Product Description 1. Down the hole drilling machine, pneumatic motor driven.2. For the mine quarry, block drilling, etc3. Drilling speed: 5-8m/h4. Max depth: 30m5. TW: 250kgDown The Hole Drilling machineBQ90 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 quarryDown-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 transportation2 The high quality pneumatic components ensure lower energy & air consumpition3 The good hoisting ability4 The particular mechanical tube devices for screwing and discharging to reduce the labor intensityModelBQ90-PHole diameter (mm)φ90-100Drilling depth (M)20Specification of drill rod (mm)φ60×1150Feed travel (m)1Working pressure (Mpa)0.5~0.7Air consumption (m3/min)8~12Weight (kg)165
