Kiln Shell Section

Replacing shell sections is a routine task for NAK employees. Experienced field personnel are the key to the correct installation of a new kiln shell section and to maintaining the repair schedule. All NAK personnel are equipped and trained in both safety and kiln service work. All crew leaders have many years of kiln experience, and are backed up by expert project managers.

Shell section replacements:

  • Riding ring pads section replacement
  • Nose section replacements
  • Shell pie cuts
  • Chain replacements
  • Nose casting replacements
  • Complete shell installations

The proper removal of the existing section is critical to allow the new section to be correctly installed. Continuing to operate a kiln with a damaged shell generally results in excessive unscheduled downtime, increased refractory costs and could lead to a catastrophic failure of the shell causing collateral damage to surrounding equipment.

Seals

Reduce your energy consumption, increase your process output, and address causes of premature failure of seals. Our overlapping seal designs address the three major factors that cause premature seal failure:

  • Radial run-out of shell
  • Axial growth or position change of shell
  • Abrasion of shell or seal components

Eliminates the effect of radial run-out of the shell or cowl by the installation of a quadrant ring and seal riding plate. The riding plate becomes the actual sealing surface.

Seal leaves are designed to accept axial movement of the riding band. Accumulations are then removed before they interfere with the pressure seals’ contact with the seal riding plate.

Support Pads

We are experts at replacing kiln tire pads and shim plates.

  • Support pads to facilitate smooth rotational movement.
  • Tire pad maintenance is essential
  • Stress on a kiln is caused primarily by improper alignment of tire pad clearances and the support rollers.

Kiln operation should employ a well-developed preventative maintenance plan, which includes items such as replacing support pads and trunnion roller base replacement. The time for the useful life of many kiln components can be extended by using high-quality kiln lubricants.

Trunnion Roller Bearings

  • Field inspections to determine any problematic causes, and turnkey field services
  • Requires periodic replacement of trunnion and mill bearings. Common causes of bearing failure, aside from normal wear over time, are high thrust loads and misalignment issues.
  • Visual inspection to confirm any problems with your bearings, and look for any particular causes of the problems. Our inspection notes will be compiled into a formal report and proposal which includes our suggested corrective actions.
  • Bearings will naturally wear with use
  • trunnion bearings can be greatly extended by using high quality bearing lubricants.
