LUM Ultrafine Vertical Roller Mill

LUM ultrafine vertical grinding mill is a new ultra-fine grinding equipment designed and developed by us. The ultra-fine vertical mill with ultra-fine grinding, grading and conveying has become an ideal equipment for the ultra-fine milling industry.

Product Features: Higher capacity, better powder quality, more excellent comprehensive performances
  • Input Size: 0-10mm
  • Capacity: 5-18TPH
  • Material: Limestone, calcite, dolomite, petroleum coal, gypsum, barite, marble, talc, coal powder, etc.

LUM Series Vertical Mill Ultrafine Works

LUM series vertical mill ultrafine milling process is the main motor, the disc is rotated by the main motor reducer drive, while the wind from the air inlet into LUM Ultrafine vertical mill, the material under the effect of centrifugal force by the screw feeder material to the next mouth fell to the edge of the central disc even move, after grinding roller region on the disc when subjected to rolling mill rolls, bulk materials directly crushed fine material after the material is formed by extruding intergranular bed crushed. 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 LUM ultrafine vertical roller mill grind The product. As the introduction of Germany advanced technology, multi-rotor separator, LUM absolutely no pressure to achieve ultra-fine powder.

Performance Characteristics

  • Finished product quality, high grinding efficiency.

    Device uses a vertical layer of abrasive grinding principle, the material short stay in the mill, reducing repeat milling, so that the production of high purity products, but also due to the particular mode of production and the roller sleeve lining grinding curve, so that power production equipment is relatively high.

  • Good economic returns, low investment costs.

    Device uses the principle of long separator, and each rotor frequency control are used, the fineness of grinding products can be completed within a selected range, you may not have a secondary sorting, without the presence of low-grade material, better economic ; and the device is equipped with an automatic control system, which enables remote control of such equipment operating in the production line is more simple, and the design of materials and equipment used in relatively high, the structure is strong, so that the frequency equipment damaged in the production line to reduce the number.

  • Operational safety, intelligent control system

    The main engine speed is controlled by frequency conversion, which is suitable for a wide range of materials. It is equipped with mechanical limit devices and electronic limit devices to prevent direct contact between the roller sleeve and the disc bushing to avoid damaging shock and severe vibration.

Mill Encyclopedia Knowledge

Q: The mill has no bearing rust lowest-cost approach? A: In all industrial milling equipment, mill bearing is the transmission process and the key components play a fixed load reduction in the coefficient of friction machine. Bearing rust is inevitable in the course of our problems. General mill equipment are iron and steel products, in use since the material contains water, there is moisture in the air can cause pulverizer bearing parts rust. Replaced with new bearings is a complex process, but also affect the production schedule, our mills experts can answer this question.

Mill bearing divided into the main and auxiliary bearings bearings, if the main bearings rust, can be coated with a lubricant in the bearing surface of fine sandpaper or add that, if the auxiliary bearings rust auxiliary bearings can replace what further One simple way is when the bearing rusty bearing on diesel when you can put in a little bit soaked, then fine sandpaper click on it. This approach is basically no additional cost, but also to ensure your production line is not interrupted.
