Product description
The Smart DML is a crawler-mounted, hydraulic tophead-drive rig that's suitable for a variety of multi-pass rotary and DTH drilling applications. It's designed specifically for production blasthole drilling of depths of 175 ft (53.3 m) with a 30 ft (9.1 m) pipe change or 205 ft (62.5 m) with the optional 35 ft (10.7 m) pipe change.
Feed pressure generates a pulldown of up to 60,000 lbf (267 kN), utilizing a diesel engine to drive the air compressor and hydraulic system. The powerful rotary tricone and DTH hammer drill delivers a hole diameter of 5 7/8 in to 10 5/8 in (150 mm to 270 mm) and can achieve a clean hole 32.5 ft (9.9 m) in single-pass applications or depths of up to 205 ft (62.5 m) in multi-pass applications.
