GD best seller quarry blasting small portable borehole mining hydraulic hard rock drilling machine

Product Description

GD70 best seller quarry blasting small portable borehole gold mining drilling equipment is a convenient compact electric down-the-hole(DTH) drill, it has many advantages,such as high efficiency,flexible movement, easy operation, low initial investment, and good economic benefits and so on.

Working Principle:

GD70 electric drilling rig is the equipment that converts the electric energy and compressed air into mechanical energy to break rock. After electrify, the drilling tool is driven by the torque produced by cycloidal reducer through the intake seat. Compressed air are divided into two way after going through oil mist device and pneumatic valve: one way enters into the cavity of promoting cylinder, which produces an axial force drives the drilling tool to promote or elevate through the cylinder piston and guide rod; the other way enters into the impactor through the intake seat, so as to achieve impact drilling.

Application:

GD70 best seller quarry blasting small portable borehole gold mining drilling equipment is suitable for harsh work environment and place that traffic is not convenient. It is a wisdom choice for drilling in hard rock of small and medium-sized mine, earth and rock engineering and so on.
