Pneumatic Rock Drilling Machine (Down The Hole drill)

1. Penumatic drill machine for quarryDown-the-Hole Drill Machines are mainly used for perforation working during stone quarrying. Full Pneumatic Down-The-Hole DrillMachines commonly used for drilling use a pneumatic system: the energy thrust is transmitted by compressed air.In fact Down-The-HoleDrill 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.ModelLQ-PE-90BLQ-PE-90BTypeFull PneumaticPneumatic & ElectricDiameter of the drilling holeΦ65-Φ90Φ65-Φ90Max depth of drill hole30-40 Meter25-30MeterDrilling speed3-6 Meter/Hour4-6 Meter/HourAir consumption9-12 M 3 /Min5-8 M 3 /MinMinimum air pressure0.6Mpa0.6MpaDrilling directionAny direction (Horizontal, Vertical, Slant)Extension distance1.2 Meters1.2 MetersAdvance devicePneumatic motor, reducer, chainPneumatic motor, reducer, chainRotation devicePneumatic motor, reducerElectric motor, reducerAdjust height of down jack220mm220mmControl panelRemote control, manual change directionNet weight550 KGS560KGS
