Bestlink Vertical&Horizontal DTH Rock Drill Rig for Mining

Bestlink Vertical&Horizontal DTH Rock Drill Rig for Mining 1. Down the hole drilling machine, pneumatic motor driven. 2. For the mine quarry, block drilling, etc 3. Drilling speed: 5-8m/h 4. Max depth: 30m 5. TW: 250kg 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
