GEOSERVEX’s rotary kiln services include troubleshooting and root cause analysis, comprehensive hot kiln alignment, in-situ grinding of tyres, support rollers and thrust rollers, installation, maintenance, repair work, technical guidance and support on all rotary kiln equipment suppliers.

HOT KILN  ALIGNMENT MAINTENANCE & INSPECTION ROGRAMMES
Our maintenance inspection programme has been designed to help clients adopt a proactive approach to rotary kiln maintenance. Direct benefits of our maintenance and inspection programmes include:

  • Compilation of a comprehensive history of wear rates for mechanical components
  • Reduced unplanned stoppages
  • Achievement of maximum plant availability thereby increasing production and reducing operating costs
  • Reduced wear rates achieved due to rotary kilns being correctly aligned on a regular basis
  • Installation & Repair
  • Efficient planning for programmed shutdowns
  • Confident budget planning for replacement of high cost items such as girth gears, pinions, tyres and trunnion rollers

   

SURVEY PROCEDURE HOT KILN ALIGNMENT
Comprehensive hot kiln alignment ensures that rotary kilns are able to achieve maximum efficiency throughout their service lives and help customers avoid unforeseen breakdowns.

Almost all problems associated with rotary kilns can be attributed to misalignment. Although the current trend is towards ‘soft’ non-contact measurements taken from areas outside the hot air envelope along the vessel, there are inherent problems associated with this technique, such as:

  • Temperature front refraction
  • Variable light conditions
  • Oblique angles
  • Unbalanced geometric networks
  • Limitations of electronics in harsh environments

TECHNOLOGY
CEMAX Engineering Malaysia represents global leading specialist GEOSERVEX from Poland in providing measurements and analyses of rotary machine deformations and measurements.

GEOSERVEX since its inception in 1983 is the world’s first developed and implemented technology of kiln alignment in dynamic conditions (during normal operation), termed “Hot Kiln Alignment” specialises in developing, implementing and realizing unusual and highly precise geodetic measurements. The method was patented and used in 42 countries around the world.

Our specialised high precision survey system is a coordinate system and a set of reference points, used to locate coordinates. The most specialized field of our activity are measurements and analyses of rotary machine deformations and measurements of ground displacements of industrial structures, constructions and equipment
