KSJ21 Hydraulic Mining Drilling Rig is mainly used for blast
drilling of medium length hole mining and supporting drilling
of anchor cable.Both the applicable height and width of tunnels
fall in the range height 2.9m-5.2m, width 2.8m-4.5m.
Permanent magnet variable frequency screw air compressor can maintain high motor efficiency at any speed, so the energy-saving effect is much better than that of ordinary screw air compressor.
The cooling system design is especially suitable for high temperature and high humidity environment in Asia. It has excellent vibration isolation technology and noise reduction measures.
