture , causing the liner off, machine damage , especially gearhead damaged, resulting in a vicious incident .

    High quality sand washing equipment

    Once such problems occur , the general repair methods are difficult to solve , demolition , welding , machine processing fees when consuming, cut down time caused by the greatly extended , to bring irreparable huge economic losses.

    How to fix ?The use of polymer composites repair site

    Rock crusher can process a variety of particle size is not more than 120-500 mm and not more than 320 MPa compressive strength of coarse, medium and fine material ores, rocks (granite, limestone, concrete, etc.)
