Vertical Roller Mill Application

LUM ultrafine vertical roller mill is widely used in calcite, marble, limestone, barite, dolomite and other non-metallic massive fine powder processing.

 Ultrafine Vertical Roller Mill

Vertical roller mill routine maintenance

Vertical roller mill production number of devices installed in the system are more and more sophisticated equipment, so we must remember that in the course of its routine maintenance.

  1. Vertical roller mill replace the roller and disc and other wear-resistant parts of mill production lines, because both wear parts in direct contact with the ore material, so its service life is limited, while it is relatively easy to loose, so users in a timely manner inspection and maintenance; in addition, it is noted that the company in a vertical roller mill design, with a curved design, but because the material in the disc of flour are mostly in the position near the disc, so wear wear big roll is on one side, so when it badly worn, the user can be reverse-mounted to extend its service life.
  2. Hydraulics specific maintenance measures vertical roller mill is installed, to lift up and down the roller, and the normal operation of the hydraulic system is inseparable from the work of hydraulic station, so users should be strict maintenance and repair, and you can ask a professional service personnel.
  3. Vertical roller mill in the separator is used disc separator, its blade is easily worn slag friction, so users find the leaf blade to the timely replacement of worn or replace the entire separator.
  4. Vertical roller mill uses a thin oil lubrication, and lubrication of the bearings is mainly inside the machine, such as grinding chamber bearings, roller bearings and other internal users need to do is clean up after the timely discharge of impurity bearing lubrication to monitor the temperature of the lubricating oil to monitor the functioning of the bearing, it is found abnormal data, the best stop to check immediately.

Product advantages

  • It is quite environmentally friendly, LUM Vertical Roller Mill is of little dust and noise.
  • The final products has little iron and the whiteness and purity are quite high.
  • LUM has excellent grinding-efficiency for the special design of roller shell and grinding plate curve.
  • LUM use PLC/DCS automatic control system, well save the cost of operators.

Repair method

  1. When the material of low hardness, friability good roll is relatively high, even if a 30 mm ~ 50 mm of the material layer thickness, the moment of the compressed air are also possible, causing vibration. Measures: appropriate to reduce roll and increase the amount of water, increasing the volume of feed mill conditions according to.
  2. Feeding a small amount. The amount of vertical mill feed mill capacity must be adapted whenever the feed amount is less than the rated output, the material layer will gradually thinning, roller surface caused by direct contact with the disc surface vibration. Measures: an immediate increase in the volume of feed, due to lower roll, according to the material layer thickness increases, the amount of increase to master feeding, stable material layer to be about 50 mm after recovery roll.
