THOMPSON, CONNECTICUT USA –
Numa, the world’s leading drilling technology provider, will be exhibiting with American Sur at the 33rd PERUMIN Mining Convention taking place in Arequipa, Peru from September 18-22.
On display will be Numa hammers and bits specifically engineered for the mining industry. The mining product line boasts an impressive range of hammers and bits capable of drilling holes from 3 ½” to 20” (89 – 508 mm) in diameter. All provide the right combination of speed and life to excel against hard, abrasive, fractured and just plain nasty conditions.
Numa mining hammers have a simplified design that incorporates only eight (8) major parts. Included is a feed tube assembly that attaches directly to the backhead of the hammer to provide outstanding alignment of all hammer parts. Better alignment and less overall parts makes Numa mining hammers not only perform better but easier to maintain than competitors, which means more time drilling and reduced drilling cost.
Also on display will be Super Jaws® Overburden Bits that provide dependable performance and longevity for drilling dewatering holes through unconsolidated ground conditions of overburden, backfill or bedrock. Numa’s patented Super
Jaws produces unmatched penetration rates for simultaneously drilling and casing holes. With its unique wing design, Super Jaws retracts back into the guide body for extraction of all tooling while leaving the casing in place. There is no reverse rotation required, nor any expensive rings, saving drillers time and money in mining applications around the world.
