LUM series of vertical roller mill is our company with many years of experience in the production mill to the common vertical mill as the basis, using the latest Taiwan grinding roll and Germany separator technology, independent design and development of new superfine grinding equipment.

Maintenance of vertical roller mill

Vertical roller mill is mainly composed of the main engine, the separator, the blower and so on. It plays an important role in the field of ultrafine grinding. Its working principle is to break through the jaw crusher, the material will be opened, after entering the host grinding, and finally the same separator will achieve the fineness of the material output. Therefore, the last part of the separator is an important core component, of course, there are other kinds of vulnerable parts. First of all, when the separator superfine grinding machine malfunction, should first turn off the power. Check the level and pressure of the separator is a big change. If there are changes, you should manually adjust the reset, it should also be of gas regulating valve to do certain extrusion, prevent leakage, for pressure regulation have to pay attention to the temperature of the body material properties and milling machine, the pressure is too caused serious body heat. Material fineness increased, so the repair process of the pressure adjustment should be appropriate, and for the hydraulic adjustment of the separator to make the liquid level between 1/2-1/3.

Machine maintenance is also very important, to timely replacement of wearing parts, in time to replace the lubricating oil, the equipment placed in dry and ventilated place. The machine's main components in ensuring the correct position under the premise should be reliable fastening, fixed joint surface should be tightly contacted and generally 0.04 mm feeler gauge can't go in. The moving parts no matter in load and no load conditions, should be flexible, not skewed or Caton phenomenon. Superfine mill equipment failure and all handles not jitter or move on their own, dislocation, the most important and safety measures should be complete, and in good condition. Of course, if there is any doubt you can consult the Shanghai world state machine

Products Features

  1. the structure is simple and reasonable, the self - hammer is broken, the use cost is very low;
  2. unique bearing installation and advanced spindle design, so that the machine has the characteristics of heavy load and high-speed rotation.
  3. has finely, coarse grinding function;
  4. high reliability, strict security device, ensure the equipment and personal safety;
  5. smooth operation, low noise, high efficiency and energy saving, high efficiency and high efficiency;
  6. by the material moisture content, the water content can reach 8%;
  7. wear low loss, all wearing parts are made of high quality wear resistant material, long service life. A small amount of wear parts with special hard wear-resistant material, small size, light weight, easy to replace parts.
  8. internal gas flow in the vortex chamber, dust pollution is small.
  9. the material of the impeller and the vortex in the cavity is reduced the cost of the wear parts and the maintenance work. In the production process, stone can be formed to protect the bottom, the body has no wear, durable.
  10. installation method is diverse, but mobile installation.
  11. 11 product is cubic, the bulk density is big, the iron pollution is small.
