Gyratory crushers. Replacement parts identification for crushers: Allis-Chalmers® | Thyssenkrupp® | ® | ® | ® | Svedala®.

A gyratory crusher consists of a concave sur-face and a conical head; both surfaces are typically lined with manganese steel. The top of the shaft attached to the crushing cone is supported centrally in the bushings, and the bottom of the shaft is positioned in an eccentric bushing. The feed material is crushed between the

eccentric bushing in the eccentric bearing (G) via the countershaft assembly (H). This rotating eccentric bushing imparts an eccentric motion to the main shaft (B), a characteristic of the gyratory crusher. In this way the crushing gap located between the fixed concaves in the crusher shell and the eccentrically gyrating mantle continu -

CG800i crushers offer excellent reliability and safer & faster maintenance – up to 30% faster than competing crushers. A robustly designed one-piece main shaft and reinforced shells are made for tough use. The one-piece spherical spider bearing offers 5 times longer wear life than competing spider bushing design.

ECCENTRIC ASSEMBLY. The risk of burned bushings is minimal during demanding crushing operations because of large capacity reservoirs and high oil fl ow rates to eccentric and shaft bushings. All bushings are designed keyless and manufactured from leaded bronze for long life.

A primary gyratory crusher consists of a concave surface and a coni-cal head; both surfaces are typically lined with manganese steel. The top of the shaft attached to the crushing cone is supported centrally in the bushings, and the bottom of the shaft is positioned in an eccentric bushing.

The comprehensive analysis shows that the failure of the eccentric bushing is mainly due to sulfur contamination, which leads to sulfidation and oxidation under elevated temperature conditions, thus promoting corrosion and corrosion-induced cracking.

With this eccentric bushing, you have more control over your power draw, giving you better control of your crusher. Discover the improved production that one simple bushing can give. Excel bronze bushings... Simply the best! A bushing may seem like a simple part, but we have earned our reputation for superior bronze bushings because of our

Based on the analysis of working conditions and force, the failure mechanism of the eccentric bushing is studied in detail by combining macroscopic analysis, finite element analysis, scanning electron microscopy …

As the eccentric bushing rotates, the lower shaft oscillates in an elliptical orbit around the centreline of the crusher. This action causes the gap between the mantle and concave liners to open and close upon each rotation of the shaft.
