In a cement plant, wear follows the material from rock to powder
Limestone and additives are crushed, conveyed, ground with the raw mix, preheated and burnt to clinker, then cooled, conveyed and ground again into cement. At each stage the material changes size, temperature and abrasiveness, and so does the wear. Mapping it circuit by circuit shows where a lining upgrade pays and where steel remains enough; the general picture is on our cement and aggregates page.
Crushing and raw material transfer: impact first, then sliding
The crusher discharge and the first transfer chutes take impact from large, hard lumps, followed by sliding abrasion as material settles onto belts. These zones need impact resistance or a material bed before abrasion resistance, as set out in crusher discharge chute liners. Downstream, stacker-reclaimer and belt transfers see sliding abrasion that alumina tiles in IC TILE handle well when the impact has been taken out.
Raw mill, separator and kiln feed: fine, fast, abrasive particles
In vertical roller mills and ball mill circuits, the separator, its cones and the ducts carrying ground meal see erosion by fine particles in a gas stream. Elevators carrying raw meal wear at the boot and head, as covered in bucket elevator wear liners. Process fans after the mill erode at the impeller and casing, described in fan casing wear liners. Temperature, often elevated, sets the fixing method.
Preheater, kiln and clinker: heat decides before wear
Preheater ducts and cyclones run at temperatures where adhesives cannot be used and refractory practice applies; ceramic wear linings belong only where the steel temperature allows a suitable fixing. After the cooler, clinker is hot, coarse and very abrasive: clinker chutes, crusher outlets and pan conveyor transfers combine impact and sliding wear, as discussed in clinker chute wear. Toughened ceramic such as IC IMPACT with a weld-on fixing is the usual ceramic answer where the temperature at the steel permits.
Coal grinding, cement mill and pneumatic transport: erosion in pipes and ducts
Coal mill outlets, classifier zones and the pipes carrying pulverised fuel to the burner erode at bends and transitions. Cement mill separators and the pneumatic lines carrying cement and fly ash wear at bends, diverters and the outer radius of elbows, where alumina-lined fittings in IC PIPE are typically used. The approach for these lines is on our page on pneumatic conveying, fans and ducts.
Where to start in your plant
List the wear points that stop the plant or need the most frequent intervention, and record for each the material, temperature, mechanism and current liner history. Usually a handful of locations — clinker transfer, a separator, a few pneumatic bends, an elevator boot — account for most unplanned maintenance. Send that list with photos and drawings, and Induscoat will propose a lining per location; the transfer points are covered on our page on impact and transfer point linings, and the equivalent mining map is in mining wear protection by circuit.
