Differential axial shell deflection

Differential axial shell deflection – Is This A Problem With Your Kiln? by Walter Gebhart,V.P., Phillips Kiln Services   Previously published in International Cement Journal, 6/98 The serious and not uncommon problem of differential axial shell deflection is a cause for aggressive mechanical wear. Symptoms are undercut side walls of the kiln’s support tires with […]

Rotating kiln tyres: lubricating between the tyre and shell

Rotating kiln tyres: lubricating between the tyre and shell     Walter Gebhart, Phillips Kiln Services, USA discusses the philosophy of lubricating between the tyre and kiln shell.   (Reprinted from World Cement, December ) Introduction To lubricate or not to lubricate? The area under discussion is the mating surface between the bore of a […]

Using lead wire as an aid to adjusting roller skew

Using lead wire as an aid to adjusting roller skew David asks Is there any value in using lead wire to measure between the tire and roller? If so what is the procedure and results obtained.   Well, there is. First off this is a very dangerous practice. My first manager when I started this […]

Kiln Roller and Tire grooving or banding

Kiln  roller misalignment Banding     Is there any reason for circumferential marks on tire and rollers? A ridge on the kiln tire and matching grooves on both rollers as shown on the above sketch continue around the whole circumference in the middle of their widths. Would you please describe a cause for this? WeAli T. […]

Allowable Kiln Shell Flex Limits

What is the allowable degree of Kiln ovality, and how do you [get it’s] real value ?       The maximum allowable amount of shell flexing (aka ovality) is an empirically derived value based on decades of experience and studies. Maximum allowable shell flex is seen to be a function of kiln shell diameter. […]

Kiln Gear and Pinion Alignment

Kiln Gear and Pinion Alignment     Our most recent inquiry from Alan in the Asia-Pacific region: We are commisioning a 67.4m kiln with a double drive, the west side motor has the inching drive. The kiln turns clock wise from the burner end. The pinions are new but the girth gear is refurbished with […]

How does a Splined or Tangentially supported tire work?

How does a Splined or Tangentially supported tire work?     The basic design concept is to reduce ovality (the amount of shell flexing) during rotation of the kiln. Shell flexing aka ovality is typically ¼ that of a migrating tire design. The primary motive for this is that it enhances the mechanical stability of […]

Measuring Kiln Creep

“CREEP” MEASUREMENT ON MIGRATING TIRES (Refractory Lined Units)     The riding rings provide substantial strength to the shell by maintaining shell roundness. Because the shell naturally flattens out at the 12 o’clock position the riding ring system must maintain shell integrity by minimizing flex. To accommodate any difference in the expansion rate of the […]

Restoring creep to the original 6 – 12 mm: Change the shell pads!

New Filler Bar Thickness calculation based on Creep Reduction   This procedure is usually only required with refractory lined units. Non refractory lined units can still use these guidelines but make the fit tight so that the creep is as close to zero as possible. The steps in principle are outline here. The actual sequence […]
