The BDY380 surface high-wind-pressure DTH drilling rig is a high-efficiency drilling machine independently developed by Xuanhua Bangda Down-the-hole Drill Co., Ltd. It is applicable to drilling works of blasting holes and non-blasting holes in the earthwork excavation construction of hydropower engineering and highway engineering, and is also the ideal equipment for blasting hole drilliOther Tools & Hardware ng works in different kinds of mining. The working wind pressure of this machine ranges from 1.05-2.46MpaCar Safety , thus the machine can complete drilling works and casing while drilling works under low, middle and high wind pressure, providing users with a large number of choices to meet various needs and cope with different constAbrasive & Grinding ruction conditions. The air consumption of the drilling rig is small due to its high drilling rate because only drilling tools consume compressed air, saving 1/3 of the energy and greatIndustrial Adhesive Products ly decreasing drilling costs. Thus, the machine is highly popular among different construction units and mines.
