Overview

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
• Shovel can approach at 270° for loading material

Propel

• Two rugged planetary gear cases independently transmit torque to drive sprockets, producing tractive effort necessary for fast, efficient propel and positioning operations
• P&H DELTA drive low-tension sprocket drive system

Apron feeder

• Heavy-duty and able to withstand impact of dumped material
• Equipped with dual-drive variable speed control
• Can be raised with hydraulics, even when partially full, for propelling

Double-roll crusher

• Modular design with easy access for maintenance
• Wheel-mounted roll out for quick shaft/teeth replacements
• Accommodates multiple material properties, such as abrasiveness or stickiness
• Dual VFD-control reversible drives

Electro magnet

• Capable of picking up tramp steel material off the discharge conveyor belt

Technology

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.
