The user's quarry is located in Central Africa and DRILL Pangolin is providing drilling technology to help improve its blasting efficiency.
The granite found in African quarries is of the highest quality. The quarry plans to mine about 4 million meters of rock a year.
The Rock hardness of this quarry is medium hardness f=8-10. After repeated tests, the quarry decided to adopt the technology of inclined hole with a diameter of 140mm and an angle of 30 degrees from the vertical direction, which can make the steps stable and the resistance lines uniform, reduce bulk rate and residue.
The African user is an expert in the industry and demands that the rotation toqure of DTH crawler drilling rig must reach 4200 N.m. After visiting the drilling site of QIN-PCR200-DTH pneumatic crawler drilling rig in Africa,they are satisfied to the quality & service of DRILL PANGOLIN, but QIN-PCR200-DTH crawler drilling is pneumatic type, the biggest rotation torque is 3600 N.m, unable to meet customer's requirements.
To help our African customer meet the drilling target for the year, we recommend KHITAN-910-DTH hydraulic crawler drilling rig and equipped with DRILL Pangolin 750 portable air compressor which is powered by liutechh.
KHITAN-910-DTH hydraulic crawler drilling rig's rotary motor which are powered by USA EATON, the biggest rotary toqure is up to 4200 N.m. At the same time, compared with QIN-PCR200-DTH pneumatic crawler drilling rig, it is more convenient traveling without air compressor and faster to swift the site because it is an engine-driven rig rather than an air-driven rig with air compressor.
