In the comminution industry, cone crushers are widely used for secondary and subsequent
stages of size reduction. For a given crusher, the achieved size reduction is governed by
the closed-side setting. Hadfield Steel is commonly used to line the crushing members to
minimize wear. Yet, liner wear caused by some rock types can still be excessive.
Enlargement of discharge opening induced by wear of liners produces a drift in product
size which, if unchecked, can lead to high volumes of re-circulating load. Alteration of
closed-side setting is now commonly achieved via hydraulic means. However,
compensation of liner wear still involves plant shut down and loss of production. [Continues.]
