DTH HAMMERS.. DTH Hammers which are provided with optimum functionality and high tolerance power. These tools are extensively used for down-the-hole drilling purposes.Our series of DTH Hammers are valve less hammers with optimized air cycle frequency with high penetration rates. These are heavy duty DTH hammers that well at greater depths by less air usage; delivering minimum performance loss. Design and numerical analysis of a largediameter air In the RC-DTH air hammer drilling system, the RC drill bit is the key part to form the air reverse circulation. Most previous efforts on RC- DTH air hammer drilling focused on the performance of reverse circulation drill bits aimed at ob-taining a better design to enhance the capability of reverse circulation. Difference between DTH(Down the Hole) Drilling and Top Dec 15, 2017 · Rotation pressure (=torque) is a function of feed pressure; feed force adjustments influence the rotation resistance, recommended constant rotation pressure 90-110 bar . Flushing. Fuction is to:Remove drill cutting from the hole bottom to the surface by air blowing or water flushing. To cool a bit. Medium can be air, water, mist/foam.
