Mr.Kerry Robinson from Australiatoday I ran the compressor and I am very happy with the workmanship and the quality , it is connected to a nitrogen generator that requires around 0.8 MPA feed air from the 30 kw compressor we are commissioning it I have found that it loads and unloads from 25.5 kw - 30 kw this will be a huge saving on power consumption.
Pedro Antonio from USAWe've been used Shanghai Rotorcomp compressors over 18 sets from 10hp to 160HP installed with Oxygen generator since 2008. Most of compressors still in good working conditions without much maintenance.

Our KG series borehole drilling rig is an updated version of our KY series hole drilling machine. The previous simple structure and reliable performance remain the same. However the hydraulic system, walking components, gyrator, driving system, pneumatic system, drill arm components, carriage components, and so on, are all optimized or updated.
As a kind of professional blasthole drilling equipment, this borehole drilling rig can be widely used for rock blasting operations in many cases like small or medium open-pit mines, water conservancy project, hydropower station building, road construction, and so on. The suitable rock hardness is in the range of F = 6-20. The diameter of the hole could be from 80mm to 165mm, while the economical drilling depth is 10-25m.
The KG920A medium pressure crawler drilling rig is an updated version of KY125 series rock hole driller. The pneumatic system, hydraulic system, drill arm components, walking parts are all optimized and upgraded. Thus the machine has stronger gradeability-the steepest slope could be in 30°. Besides, the rotating speed could be from 0r/min to 107r/min.
A detailed comparison between the KG920A and KY125 drilling machinery has been made in the form below. If you are interested in it, just contact us at any time.
Advantages of KG920A compare with KY125
|Walking parts||Motor and reducer||Ball piston motor (direct connecting)||Less pressure and longer service life for the motor|
|Drill arm||New type drill arm||Drilling horizontal and vertical holes at the same time; low height of the horizontal hole|
|Pneumatic systems||Live type impacting air valve||Ball valve||Easier control|
|Rotation speed||83r/min (diesel engine 1700r/min)
107r/min (diesel engine 2200r/min)
|55r/min||50% higher rotation speed|
|Hydraulic system||30 pumps, large new type valve group, new type flow divider, new type connector||16 pumps||Higher flow, lower resistance, and better appearance|
|Feeding speed||450mm/s||336mm/s||40% higher feeding speed|
|Rock hardness||F = 6-20|
|Economical drill depth||25m|
|Carriage rising angle||Down 135°, up 5°, total 140°|
|Carriage swing angle||Left 100°, right 45°, total 145°|
|Drill arm pitch angle||Down 50°, up 25°, total 75°|
|Drill arm swing angle||Left 44°, right 45°, total 89°|
