LUM Ultrafine Vertical Roller Mill
LUM ultrafine vertical roller mill is based on zenith many years experience in vertical mill developing and manufacturing, which is based on LM vertical grinding mill , Using the German ultrafine mill technology, design and development of this new type vertical roller mill . It sets grinding, drying, classifying and transportation as a whole and take little space. What's most important is that it effectively reduces the investment cost.
Vertical Roller Mill Application
LUM ultrafine vertical roller mill is widely used in calcite, marble, limestone, barite, dolomite and other non-metallic massive fine powder processing.
LUM Ultrafine Vertical Roller Mill Benefits
- LUM has excellent grinding-efficiency for the special design of roller shell and grinding plate curve.
- Low investment cost: LUM use PLC/DCS automatic control system, well save the cost of operators.
- Utilize advanced working principle and reduce the grinding time, as a result, the final products has little iron and the whiteness and purity are raised.
- LUM is of little dust and noise, achieving Environmental Protection Request, it is quite environmentally friendly
Vertical Roller Mill Working Principle
Driven by the main motor reducer rotating disc, while wind from the inlet into the LUM superfine vertical mill, the material through the screw feeder to feed port falls under the central disc, the centrifugal force, the material evenly from the center to the edge of the disc moving through the area when the grinding disc on the roller by rolling mill rolls, bulk materials directly crushed fine material formed by extrusion material bed after the inter-particle crushing.
Crushed material to the disc edge continues to move until it is taken at the air ring strong airflow, while larger particles of material to fall again on the disc to continue grinding material flow through the upper portion of the separator, the rotor under the action of the blade, coarse particles back on disc grinding, qualified powder together with the air out of grinding, is collected powder collector system, are collected into a vertical mill ultrafine powder is milled products. When mixed with the material of iron and other debris material moves to the edge of the disc, which can not be due to the large windblown own weight, falling to the mill to be installed at the bottom of the lower chamber of the disc scraper plate scraped into the slag discharge port outside the machine
