Down The Hole Drilling machine
BQ90 series drill is a new model drill, we developed it specially used for stone quarry and the drill hole can be different diameter, depth, multi-orientation and angle.
Penumatic DTH driller (down the hole drill machine) for stone quarry
Down-the-Hole Drill Machines are mainly used for perforation working during stone quarrying. Full Pneumatic Down-The-Hole Drill Machines commonly used for drilling use a pneumatic system: The energy thrust is transmitted by compressed air. In fact Down-The-Hole Drill Machines need air compressors. The pneumatic hammers penetrate the rock mass by means of a drill rod that is nothing more than a shaped steel rod. The pneumatic system is supported or sometimes substituted by the hydraulic system in which hydraulic oil instead of air is used to transmit the energy.
Advantages:
1 Light weight, easy installation and transportation
2 The high quality pneumatic components ensure lower energy & air consumpition
3 The good hoisting ability
4 The particular mechanical tube devices for screwing and discharging to reduce the labor intensity
