DTH hammer for tough drilling

?Our mission is to provide our customers with the finest quality equipment possible, and ensure it integrates fully with their drilling operations,? said Pejman Eghdami, executive vice president of US supplier Rockmore International. ?The release of the ROK 500 and 500Q expands the full range of our DTH hammer line from 3? to 8? diameters.?
Designed to increase drilling efficiency in quarrying, mining and blast hole applications, the ROK 500 accommodates two different air packages to match working conditions. The ROK 500 hammer is rated for use with large compressors: 24.1 bar (350 psi) at 28.6m3/min (1038 scfm). The ROK 500Q hammer is designed for smaller compressors: 24.1 bar (350 psi) at 23.4m3/min (850 scfm).
The 500 and 500Q DTH hammers take full advantage of Rockmore?s patented SonicFlow technology, which optimises airflow by simplifying and streamlining the air path to minimise backflow and turbulence, delivering more energy to the piston. Optional back reaming buttons on the top sub offer increased drill life.
The ROK 500 and 500Q have been built to withstand the toughest rock drilling conditions. The solid piston design is made from an advanced, case hardened material that combines high strength with supreme wear resistance. The high frequency, reciprocating piston is designed to strike the bit with maximum force. An innovative new design, unique to Rockmore hammers, reduces the number of hammer components, thus reducing the amount of component wear points, making hammer service simpler and less expensive.
