When should the crusher liner be replaced?

It is crucial to replace crusher liners on time, as failing to do so before they wear out can lead to damage—specifically, to the bowl of the crusher and the seating surfaces of the mantle and concave liner plates. In some cases, even when high-quality, well-maintained wear parts are used, replacing the liners at the right moment can still result in the loss of about 50% of their original weight due to excessive wear. Keeping accurate records of liner wear is essential for assessing the extent of wear—and without proper monitoring, you may sometimes be forced to shut down the crusher entirely, which could significantly reduce your profits.
