10 inch DTH hammer
Model: SD10 Numa100
DTH hammer is a percussion system driving a piston inside hammer body with up and down motion by compressed air and transmitting an intensive percussion energy to the bit to enable the drilling by crushing the rocks. Drilling method by DTH Hammer exerts high drilling performance especially for drilling hard rock and contributes for shrotening work schedule. Hence, this method is widely utilized for foundation work, landslide prevention work, quarrying services, marine civil work, mining drilling, blast hole drilling, etc.
Roschen company makes and supplies the finest and most efficient down-the-hole(DTH) hammers and bits for the mining, construction and water well industries. Roschen DTH Hammers transmit intensive impact energy with low energy loss. This results in good rock breakage, high penetration rates and high productivity. Ths equipment is designed to give optimal hole quality, reliability, and long service life, as well as the best blasting results and low total operation cost.
Drill and blast engineers and water well contractors trust Roschen's DTH hammer equipment because of the precision engineering and high standards of drilling efficiency built into each of our DTH hammers and button bits.
