High-power crushing and easy maintenance with the Gyratory Crusher NT

The TC Gyratory Crusher model gave Fuller Traylor Engineering a reputation throughout the worldwide mining industry as a provider of reliable, high quality equipment. After acquiring Fuller Company, FLSmidth has taken this original TC design and expanded on it to develop the NT line.

Safely accomplish more during shutdowns while increasing operational availability. The Gyratory Crusher “NT” incorporates all of the TC’s heavy-duty design features (Heavy Cast-Steel Shell Sections, Forged Main Shaft and Countershaft, Robust Gearing, Generous Lubrication, Long-Life Bronze Components) and focuses on coupling these historical characteristics with updated maintenance-friendly features. 

And because your needs are as unique as your business, FLSmidth offers custom-engineered solutions as an answer to our customers’ unique requests. That means that you can receive custom-engineered equipment, accessories and solutions, to suit whatever your specific needs are. 

Enjoy higher power motor and matching drivetrain without having to move into a larger size crusher. Numerous Hard-Rock applications that require oversized motors prompted FLSmidth to develop its Ultra-Duty line.

Improve the operational efficiency and scheduled maintenance practices of your Gyratory Crusher.

Bar Type Spider 
Requires smaller lay-down areas and less maintenance time than conventional ring spiders.

Countershaft Bearings
The preloaded self-adjusting tapered roller bearings automatically adjust to temperature fluctuations and wear, requiring minimal maintenance.

Main Shaft Assembly
The Main Shaft Assembly is designed with a threaded sleeve to remove stress risers from the forged shaft and self-tightening head nut to assure security.

Hydraulic Adjustment & Accumulator with Relief Valve
Adjusts shaft position, absorbs crushing spikes and relieves pressure during extreme tramp events to extend component life.

Gearing
Forged alloy gears and carburised pinions are engineered to prevent catastrophic tooth failure and ensure long service life. They are designed to AGMA standards with robust safety factors and high quality materials.

Bushings
All bushings are designed keyless and manufactured from leaded bronze for long life.

High Capacity Lubrication
The risk of burned bushings is minimal during demanding crushing operations because of large capacity reservoirs and high oil flow rates to Eccentric and Shaft bushings.

Crushing Chamber
Chamber geometry is optimised for each application to ensure even wear and high throughput.

Drive Protection Coupling
Torque Safety Coupling reduces shock loading of drive components during tramp events. The torque coupling makes it safer for personnel to remove tramp from the chamber since it relieves all preload in the drive system.

Automation System
All Gyratory Crushers are available with complete control and sub-control systems.
