The BDY380C 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 drilling works in different kinds of mining. The working wind pressure of this machine ranges from Printing Machinery 1.05-2.46Mpa, thus the machine can complete drilling works and casing while drilling works under low, middle and high wind pressure, providing users with a larCustomized Service for Electronics ge number of choices to meet various needs and cope with different construction 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 greatly decreasing drilling costs. Thus, the machine is highly popular among different construction units and mines.
