This gives very precise control over product size. Terex Jaques offer total support for the life of the Gyracone crushers. Our application specialist and support engineering team can optimise your process, minimise your down-time and maximise your return on investment. The J Series Gyracone crushers have some.
The crushers have two major components that require regular maintenance or replacement – the crusher mantle and crusher concave liners - shutdown of the crusher is necessary to complete this. Newcrest required a reliable tool to inform the planning, maintenance and reliability teams on crusher shutdown dates, based on mantle and concave liner.Despite monitoring crusher operation and recording the operational service of cone crusher mantles and bowl liners, conventional cone crushers are nevertheless occasionally damaged by excessive wear on the bowl liner and the mantle, to the point of exposing the underlying head or bowl to the aggregate processed by the crusher. Failure of the.
Primary Gyratory Crusher Reliability Program. The objective of the gyratory crusher reliability program is as follows Mapping the crusher mantle and concaves for trending, thickness, etc. To ensure integrity of the mainshaft and lifting eyes for the primary crushers.Gyratory Crusher Mantle. The gyratory crusher mantle is the major wear part of the gyratory crusher. The mantle which is the movable working surface is pivoted at its top within a spider bearing under the cap of the spider arm assembly while the bottom is gyrated within an eccentric bushing which is powered by the drive assembly.
