Introduction
1. Size: According to the working condition of each aperture needs
2. Application: High efficiency crushing: low pressure DTH hammer through the piston reciprocating impact for high hardness of rock penetration, to adapt to the f8 above rock.
3. Environmental adaptation: Low / medium / high pressure type (more than 0.5~1.2Mpa) meet the demand of different working conditions.
4. Mobility: Caterpillar design can be fast turnarounds, suitable for site turnover more homework. By 2025, the device with compact structure, design of waste gas discharge and the strong blow function, has become the core in the field of metallurgy, coal, construction and other drilling tools.
Details
Low pressure DTH hammer is a rock drilling equipment powered by compressed gas (usually air), which is a core component of the down-the-hole drill. It drives the drill bit to break the rock through the reciprocating motion of the piston and is mainly used for hard rock drilling operations. Its characteristic lies in that the impactor works submerged in the hole, and efficient drilling is achieved by combining rotation and impact force.
