Lately, we've been getting feedback from clients who are struggling to decide whether to buy a pneumatic crawler rock drill or a hydraulic crawler drilling rig?
​
CONSIDER THIS CLIENT:
"Too much oil! Gas Guzzler! This is a common complaint. Remember in the early years this kind of big crawler drilling rig began to be popular everywhere, haha, at that time the oil price is low, the salary is also high. Money is not so easy to make these years, to save fuel we have a large number of old this kind of pneumatic crawler drilling rig, are replaced by a hydraulic crawler drilling rig with an engine. I miss the benefits of the air crawler drilling rig. It's simple to build, easy to repair, cheap parts, lots of energy, low center and easy to climb."

Well, as China No. 1 supplier of a pneumatic crawler drilling rig, let's hear from the professional maintenance crew to find out what's so great about pneumatic crawler drills?

As we know, open-pit mining operations mainly include perforation, blasting, loading, transport, and discharge of soil. Blasting is an essential part of it, and it accounts for 15-20% of the total cost of open pit mining. And the quality of blasting directly affects the efficiency of equipment such as mining, transportation, and coarse crushing and the total cost of the mine. Today we would like to share some common blasting methods in open-pit mining and their application.

​​The secondary compression rotor and the secondary compression rotor are combined in a housing and driven directly by helical gears. Natural air enters the first stage through an air filter and mixes with a small amount of oil in the compression chamber while compressing the mixture to the interstage pressure. The compressed gas enters the cooling channel and comes in contact with a large amount of oil mist, thus significantly reducing the temperature. The cooled compressed gas enters the secondary rotor for a second compression, which is compressed to the final exhaust pressure. Finally, the compressor is discharged through the exhaust flange to complete the entire compression process.
