Vertical roller coal mill

Vertical roller coal mill main characteristics

  • 1, High efficiency grinding of coal, oil, lignite coke, anthracite, etc.
  • 2, Dynamic Rotary separator provides high quality final product.
  • 3, Compact design minimizes clutter.
  • 4, Sectoral castors and table wear parts extend the life of service and to facilitate installation.
  • 5, Large rollers permit coarse food for animals and to ensure a thick layer of grinding.
  • 6, Auxiliary drive not necessary.
  • 7, Flexibility ensures stable operation, even when loading low production.
  • 8, Optimized air distribution reduces pressure losses.

Vertical roller coal mill Maintenance

Uptime is the key

It is particularly important to keep execution and coal plants. Fortunately, the ATOX ™ coal plant is extremely simple to both to use and maintain.

Plan in advance

Systematic and expected maintenance is important for the vertical grinders, where measurements and Visual observations should be made during stable operation. Use your judgment of inspection testing of measures of the rollers and wear profile table.

Rollers, grinding table

Wear of the rollers and the grinding table is your greatest challenge of maintenance. It is important regularly measure the roll and wear profile table, because worn rolls or table segments lead to a loss of production and increased energy consumption.

Roller bearings

With the air tightness and lubricating roller system of roller grinding roller bearings are protected at best.Adequate replacement of fabric filter to seal air fan and the replacement of oil if necessary filter elements will result in a functioning without trouble, and long.
