Low-pressure DTH hammers have gained in popularity in recent years because they are ‘gentler’ on the ring bit sets compared to high-pressure hammers. This is because low-pressure hammers operate at a lower frequency and produce less impact energy, resulting in reduced wear and tear on the ring bit sets. Being more efficient and requiring less air consumption, makes them cost-effective and environmentally friendly. Engineers should consider using low-pressure DTH hammers in their drilling operations to improve drilling performance and reduce maintenance costs.
DTH Hammers: Jinxin's DTH hammers are all simple structure, easy to assemble and disassemble, as well as reliable quality and long service life. Zhuzhou Jinxin has various hammer models suitable to drill holes from 64mm to 1000 mm (2-1/2” ~ 39-3/8”) in diameter; and come with three kind: low pressure (5 ~ 7 bars), middle pressure (7 ~ 15 bar) and high pressure (7~ 30 bars).
DTH hammers mainly be produced with shank type of DHD, QL, SF, COP, Mission, SD, BR, CIR and ACD series, Diameter ranging from 2” to 8” for mining and quarrying, and 6” to 32” for water-well drilling, oil-well drilling, foundation and so on.
