The Jaw Crusher Overhaul List: Planning the Long-Lead Parts Nobody Stocks Until the Machine Stops
Six Weeks for a Coupling That Costs Less Than the Downtime A quarry in Central Asia scheduled a planned overhaul on a jaw crusher during the winter shutdown. The jaw plates were on the shelf, the cheek plates were on the shelf, and the maintenance team was ready. Then the fitters opened the driv...Read more -
Beyond the Liners: Sourcing Crusher Machine Spares That Keep a Crusher Turning
The Crusher That Was Down for a Bushing A quarry had its cone crusher down for eleven days. The mantle and bowl liner had been replaced on schedule in two days; the delay was caused by an eccentric bushing that nobody had in stock and that nobody had thought to order, because it was not on the w...Read more -
