DEFECT INSPECTIONS

A good start has positive influence on successful completion.

That is why our customers always advisable to pre seeking bids and selection of contractors, perform defects inspection, if possible in operation of the facility.

THE CAUSE OF IMPROPER OPERATION OF ROTARY KILN

HOT BEARINGS

  • The radial and axial bearings

  • Geometry of kiln axis

  • Oblique of roll axis

  • Axial “walking” of the kiln

  • Lubrication and wear of the bearing

  • The geometric shape of rolls and rings

FALL OF THE WALLING

  • Geometry of kiln axis

  • Ovality of the shell

  • Deformation of rolls and rings

  • Proper fit rolls and rings

  • Crack of the shell and roll axle

  • Inclination of the kiln

OBLIQUE OF THE ROLLS

  • Oblique of rolls

  • Improper burden

  • Touch of the ring and rolls

  • Wear of the components

  • Iregular geometry of the kiln

  • Kiln drive

THE CONE ROLLS AND RINGS

  • The cone rolls and rings

  • Shape deformation

  • The radial axial clearence

  • Inclination of the drive and kiln

  • Condition connections of tooth wreath and the kiln shell

  • Condition of axial and radial bearings

TYPES OF DEFECTS INSPECTION

DEFECT INSPECTION DETERMINED BY MEASURING OF MECHANICAL ELEMENTS

  • The radial and axial deviation of supporting rollers and rings.
  • Measurements of the diameters of the rings and roll.
  • Defining the geometric shapes (conical, concave, convex).
  • Measuring of the temperature.
  • Measurement of elements tolerances.
  • Measuring the hardness of contact surfaces.
  • Evaluation of the overall situation.
  • The conclusion of the proposed measures for rehabilitation.

DEFECT INSPECTION DETERMINED BY GEODETIC MEASUREMENTS

  • Geodetic measurements are performed in a hot condition (during operation) or cold condition (during standstill).
  • The aim (purpose) of measurements is to create conditions for the regulation (coarse and fine) to bring the object in optimal condition.
