|DTH drilling rig is a rotary drilling rig, its internal structure is different from the general rock drill. Because its valve and piston reciprocating mechanism is independent, the striker or hammer, the front end of the drill is connected directly to the drill pipe butt. When the rock drill penetrates into the hole, the piston of the piston (hammer) returns to the hole at the bottom of the rock through the valve (gas valve) during the return visit. The high-speed rotating striker (hammer) hole is connected to the butt's striker by a drill pipe through a separate pivot mechanism by an electric motor outside the hole or by a pneumatic swivel. Exhaust of rock powder mixed air during rock drilling. The mixed gas is injected into the striker through the central rod discharge mechanism of the drill pipe and then through the gas into the striker cylinder at the bottom of the cell.|
In the quarry, DTH drilling rig is mainly used for drilling blasthole. In order to recommend a suitable drill for our customers, we need to know the hole diameter and hole depth. In general, drilling operations also require the use of a suitable air compressor to provide compressed air, which is critical to proper operation of the drill.
