As a new type of superfine grinding equipment, the LUM ultrafine vertical roller mill integrates powder grinding, separation and transportation. With years’ experience in mill production, the LUM ultrafine vertical roller mill are designed by our company, basing on vertical mills, we introduce Taiwan’s grinding roller technology and Germany powder separating technology. As a professional medium and high-end processing equipment in plastic master batch, PVC, artificial stone, electric cable, non-woven fabrics and other industries，LUM Series Ultrafine Vertical Grinding Mill is mainly used for the ultrafine grinding of calcite, marble, limestone, talc, dolomite, barite, kaolin, wollastonite, gypsum, feldspar, pyrophylite and other non-metallic mineral ores.
The special pre-compaction device ensures grinding efficiency and fineness of finished products. Besides, small vibration of the mill decreases energy loss.
According to the material bed pulverization principle, the materials stay a short time in the mill to reduce the repeated grinding. . As a result, the iron content in the finished products is low and the whiteness and purity of the product are high .
The principle of multi-rotor powder classifiers is adopted, so the finished product fineness can be customized as selected range , with no low-grade material in existence.
By adopting PLC control system, major parameters like grinding pressure, rotating speed of grinding disc and speed of classifier etc. can be accurately controlled to achieve accurate cutting size and stable quality.
Thanks to the use of ultrafine pulverization and multi-rotor separation, LUM series ultrafine vertical grinding mill saves energy by 30% to 50% compared to a common type mill when producing the powder of the same fineness, which achieves better economic effects.
The control mode for pressure adjustment of grinding roller adopts PLC/DCS automatic control system, which ensures the accurate control of grinding pressure, high efficiency and stable operation.
Automatic control system enables remote control and simple operation.
Frequency-conversion speed regulation enables the mill to be used for materials of a wide range of hardness.
