LUM Ultrafine Vertical Roller Mill

LUM ultrafine series vertical roller mill is SBM to 26 years four generations of mill R & D and manufacturing experience-based, LM vertical roller mill is based on the introduction of the German ultra-fine grinding vertical roller mill technology, professional design and development of a new ultra-fine grinding equipment, specialized for grinding and classification of various non-metallic minerals, a large steel plant project desulfurization limestone powder milling, processing and preparation of slag powder of pulverized coal injection and the like. It combines ultra-fine grinding, grading, transportation and other functions into one, perfectly demonstrates the advantages of ultra-fine grinding technology system industry, and now the industry has become infinitely respected by the new Johnson children, is the first choice of many mill customers.

Advantages Of LUM Ultrafine Vertical Roller Mill

  • 1. Good economic returns. Long separator principle, and each rotor frequency control are used, the grinding fineness within the selected range can be achieved without the secondary sorting can, without the presence of low-grade material. Ultra-fine grinding and long separator principle, the same as in the production of fine grade of products, compared with other mills, saving 30% to 50%, and excellent economic efficiency.
  • 2. High levels. Small vibration, low noise. Equipment integral seal and operates under negative pressure, no dust spills, clean environment, environmental requirements higher than the national standard.
  • 3. Low investment cost. Equipped with an automatic control system, which enables remote control, easy to operate. Using PLC / DCS automatic control of roller pressure control mode, the grinding pressure precise control, without manual operation. Work roller is not in contact with the disc and the roller and liner made of high quality materials, less wear and long life. Roller can be dug into the outer housing repair, replace the roller sleeve, convenient linings, reducing downtime. Roller lubrication lubrication station using a separate, single and double-loop roller pump - pumping while working mode, even roller bearings receive adequate lubrication and cooling, but also to avoid the roller bearing chamber of memory appears excessive oil leakage.
  • 4. Excellent finished product quality. By vertical layer of abrasive grinding principle, the material stays in the mill a short time, reduce duplication of milling, so very 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, choose a finer particle size products.
  • 5. High grinding efficiency. Host speed frequency control, widely used in a variety of materials. Grinding roller sleeve and liner specially designed curve than conventional vertical roller mill is easier to form the material layer may be grinding to a product fineness required. Mechanical and electronic double limit protection device, effectively prevent the roller sleeve and disc liner in direct contact to avoid the destructive impact and severe vibration.

Advantages Of LUM Ultrafine Vertical Roller Mill

LUM Ultrafine vertical roller mill mainly consists of motor, reducer, roller device, disc device, pressing device, separator, body and petrol stations and other components.

Driven by the main motor reducer rotating disc, while the wind from the air inlet into the mill, the material by spiral feeder to the discharge port falls under the central disc, under the effect of centrifugal force, uniform material movement from the center to the edge of the disc, after the disc grinding roller area, by the rolling mill rolls, bulk materials directly crushed fine material after the material is formed by extrusion bed intergranular pulverization. Crushed material to the disc edge continues to move until it is taken away by the strong airflow at the air ring, while the larger particulate material falling onto the disc again to continue grinding the material in airflow through the upper part of the separator, the rotor under the action of the blade, coarse particles back on disc grinding, qualified powder with the air along with the mill is collected powder collector system, is collected powder is ultra-fine vertical roller mill grind product. When mixed into the mass of iron and other debris with the movement of the material to the edge of the disc, due to the large weight of its own which can not be blown up, drop down to the mill chamber is mounted at the bottom of the disc plate scraper scraped into the slag discharge port outside the machine .
