Description of Pneumatic DTH Drilling Rig
Pneumatic DTH Drilling Rig can drill holes in rocks that are hard or medium hard (f>8). Whatever it is like drilling, it has the process of impact, rotation, rafting, and advancing rock drilling, all of which are impact rotary drilling. Like the rotary rock driller, it has an independent slewing mechanism and an impact mechanism. The impact mechanism of different submersible drilling rigs is mounted on the front end of the drill material and dives into the bottom of the hole, and continues to advance as the borehole extends.DTH drilling rig is named after the impactor dipped into the bottom of the hole.
Pneumatic DTH Drilling Rigs are not drilled like rock drills, and the energy loss increases with the lengthening of the drill rods, so that deep holes can be drilled. When used in boreholes, the downhole rig is compared with rock drills because the impactor penetrates into the borehole. Compared with work, the noise is greatly reduced; when applied to open-air drilling, the drilling speed is increased by 2-3 times compared with the steel wire rope impact rig, the mechanization procedure is high, and the auxiliary work time is small, in particular, the inclined hole can be drilled. It is beneficial to control the grade of ore, increase the stability of the slope, eliminate the roots and improve blasting quality.
DTH hammer is used for drilling holes through a wide range of rock types, the variety of which continues to extend well beyond the original conception of early blast hole drilling.
Down-the-Hole refers to where the hammer action occurs when compared to drifter hammers, which hammer on top of the drill string. The DTH hammer piston always makes direct contact with the drill bit and there is generally no loss of transmitted energy as the hammer drills deeper, as is the case with drifter (top hammer) rigs.
Drilling Supply Store offers a wide range of DTH hammers suitable for a variety of drilling operations. Our Down the Hole hammers provide the most versatile and cost effective rock drilling method.
Down-the-hole (DTH) hammer bits are used with Down-the-hole hammers for drilling holes through a wide range of rocks types. In conjunction with DTH hammers, drill hammer bits are designed with a splined drive for rotating the bit in the ground. Drill bits are available in different sizes and different styles so they can drill a wide range of hole sizes. Our variety of Down the Hole (DTH) bits is manufactured using high quality materials to provide you with a fine balance between penetration capability and bit life. We offer a comprehensive range of standard and made to order drill bits on an extensive selection of shanks with a wide variety of head designs to suit every projec
