Mobile impact crushers: equipment insight and trends

Mobile impact crushers work hard handling demanding size reduction for aggregates, recycling, and C&D operations. However, accelerating material at rapid speed via rotor against an impact plate is a harsh process that can lead to more maintenance activity than other crushing methods. This added stress on the equipment makes correct machine operation and condition monitoring vital to ensure that production is safe and predictable and that machine wear can be dealt with proactively.

The latest digital tools, used both on site and in the office, can help operators and managers better optimize the crushing workflow and understand their equipment. They flatten the learning curve for new operators, and they provide detailed, data-driven insight that can be used for operational planning. Here's how four OEMs approach mobile impact crusher control and connectivity.

Kleemann SPECTIVE and WPT Crushing

Kleemann crushers are outfitted with the SPECTIVE operating concept, which includes radio remote control, a smaller remote control for use from inside the cab of a loader, and a large touchscreen on the machine. SPECTIVE has been extended to SPECTIVE CONNECT, an app accessible on the operator's smartphone. Via the app, the operator can monitor the status of multiple machines while carrying out other tasks. Clear operational guidance and fault diagnosis help keep crushing operations on track.

Kleemann has expanded crushing connectivity into the greater John Deere Operations Center ecosystem to deliver more big-picture insight into crushing operations. Moving beyond day-to-day machine monitoring, Wirtgen Group Performance Tracker (WPT) Crushing, available for Kleemann crushers, provides real-time updates to the office along with deep insight into crushing operations. Operations managers can easily compare efficiency at different locations and respond to decreased production. To be compatible with WPT Crushing, the crusher needs to be outfitted with a belt scale with belt speed control and a weighing cell. Operators can easily calibrate these components via SPECTIVE.

With WPT Crushing, production volumes and utilization rates can be monitored at a glance, and service and maintenance can be optimized. For example, a drop in tonnage could indicate a problem, such as machine wear. Wear parts can then be replaced before the machine breaks down.

SBM CRUSH CONTROL

CRUSH CONTROL is SBM Mineral Processing's operating concept and digital platform that covers automation functions, sensor technology, remote control, and remote monitoring via web portal or app.

SBM has designed this system to ensure that crusher operation is safe and efficient, even for less experienced operators. On the machine, easy-to-understand pressure keys and an operator guidance and status display allow for quick adjustment of the crushing parameters and start/stop of operation. One operator can also control the crusher from the cab of the loader via the remote control.

Real-time machine location and data are available anywhere, and operations managers can configure information on operational data, production output, and the maintenance status of the plant. Remote access can be authorized, allowing technicians to quickly troubleshoot problems off-site.

Rubble Master RM NEXT and RM XSMART

Rubble Master's compact impact crushers come outfitted with RM NEXT, which includes operator-friendly controls and automated machine optimization.

On the machine's display screen, the set-up advisor helps the operator optimize settings. The machine can provide a suggested set-up — valuable for inexperienced operators — to maximize production and minimize wear. It also provides self-guided troubleshooting for common errors. Advanced service tools help efficiently identify issues to return the crusher to production faster.

Additionally, the performance indicator helps the operator find the right feed rate, and status lights provide clear machine status communication.

RM XSMART provides further connectivity, allowing the operator and manager to remotely monitor performance, equipment location, and maintenance via their smartphone or computer. A camera system is optional, giving the operator line-of-sight to critical material transfer points. Belt scales are also optional. Recordings and job reports can be shared directly from the app.

Keestrack Keestrack-er

Keestrack crushing plants feature an intuitive Relytec control panel that facilitates easy start-up and shutdown along with at-a-glance machine and production metrics. Keestrack-er is Keestrack's hub for real-time location information and status reports and provides remote access to the machine's software for adjustments and updates. Users can geofence the mobile crusher to automatically shut it down if it leaves the predefined area.

Data can be stored and retrieved to create reports and evaluate the machine's output over time — valuable for planning maintenance and finding operational efficiencies.
