Maintenance & service of Raptor® cone crushers
Our best-practice design gives you better access to the inside of the crusher. We provide features such as mainframe inspection ports, cartridge countershaft boxes and specially-designed tools to enable simpler, safer maintenance.
Structural integrity
The critical load bearing components of the Raptor cone crushers meet specifications that typically exceed what is commonly offered in a conventional cone crusher. The major components are cast of high grade steel. The eccentric material selection provides greater certainty of a reliable surface finish over a long period of service.
Security and safety
We use fail-safe hydraulics to protect the crusher from a mechanical overload in the event that an accumulator bladder fails. An internal relief valve within the tramp release cylinders provides immediate, alternate protection from severe and costly structural damage to the crusher. The crushing action rotates counterclockwise to prevent the machine from self-tightening the setting if the adjustment ring movement is excessive, the ring gear brake fails or the thread clamping fails.
Superior bronze bearing technology
Raptor cone crushers have highly tensile bronze sleeve bearings for all internal moving components that are load bearing or involved in load transmission. Our bronze technology uses a unique process to achieve uniform lead distribution, optimum concentricity and a structure free of pores. We custom-engineer our bushings to meet your specific application demands.
