Rockmore International introduces A Series DTH hammers
Global manufacturer of percussive rock drilling tools Rockmore International has added the ROK 600A and 650A to its ROK series DTH hammer product line.
The 600A and 650A are 6inch (152.4mm) class DTH hammers that are the first models in the newly-emerging A Class hammer range from Rockmore.
The A hammers feature new component designs that are said to demonstrate better performance and penetration rates suited to smaller compressors.
“We are committed to developing new DTH hammer solutions that increase productivity and reduce drilling operating costs,” says Pejman Eghdami, executive vice president of Rockmore International.
“Our new A Series line incorporates technological advancements that allow the hammers to be compatible with a wider range of compressors. This has been achieved by lowering air consumption rates and instilling higher efficiency levels.”
The piston and wear sleeve components have been re-designed to increase airflow efficiency at lower air volumes for the hammer, resulting in air consumption to drop to 26.5m³/minute at 24.1bar) while increasing penetration rates and further improving productivity and performance.
The new 6inch A Series hammers are targeted for DTH bits to drill from 155-178mm in mining, construction, quarry and water-well applications. Impact power is generated from a solid piston design that is made from advanced materials then case hardened.
