Wear zones: lining, tyres and rollers, thrust, seals and pads

High-temperature corrosion, abrasion, contact fatigue, fretting and axial loads require different materials and processes. Confirm each installed position separately.

$Refractory and burning-zone lining$

Refractory and burning-zone lining

Refractory Lining & Burning-Zone Lining

Lining protects the shell and establishes burning conditions. Inlet, transition, burning and cooling zones differ in temperature, chemical attack, coating and mechanical loads; confirm zoning, thickness, brick shapes and anchors from lining drawings.

Material selection: Select refractories for temperature, clinker minerals, alkali–sulfur–chlorine circulation, thermal shock and existing lining life; one grade cannot serve the entire kiln.

Inlet, outlet and transition protective liners

Kiln Inlet, Outlet & Transition Wear Liner

These protect metal areas at feed and discharge points, the inlet smoke chamber and kiln outlet. Confirm shape, segmentation, holes, overlaps, expansion gaps and refractory interfaces from installed drawings.

Material selection: Heat, abrasion, thermal cycles and local impacts act together. Assess heat- and wear-resistant alloys or composites against actual temperatures and failed parts.

High-temperature and special wear-resistant alloys Bimetallic wear-resistant structures

Kiln tyre running surface

Kiln Tyre / Riding Ring Running Surface

Tyres transfer kiln loads to rollers. Inspect diameter, width, section, hot ovality, axial position, contact band, surface damage and load distribution together with the mating rollers.

Material selection: Large forged or cast-and-forged parts require core toughness, contact fatigue resistance, sound surfaces and dimensional stability. Check residual dimensions and load capacity before setting on-site grinding allowances.

Support roller running surface

Supporting Roller Running Surface

Each station supports a tyre on two roller units. Check roller and shaft diameters, width, contact band, spalling, taper, axes and base elevations as a tyre–roller contact pair.

Material selection: Current OEM literature specifies forged rollers. Manufacture or repair requires base-material, forging-quality, heat-treatment, machining, NDT and replacement-shaft fit checks.

Thrust roller contact surface

Thrust Roller Contact Surface

The thrust roller contacts the tyre side face to control axial position. Confirm roller and shaft diameters, tyre face, contact position, thrust direction, hydraulic stroke and hot axial travel from the thrust-system design.

Material selection: Contact fatigue, edge loads, lubrication and axial impacts determine life. Check the roller, shaft, bearings and tyre face together.

Inlet / outlet graphite seal blocks

Kiln Inlet / Outlet Graphite Seal Blocks

Graphite blocks surround the shell; tension ropes and counterweights maintain contact while allowing axial, radial and wobbling movement. Confirm shape, quantity, gaps, tensioning and air-cooled casing from the seal drawing.

Material selection: Blocks require heat resistance, self-lubrication, wear resistance and accommodation of shell runout. Graphite grade, density, segmentation and supports cannot be selected by appearance alone.

High-temperature seal materials Seal materials and operating conditions

Tyre pads, shims and axial stops

Tyre Pad, Shim & Axial Stop

These support floating tyres, set clearances and limit axial travel. Confirm curvature, thickness, quantity, weld positions, stop gaps and thermal expansion from installed drawings and measurements.

Material selection: Pads face contact compression, fretting, thermal cycling and welding effects. Balance material, hardness and weldability with shell protection.

Quenched and tempered wear plate Composite wear-resistant structures

Support, tyre, gearing, hydraulic thrust and seal spares

Check drive and load-bearing spares as assemblies for installed interfaces, loads, materials, heat treatment, NDT, accuracy, lubrication and hot alignment.

Forged roller, shaft and base unit

Forged Supporting Roller, Axle & Base Unit

The roller and shaft form a permanently joined load-bearing unit; bearings on both sides and the base complete the station. Confirm diameters, width, bearing span, base datums, load and hot alignment before manufacture or repair.

Material selection: Check forging quality, material, heat treatment, NDT, fits, machining allowances and installation conditions separately for the roller, shaft, weld repair or replacement-shaft plan.

Alloy steels for rollers and shafts

Roller bearings, bushes and housings

Supporting Roller Bearing, Bush & Housing

Each roller unit has bearings on both sides and a base. Confirm journals, bush bores, oil gaps, bearing area, housing centre height, oil supply and cooling connections from drawings and measurements.

Material selection: Bearing alloy, steel backing, cast bond, scraping, oil film and journal surface determine reliability together. Replacement must account for the journal and lubrication system.

Bearing lining and plain-bearing materials

Splined / floating tyre assembly

Splined / Floating Kiln Tyre Assembly

The assembly includes the tyre and splined connection, or pads, shims, stops and retaining rings. Confirm section, diameter, width, holes, clearances, axial location and hot ovality from the full drawing set.

Material selection: Tyres, connectors and pads carry different loads and need separate material, heat-treatment, NDT, dimensional and welding specifications.

Alloy steels for tyres and connectors Wear plate for tyre pads

polguide® girth gear, pinion and shafts

polguide® Girth Gear, ترس صغير & Shafting

The self-aligning pinion shaft can move longitudinally; guide rings maintain flank and tip clearances. Check the gears, shafts, bearings, couplings, base and lubrication together.

Material selection: Compatibility depends on module, tooth count, pressure angle, helix hand, face width, centre distance, tooth and core properties, accuracy and contact pattern.

Alloy steels for girth gears, pinions and shafts

Special Tooling

OEM-documented on-site kiln grinding and inspection equipment

Only the polgrind® mobile grinding and measuring system explicitly documented by Polysius for kiln tyres, rollers and slip rings is shown here.

polgrind® mobile tyre and roller grinding equipment

polgrind® Mobile Kiln Tyre & Roller Grinding Tool

The OEM's mobile belt-grinding system repairs tyres, rollers and slip rings on site, correcting out-of-roundness, waviness, taper and damaged surfaces while reducing large-component removal.

Material selection: This dedicated kiln machining equipment requires mounting datums, permissible stock removal, belts, drive, guarding and travel paths matched to dimensions and damage.

Tyre–roller contact and repair requirements

Submit tyre or roller dimensions and damage details →

Tyre / roller roundness measurement and site records

Kiln Tyre / Roller Roundness Measurement & Documentation

Record diameter, roundness and surface condition before and after grinding to establish machining datums, control stock removal and document repair acceptance.

Material selection: Define measurement points, datums, limits, hot or cold conditions and report format for the specific kiln. Generic gauge readings do not replace an installed-equipment assessment.

Tyre, roller and contact-condition checks

Submit site inspection and repair scope →

Why is a similar diameter insufficient for replacing kiln parts?

Tyres, rollers, thrust parts, gears and seals depend on support count, loads, hot ovality, axial travel, centre distances and interfaces. Check nameplate, serial number, assembly and part drawings, and measurements.

Can only the tyre or roller be repaired?

First measure both parts for diameter, roundness, taper, contact band and axes. With systematic uneven loading, repairing one part may leave waviness, edge loading or axial wandering unresolved.

Can you coordinate on-site kiln inspection and finished-part delivery?

Yes. ANRANST can coordinate consultation, manufacturer sourcing, material and drawing checks, quality control, on-site inspection and finished-part delivery within the project scope.
