mobilecrawlerprimary

Overview
The J-1170AS+ mobile jaw crusher combines primary crushing and onboard screening in a single tracked unit. It features a detachable onboard sizing screen, a robust Terex 1100 mm x 700 mm single-toggle jaw chamber and a hydrostatic drive enabling reversible operation. The machine can be configured for quarrying or demolition/recycling applications to provide high capacity and large reduction ratios.

Key features

• Detachable onboard screen delivering a single sized product and removing the need for a separate screening plant.
• Quick-release screening module to convert the unit into a standard crusher as required.
• Heavy-duty variable-speed VGF (vibrating grizzly feeder) for continuous full-feed to the jaw chamber.
• Hydrostatic drive with reversible function for clearing blockages and demolition work.
• Hydraulically assisted closed-side setting (CSS) adjustment for reduced downtime and rapid set-up.
