The 4170C mobile mining crusher (MMC), with a rated throughput of 10,000 to 12,000 tons per hour, is a key component in truckless mining operations. The 4170C receives mined material directly from the shovel and reduces it to a conveyable product size.
The self-propelled, integrated sizer and conveyor system features the rugged undercarriage of a P&H 4100 series shovel, severe-duty motors, and a planetary propel transmission. In addition, the mobile mining crusher is offered in model sizes that are matched to 4100-series shovels. The MMC uses electronic positioning to move in concert with the shovel to ensure correct positioning at all times. This matching allows for previously unattainable levels of operability, availability, and synchronization, leading to dramatic improvements in overall mining system availability.
Hopper
- Ground-supported during loading
- Configured to mine-specific conditions and capacity requirements
- Specific wear packages available
- Accepts run-of-mine material directly dumped by shovel
- Walls funnel to attached apron plate feeder

Centurion electrical control system
The Centurion electrical control system provides superior performance, monitoring, and data integration capabilities.
The supervisory controller, with direct integrated communication with the motor drives, allows precise motor control and fast cycle times. Real-time multi-tasking capability means optimal machine logic sequencing, monitoring, and control.
The I/O system uses the ‘Profibus’ communication protocol for seamless integration of all shovel subsystems. Low-voltage 24V DC I/O drop points feature open- and short-circuit detection for improved diagnostics and troubleshooting.
Learn how Centurion maximizes your mobile mining crusher’s efficiency.
Hydraulic breaker hammer
Breaker includes 9.1 m (30 ft.) boom and 170° swing angle to break material both on the apron feeder and in the sizer feed chute. The hammer features 6780 joules (5000 ft-pounds) of energy and a 135 mm (5.3 in.) wedge tool. The hammer operates at up to 2755 psi and 52 gpm. A 75 kW (100HP) hydraulic power unit is provided.
