TYRE & ROLLER GRINDING

Rotary kilns and dryers operate under harsh extreme conditions characterised by heat, dust, chemical, mechanical stresses and long running hours during their service life.


The tough operationing conditions results in most Tyre and Trunnion Rollers wear, forming a convex, concave and conical shape including spalling, pitting and ultimately fatigue failures. The uneven wear on rollers and tyres of rotary kilns and dryers causes surface deformations that result reduced contact on surfaces and the following issues amongst others:

  1. Restricted movements or migration of kiln (up & down the kiln)

  2. Increased vibrations attributed to un-even surface contacts

  3. Increased and un-even wear on girth gear

  4. Girth gear backlash and clearance

  5. Damage to Kiln Seals



If not well managed or attended to urgently, the aforementioned factors adversely affect the alignment of the kiln and accelerate shell deformation. Conventional correction measures would result in downtime as the tyres and rollers would have to be removed, grinded and reinstalled.


With state of the art equipment and technology in its possession, Dickinson Group Pty (under its Rotary Kiln Services Unit), undertakes/offers on-site or in-situ or in-place tyre and roller grinding services to different clients across the globe. Our field technical specialist technicians are always available to attend to your technical challenges whenever required.


Objectives of Surface Grinding:

  1. Restore surface condition(s)

  2. Eliminate imperfections

  3. Normalise equipment status prior to mechanical & geometric alignment (e.g rotary kiln hot and cold alignment)

Applications:

  1. Rotary Cement Kiln tyres, support rollers and thruster rollers

  2. Rotary Dryers’ tyres, support rollers and thruster rollers

  3. Granulators

  4. Coolers

  5. Rotary Mills shafts (Ball Mill Shaft Turning and grinding)

  6. Flange facing (inside or outside diameters
