New jaw crusher

Terex Pegson's newest mobile jaw crusher plant, the Metrotrak HA, features the latest development in CSS (close side setting) hydraulic adjustment of the “M” Series single toggle jaw. This uses two tapered cross beams, removing the need for shims and drawback rod for adjustment (40 to 100 mm) of the 900 x 600 mm feed opening. Powered by a 131 kW Caterpillar diesel engine, with a hydraulically actuated power take off, the Metrotrak HA has a maximum output of 175 tonnes/hour, depending on setting and material feed.

The large hydraulically folding feed hopper (4 x 1.8 m) has a 3.6 m³ capacity and is constructed from reinforced Hardox wear-resistant plate. The 800 x 3800 mm vibrating grizzly feeder has a heavy-duty mechanical vibrating unit with twin cast eccentric shafts. Finger bars and under-screen allow grizzly fines to be directed to the main or optional side conveyor by fitting a blanking mat or wire meshes with a choice of apertures. Variable speed control allows smooth and continuous materials feed.

The integral product conveyor is 800 mm wide and the discharge height is 2.9 m. The heavy-duty crawler track undercarriage, fully skirted conveyor and remote control give short set-up times and allow easy manoeuvrability on site.

Dust suppression sprays are fitted as standard, while a side/dirt conveyor, radio remote control and magnetic overband separator are optional.
