LUM series of ultra-fine vertical roller mill
LUM series of ultra-fine vertical roller mill is a company with years of experience in the production mill, vertical mill ordinary basis, using the latest technology in Taiwan and Germany, the roller separator technology, the new ultra-fine grinding equipment independent design and development . Set ultrafine grinding, grading, transportation in one of the ultra-fine vertical roller mill, has become the first choice for ultra-fine milling industry topics
[Feed size]: <10mm
[Capacity]: 5-18t / h
[Applications]:Widely used in chemical industry, metallurgy, non-metallic mineral industries. (More applications, please click on the "free consultation")
[Applicable materials]:Mohs hardness below 5, the density of 3.2 or less, compressive strength 150Mpa following, non-flammable mineral, non-corrosive materials brittle granular and powdered materials. Such as limestone, calcite, talc, barite, dolomite and other non-metallic minerals.
By vertical roller mill grinding abrasive layer principle, the material stays in the ground a short time, reduce duplication of milling, so few products in iron content, high whiteness and purity. Finished size of less than 2μm powder content of up to 70% to achieve a 325 mesh residue, and may increase the secondary separator elect finer particle size products.
Host speed with frequency control is widely used in a variety of materials. Grinding roller sleeve and liner specially designed curve than ordinary vertical roller mill is easier to form the material layer may be grinding to a product fineness required. The use of mechanical and electronic double limit protection device, effectively prevent the roller sleeve and disc liner in direct contact, avoid destructive impact and severe vibration.A high level of environmental protection
Vibration and low noise. Overall sealing equipment and work under negative pressure, no dust spills, clean environment, environmental requirements higher than the national standard.
Long Separator principle, and each rotor frequency control are used, the grinding fineness can be realized within the selected range, you can do the second sorting, without the presence of low-grade material. Ultrafine grinding and long separator principle, in the production of the same fineness grades, compared with other mills, saving 30% to 50%, economic good.
vertical roller mill with an automatic control system, which enables remote control, easy to operate. Using PLC / DCS automatic control of the roller pressure control, precision grinding pressure control, without manual operation. Work the roller is not in contact with the disc, and the roller and liner made of high quality materials, less wear and long life. The vertical roller mill can be dug into the outer casing repair, replacement roller sleeve, convenient liner, reducing downtime. Grinding roller lubrication lubrication station using a separate, single and dual circuit grinding roller pump - pumping while working mode, even if the roller bearings are fully lubricated and cooled, but also to avoid the roller bearing chamber oil too much memory leak occurs.
Vertical Roller Mill Works
Material falls through the screw feeder central disc, through the host drive gear motor drive disc rotating centrifugal force, so that the material is uniformly moved to lap around the area when the material through the rollers on the disc when subjected to vertical roller mill rolls , bulk material is directly crushed, squeezed smaller particles forming the bed after inter-particle crushing. After being crushed material to continue to move the edge of the disc, is from the inlet into the air with selected powder machine grading, the role of separator blade, does not meet the requirements of the powder particle falling into the grinding disc again, meet the standards by powder into the air separator pulse dust collection, the collection is finished powder powder discharged. Material mixed in iron and other impurities, because of the difficulty of grinding and gravity big edge through the disc, and can not be taken away by the air flow and fall into the inferior vertical roller mill was sent Scum scraper plate mouth, discharged outside the host.
