The Very Best Bronze Bearing Technology
The Raptor Cone Crushers utilize bronze sleeve bearings for all moving load bearing or load transmission internal components. Our bronze technology is custom engineered to meet the specific application demand which include:

• Countershaft Bushings for operation over a wide range of speeds    without bearing failure.

• Thrust Bearings to support the high performance rotating eccentric.

• Head Bushing and Eccentric Bushings which absorb normal operating    loads and intermittent overloads such as tramp metal events.

• Socket Liner to provide support for the head and the dominant
   vertical loads

Structural Integrity
The critical load bearing components meet specifications that meet and typical exceed what is typically offered in a cone crusher. Our major components are cast with a high grade steel specification and our eccentric material selection provides greater certainty of a reliable surface finish even after years of service.

Mobility
Because of our unique emphasis on high throw and high pivot point crushing, the Raptor cone can be highly productive, versatile and mobile. The Raptor XL300 offers a mobile closed circuit plant and the Raptor XL400 offers the most productive and versatile cone crusher which is readily transportable on portable screen/cone plant.

Automation
Excel’s Raptor cone crushers use advanced overload sensing technology to detect crushing force overload. A simple alarm can activated. If desired our advanced automation system can take the necessary corrective action. The same advanced automation system can be used to optimize the crusher performance with feed control, setting adjustment and monitoring of critical lubrication and hydraulic parameters.

Versatility
The Raptor cone crusher offers more flexibility if production of high quality products which include ballast, road base and asphalt chips. The Raptor has built a strong following in the demanding mining industry for the most intense cone crusher applications

Security
Raptor cone crushers employ “Fail Safe” hydraulics to ensure the machines stay protected from mechanical overload should an accumulator bladder fail. The machine requires only one accumulator to operate safely and reliably. Should the accumulator fail and internal relief valve within the dual acting tramp release cylinders provides an immediate alternative protection of the Raptor cone crusher from severe and costly structural damage. Another standard safety feature is the counterclockwise rotation crushing action which prevents the machine from self tightening the setting when adjustment ring movement is excessive or if the ring gear brake fails.
