Vertical roller mill for short vertical mill, a cement raw materials, cement clinker, slag and slag grinding process used, has a simple structure, low cost of manufacture and use characteristics. Including between the body, the disc device and the transmission device, the body and the disc-centering means is provided to determine the structure of the rotational center of the bottom disc is fixedly provided with rotary guide means, through the rotary disc means rotatably supported on the rail body, the disc device and gear drive connection. Since the gear does not bear axial load weight and high pressure grinding disc, so gear reducer can be generic, which has the advantages of compact structure configuration, reliable, and can shorten the stop grinding time, reduce the use of equipment and maintenance costs. Studied the effects of the disc, the curvature of the vertical roller mill capacity, unit power consumption, in order to determine the optimal grinding curvature. Large parts of the disc holder and pressure frameworks were the main bearing static analysis and calculation of structures under dynamic loads, optimize the framework of cross-sectional dimensions determine the pressure to find the disc holder stress equally conducive to optimum shape of the casting process, and take full account of the effects of heat stress. Basic research and analysis, the development and design of efficient vertical mill for MLS3626 combined classifier. Key consideration separator area portion control and particle motion, limiting the mill appear as irregular exercise, from the surface to reduce the cycle load, improve grinding efficiency.
Vertical mill conditioning tower and filter based on location, there are two different layout scheme, namely three fan system and dual fan systems. Product was collected using a cyclone dust collector. This arrangement reduces the negative pressure system and the work by the amount of gas precipitator. Electric dust collector can also be used as a final bag filter dust removal equipment; dust collection device can be used in electrostatic precipitator or a bag filter, a mill gas directly into the dust collector, the system reduces the number of equipment units simplify the system configuration.
Vertical roller mill works: motor through reducer drive disc rotates, the material through the air lock feeder inlet falls from the 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 grinding roller compacted and crushed, pulverized material in the disc edges with high-speed airflow from the air ring, large particles straight into the disc on re-grinding, airflow through the upper part of the separator material when, under the effect of rotation of the rotor, meal bucket fell from the cone disc re-grinding, qualified powder together with a mill stream, collected by collecting device, namely 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 moisture. By adjusting the splitter, you can reach the desired thickness of the different products.
