DTH impactor
The down-the-hole impactor is a device that uses compressed air as power to impact the drill bit to break the rock through the reciprocating motion of the piston in the impactor. DTH impactor belongs to the working device of down-the-hole drill. According to the working pressure of the impactor, it can be divided into low wind pressure impactor (working pressure is 0.5~0.7Mpa) and medium wind pressure (0.7~1.2Mpa) and high wind pressure impactor (above 1.2Mpa). According to the air distribution mode and structural characteristics of the impactor, it can be divided into two types: valve and valve-less; according to the formation of the central through hole of the down-the-hole impactor, it is divided into ordinary down-the-hole impactor and reverse circulation down-the-hole impactor. It is widely used in large-scale open-pit mines, underground ore mining, anchoring engineering, quarrying and rock drilling, water well geothermal mining, construction engineering rock drilling and large-scale engineering construction.
