Roller crusher XRS 800

stationarywet typeprimary

Overview
Primary sizers use wear-resistant pick technology derived from shearers and continuous miners. Multiple pick geometries are available to match hard, abrasive or sticky materials. Product sizing is controlled via adjustable, removable breaker bars and choice of picks.

Key features

• Wear parts designed for extended service life
• Versatile for a wide range of applications and materials
• Advanced pick technology adapted from mining equipment

High capacity
Sizers deliver high throughput, reducing the number of downstream crushers or dump stations required. They accept very large lump sizes to improve crushing ratios.

Reduced installation footprint
Sizers can be positioned where conventional crushers do not fit, making them suitable for mobile and underground installations with limited machine envelope.

Performance on wet and sticky materials
Frame-mounted cleaners scrape material accumulation. Sizers handle clay, marl and tunnel spoil effectively when processing wet or sticky feeds.

Efficient design and maintenance
Design incorporates energy-efficient helical gear reducers, robust power transmission, automatic lubrication and long-life one- and two-piece picks. Smart monitoring features support predictive maintenance.

Minimized water and dust ingress
Outboard bearing arrangement and custom seals reduce water and dust entry, enabling use of water sprays for dust suppression and material washing.

Pick options
Available pick designs address hard, abrasive and sticky applications based on experience with thousands of feeder breakers and mining machines.

Replaceable picks
Picks are replaceable on the sizer shafts, allowing renewal rather than full shaft replacement.

Product size control
Adjustable, removable breaker bars and pick selection allow control of output size and reduce transfer issues to chutes and conveyors.

Instrumentation and protection
Bearing temperature and vibration monitoring, plus locked-rotor detection and alarms, help protect the machine from tramp metal and operating anomalies.
