YYG series hydraulic rock driller

YYG series full hydraulic rock drill is new high- technology products which is developed by our company and USTB( University of Science and Technology Beijing ),it has obtained many National patent. This machine composed of impact part androtation part two part, the impact and the drilling operation can be carry out in the same time. The machine used with “KD” series taphole drill machine for drill the taphole of smelting blast furnace,It has the features of big impact energy, short open time, high work Reliability and easy maintenance, can satisfy the taphole drill working needed if the smelting laster furnace less than 2000m³.

YYG500 type rock driller

YYG500 drilling machine is our company according to the current domestic large-scale blast furnace and large development trend, especially considering the large blast furnace blast furnace more than 2000m³,high smelting strength, deep iron mouth, using high strength anhydrous stemming, stemming in iron and long sintering time, the iron mouth easily bleeding iron. Iron sinter hardening uneven, balling maintenance difficulty and other factors, a new generation of high power of independent research and development of full hydraulic drilling machine, all parts of the structure of the whole machine is compact, rapid opening, using water mist duster, formed by the inner wall of the pore tight and finishing, put iron stable and more resistant to erosion, helps to reduce the clay beating resistance, it is very conducive to the taphole maintenance and mud bag forming. It has the features of big power, high efficiency, low consumption, less failure, with backhander, safety and environmental protection.
