We’ve bought, sold, and rebuilt industrial gearboxes for years — we know the cement mill gearbox repair, not just gears in general. That experience shows up in a correct diagnosis the first time.
Standard rebuilds ship in 5–14 business days with 24–72-hour emergency service — while a new unit can be 16–30 weeks out. We get your line running sooner.
You see the full picture before you commit — retail, used, surplus, repair, and a cash offer. Some shops take your unit in, tear it down, and only then hand you a quote you’re effectively forced to accept. We give you the numbers first.
Your gearbox is never held hostage. If repair isn’t the smart move, we’ll tell you — and we’ll buy the unit for cash so you walk away ahead instead of paying to get a paperweight back.
Cement plants run the biggest, hardest-working gearboxes in industry: ball mill drives, kiln girth-and-pinion sets, and vertical roller mill (VRM) gearboxes from MAAG, Flender, FLSmidth, Wikov, and David Brown Santasalo. When one fails, the plant stops earning — and a new drive can be a year out. Repair, done by the right shop, is usually the only sane answer, and we route these jobs to partners with mill-drive test stands and the tooling these units demand.
Typical failures we see: WPU/WPV planetary stage pitting from lube breakdown, kiln pinion misalignment wear, mill-drive bearing failures that cascade into gear damage. Caught early — vibration trending, oil analysis — the repair is a fraction of catastrophic cost. Our compare shows the standard shop number and ours; on drives this size the difference funds the next overhaul.
Decommissioning a line or a whole plant? We buy cement plant gearboxes and drive components for cash — mill drives, kiln drives, spare gear sets sitting in the warehouse. Fifteen tons of alloy gearing is worth real money; don't let a demo contractor take it for free.
