High Efficiency Drill Rig 

Originated from Sandvik classic drill rig frame structure and system, with telescopic boom and oscillation, LGMRT ST120 surface top-hammer drill rig can be widely used in various mining and construction applications. When digging a hole, the drill bit revolves around the vertical axis and makes the axial movement. Soil under the torque and axial force of drill bit will  be cutting. During the process of working, under the action of centrifugal force and extrusion of the blade,  soil are destroyed and brroke up. The formation of soil flows pressure to the pit wall, at the same time along the surface up to ground. When the soil flow moves to the place, where is no barrier of pit wall, the whole excavation process is completed due to the centrifugal force of the broken earth being thrown around the pit. FEATURES High overall efficiency ——Sandvik rock drill with the advantages of low voltage, mass flow and high frequency ensures efficient drilling.…
