QL60 DTH Drilling Down The Hole Hammer For High Air Pressure Wear Resistance

Reverse Circulation Down The Hole Hammer High Air Pressure Wear Resistance

Down The Hole Hammer Introduction
 

The DTH Hammer, RC hammer is used to remove rock samples which are pushed through the machine with compressed air. When air is blown down the annulus (ring-shaped structure) of the rod, the pressure shift creates a reverse circulation, bringing the cuttings up the inner tube. When the cuttings reach a deflector box at the top of the rig, the matter is moved through a hose attached to the top of the cyclone.

The drill cuttings will travel around the cyclone until they fall through the bottom opening into a sample bag. These bags are marked with the location and depth of the place where the sample was collected and can be transported directly to the assay lab for analysis.

 

Down The Hole Hammer Characteristics
