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. As the introduction of Germany advanced technology, multi-rotor separator, LUM absolutely no pressure to achieve ultra-fine powder.
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.
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.
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.
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 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.
