Product Description

 Description


Widely used in geotechnical engineering to wear all kinds of hard in the hard, hard and other hard to drill tough rock. The low-pressure impactor is a valve type central exhaust impactor, which has a good effect of discharging rock powder, reduces the repeated crushing of the rock slag, reduces the wear of the drill bit, improves the drilling efficiency, and adopts a new rock drilling theory to design the interior of the impactor. The size of the structure makes the impactor get the ideal energy transmission, with a single impact power, faster rock drilling, and lower air consumption. The use of high-quality raw materials and advanced processing technology results in more stable performance and longer life. Disassembly easy, low failure, easy maintenance. It is suitable for blasting holes, landslide protection, dam site reinforcement, anchorage and other engineering holes, geothermal source air conditioning, hydrology, well bore and other fields in mines, quarries and roads.
