Roschen offers a full range of reverse circulation hammers with integrated bits designed to offer a cost effective, heavy-duty sampling system for obtaining a continuous, high quality geological sample. By maximizing the energy output and minimizing air consumption, Sandvik's products can assist in providing you with excellent production rates resulting in low cost per meter drilling.
Roschen can supply High quality grade Reverse Circulation Hammers, which can instead of sandvik Reverse Circulation Hammers basis on quality grade.
Roschen manufacture a complete line of Reverse Circulation hammers and spare parts, bits, the quality can instead of Mincon and Sandvik, atlas copco. Hammers are available in a wide range of sizes and styles, to provide maximum performance and longevity on all RC drilling jobs.
Reverse Circulation hammers are designed with an inner sample tube that extends through the center and into the top of the hammer bit. The RC hammer exhausts the air between the bit splines and over the face of the bit. This forces the sample into the recovery holes in the face of the bit, through the center of the hammer and upward through the drill rod inner tubes to the surface for collection. The use of a shroud or collar is required when a RC hammer is used, to help direct the return air and cuttings up through the face of the bit.
Conventional DTH hammers can also be used in RC drilling operations, but increase the potential for sample loss and contamination. A conventional DTH hammer is used in conjunction with a cross-over sub located between the hammer and drill rod. The sample travels from the face of the bit up the outside of the hammer and into the cross-over sub.
The sub directs the sample up the center of the dual wall rods and to the surface.
