What is rotary equipment?

Quick answer

Rotary equipment is process machinery built around a rotating shell: kilns, dryers, coolers, ball and SAG mills, incinerators, calciners and lime lump breakers. All of them share the same wear items — shell sections, riding rings, support and thrust rollers, girth gears and pinions, bearings and liners.

What counts as rotary equipment

Kilns, dryers, coolers, ball and SAG mills, incinerators, calciners and lime lump breakers. The material being processed travels through or is tumbled inside a shell that turns continuously, usually on riding rings supported by rollers and driven by a girth gear and pinion.

Which parts wear

Shell sections and liners, riding rings (tires), support and thrust rollers, rollers and shafts, girth gears and pinions, gearboxes and couplings, bearing housings and bronze bushings, plus process-specific items such as cooler grates, kiln chain, lifters and clinker hammers.

Parts and repair together

Because the same components wear on every machine type, Monmet supplies both replacement parts and repair services — including gearbox overhaul and main trunnion bearing repair — made to drawing or reverse-engineered from a worn sample.

Related questions

Yes — they rotate on trunnions or riding rings and share the same drive and wear components as kilns and dryers.

Monmet handles a wide range of tonnages in both steel and iron, matched to the equipment.
