LUM Ultrafine Vertical Roller Mill

LUM Ultrafine Vertical Roller Mill

Technical specifications: LUM ultrafine vertical roller mill is SBM to 30 years four generations of mill development manufacturing experience to rely on, to LM vertical mill based, introduce Germany ultrafine mill roll grinding technology, design and development of a new superfine grinding equipment, widely used in calcite, marble, limestone, calcium carbonate, talc, barite, dolomite, non metallic mineral ultrafine grinding process, is a large non metallic mineral powder size of the preferred equipment factories.

Application: sand field, dry mortar, power plant desulfurization, concrete mixing station, quartz sand etc.

Material:gravel, granite, basalt, quartz, iron ore, diabase, limestone, calcite, dolomite, barite, talc, gypsum, bentonite, etc.

LUM ultrafine vertical roller mill Outstanding advantages

Quality of finished products

The material layer grinding principle, material in the mill. The short residence time, repeated milling less, less iron content, high whiteness and purity of finished products; special design of the roller sleeve and a lining plate of the grinding curve, can be a grinding to the required fineness (0.045-0.02mm).

Advanced selection of powder technology

By using several rounds of powder selecting principle, all the rotor can be adjusted by changing the frequency, fineness in selected may be within the scope of the implementation; and the production of the same fineness, than ordinary mill energy saving 30% - 50%; production of many varieties reproducing high.

Safe and efficient operation

Machinery and equipment and electronic limit device, so as to avoid damage to the shock and vibration; using PLC / DCS automatic control of grinding roller pressure control mode, precise control, without the need for manual operation; independent of the roller lubrication station, both sufficient lubrication and prevent oil leakage.

Convenient and environmental protection

Grinding and not in direct contact with the disc, less wear, long service life; grinding roller can be dug out maintenance, convenient, reduce downtime losses; small vibration, low noise, good integral sealing property, no dust spillover, cleanness and environmental protection.

vertical roller mill working principle

LUM vertical roller mill mainly by grinding roller assembly, disc assembly, hydraulic station, drive arm assembly, powder selecting machine, main reducer, a motor, a machine body, a main reducer lubrication station, hydraulic station, PLC control cabinet and other components.

When working, the main motor through the speed reducer drives the grinding disc to rotate, while the hot air into the air from entering the mill body, material from the feed opening fall in the center of the disc, under the action of centrifugal force, material from the disc center to edge uniformly moving, through the upper millstone grinding roller area by grinding roller of roller compacted, bulk material directly crushed, fine materials were extruded forming bed material interparticle breakage.

Crushed materials continue to move to the edge of the grinding disc, until the wind ring the strong air flow away, and larger particles again fall to the disc to smash, flow of material through the upper part of the separator, in under the action of the rotor blade, coarse particles back to grinding wheel grinding, qualified fine powder with the air together out of the ground, by collecting the powder collecting device of the system, were collected from the powder is vertical mill of products. Mixed into the materials of impurities such as iron with the movement of the material to the edge of the disc, due to its own weight and can not be blown up by the wind, drop to the ball mill for cavity is mounted on the disc at the bottom of the scraping plate scraping into the ash discharge port machine outside.
