Vertical roller mill using large-scale roller system to achieve large-batch material handling equipment grinding, compared with ordinary mill, its advantage lies in the operation of large-scale automation equipment. Vertical roller mill is widely used in cement raw materials, cement clinker, slag and slag grinding process, with simple structure, low manufacturing cost, easy to use and so on.
Included between the valve body, the disc and the actuator, the valve body and disc centering device is arranged to determine the rotation center of the structure, and the bottom of the guide device fixed by the disk is rotated, and the disc device rotates on the body by means of the guide rail, and the disc device is connected with the gear drive. Because there is no gear axle load and high pressure grinding disc, the gear reducer can be used universally, it has the advantages of compact structure, reliable and can shorten the stopping time, reduce the equipment use and maintenance cost.
Motor through reducer drive disc rotates, the material through the air lock feeder from the inlet falls central disc, while the 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 the roller compacted and crushed, crushed material in the disc edges with high-speed airflow from the air ring, large particles straight into the disc on re-grinding, the material flow through the upper separator when, under the effect of rotation of the rotor, meal bucket fell from the cone disc re-grinding, qualified powder together with the air out of grinding dust collection device through the collection, is 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 desired product water. By adjusting the splitter, you can reach the desired thickness of the different products.
Vertical roller mill special steel, high yield powder thermal power plant, cement production, coal selection, coal gangue, private power plant desulfurization limestone powder, a variety of non-metallic minerals hardness industry Hundreds of bulk ore powder production, special steel slag and blast furnace slag, fly ash, slag grinding equipment, special glass fiber industry quartz, pyrophyllite powder mineral quantity of high fineness The production of large-scale powder for chemical production of chemical raw materials; And the pre-powder grinding slag powder and cement clinker, also has a good development prospects.
