LUM Series Ultrafine Vertical Roller Mill

Introduce Of LUM Series Ultrafine Vertical Roller Mill

Vertical roller mill is a kind of equipment used for raw cement, cement clinker, slag and clinker grinding processing, has the characteristics of simple structure, low cost of manufacture and use.Device and driving device includes the body, a millstone, between the body and mill plant with the centering of the rotary center determine structure, mill equipment of fixed set at the bottom of the rotary guide, slewing mill device through the rotary guide rail support on the body, the mill device connected to the gear transmission.Due to drive don't support the weight of the mill and the grinding pressure high axial load, so common decelerator gear can be used, which possesses the advantages of compact structure configuration, reliable operation, can shorten the grinding time, reduce the use of equipment and maintenance costs.

Working Principle Of LUM Series Ultrafine Vertical Roller Mill

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.

The Process Flow Of LUM Series Ultrafine Vertical Roller Mill

Vertical roller mill according to the location of humidifying tower and filter, there are two different layout, namely three fan and double fan system.Is product collection with the cyclone dust collector.This arrangement can reduce the system's working pressure and the amount of gas through the dust collector.Available electric dust collector can also use the bag dust collector in final and dust removal equipment;Can be dust collecting device or by electric dust collector bag dust collector, out of the ground gas directly into the dust collector, the system reduces the equipment sets, simplify the system configuration.

The Development Trend Of LUM Series Ultrafine Vertical Roller Mill

Vertical roller mill has a development trend in the large-scale, automation, energy efficient, easy to operate and maintain, prolong life, to expand the scope.Such as improving the mill classifier past is static, it is dynamic, changing inefficient to efficient;Outside material grinding cycle, that is, the material around the overflow when the disc is not entirely by the wind will take it to grind the top, but some of the larger particles of material through the chute, belt conveyor and elevator and other top to grind through after the election returns from the center top of the powder mill to the mill;Cement mill with a vertical roller mill.
