The HGT Series Hydraulic Gyratory Crusher is an ultra-high-capacity primary size reduction system that integrates advanced mechanical, hydraulic, electrical, and automated control telemetry. Engineered with a steep-angle crushing chamber and an integral heavy-duty main shaft, it delivers highly stable, continuous coarse-crushing outputs ranging from 2015 to 8895 t/h under extreme mining and quarrying loads.
Optimized for deep pit installations, large stationary mining lines, and semi-mobile processing hubs handling hard, highly abrasive geological materials.
Processes massive run-of-mine hard rocks like granite and basalt into primary feed for mega-capacity commercial aggregate stations.
Acts as the critical primary crushing node for metallic ore processing lines, managing high-tonnage copper, gold, and iron ore extraction.
Supplies consistent coarse material reduction for large limestone, quartz sand, and cement raw material processing operations.
Integrates directly into fixed or semi-mobile steel-frame infrastructure layouts, maintaining mechanical structural integrity in remote environments.
Features a large-angle crushing chamber matched with extended crushing mantle surfaces and tuned stroke/speed variables. This mechanical arrangement ensures reliable primary outputs exceeding thousands of tons per hour.
The heavy-duty upper/lower frames house an integral forged steel main shaft with a large diameter. This design eliminates multi-piece structural separation risks during continuous high-hardness rock impacts.
Equipped with a continuous positive pressure sealing system that maintains air overpressure. This keeps fine quarry dust away from the eccentric mechanism and critical sub-frame bearings to extend oil life.
The spider bushing and seals can be fully serviced without removing the entire top-beam assembly. For total overhauls, a dedicated hydraulic spider separator tool simplifies on-site crane procedures.
A bottom-mounted heavy-duty hydraulic cylinder controls vertical shaft position. This system provides easy product sizing adjustments, monitors liner wear, and enables automatic fallback protection against tramp iron.
Integrated PLC and touchscreens monitor real-time lubrication pressure, temperature, shaft speed, and bearing metrics. The automated system flags faults early to lower routine diagnostic downtime.
The electric motor transmits torque through the horizontal countershaft. High-precision heavy-duty spiral bevel gears translate this rotational kinetic energy directly into the vertical eccentric sleeve assembly.
As the eccentric sleeve rotates, it forces the moving cone and main shaft assembly into a continuous rotational-pendulum pattern inside the heavy structural frame.
Run-of-mine materials entering the hopper are continuously crushed by high-force compression, splitting, and attrition between the moving mantle and fixed concave liners within the deep cavity.
Sized materials pass down through the opening via gravity. If uncrushable materials are encountered, the bottom hydraulic cylinder automatically drops the shaft assembly to clear the obstruction safely.
