Blast hole drilling

From the mining of minerals, limestone to metal minerals, blast hole drilling construction is mostly used in harsh and remote areas. Such harsh working environments require robust and stable equipment to perform tasks.

AIRERA diesel portable air compressor is equipped with a low-temperature and high-altitude start-up package, stronger compressor frame and dust & water-proof equipment, anti-corrosion painting and the large-capacity diesel tank can meet the needs of uninterrupted long-term operation.

Application: Suitable for various types of mineral mining, heat& geothermal drilling projects. Drilling in mines to mine small boulders, and then obtain valuable minerals or process them into smaller particles or powders to make cement, etc., which are widely used in iron mine, copper mine, gold mine, or cement factory.

Product design features:

  • 1. Two-stage helical rotor patent, the rotor linearity is 5:6, and the energy consumption is reduced by 8%; there is no speed-up gear in the middle, which has higher efficiency and better reliability. Long, the design maximum pressure can reach 40bar.

  • 2. Two-stage compression; Select famous engines such as Deutz, Cummins, Yuchai World, etc.

  • 3.SKF bearing, direct drive, noiseless gear, design life more than 15 years;

  • 4. Good adaptability, it can automatically adjust the diesel oil valve (displacement volume) according to the gas consumption, without wasting a drop of diesel. This is equivalent to the frequency conversion control of the electric screw machine.

  • 5. The patented cyclone air pre-filter increases the number of air filter replacements by 5 times. The cyclone air filter filters residual dust and protects the compressor, and the filter element provides safe air filter maintenance without stopping the compressor. The system can operate continuously in desert conditions or heavy dust conditions. Accuracy up to 8μ. Compressed air triple oil cooling system, always saves no more than 3 ppm of oil in the exhaust compressed air.

  • 6. Automatic fuel supply for a long time - The large capacity fuel tank (up to 708 liters) enables large air compressors to work in remote areas without refueling.

  • 7. Versatile - suitable for use in all weather conditions and temperatures between -25°C/-13°F and +50°C/+122°F.

  • 8. Additional coolers, mufflers, low temperature starting systems, air tools, etc. (optional)

Two-stage air compressors are widely used in mining, water conservancy, transportation, shipbuilding, urban construction, energy, military and other industries that need to drill deep holes.

Airera high pressure double stage portable compressor comes into being. With multiple pressure and temperature sensors are set up in the unit to monitor the relevant parameters, and calculate and execute a reasonable fuel injection amount through the engine ECU and controller, so as to accurately guarantee the gas production and high wind speed at all times. pressure to ensure high penetration of the rig.

The higher the pressure, the faster the speed, while the high flow rate ensures large drilling diameter formation. In the long-term high temperature test, Fidelity equipment maintains consistent and stable performance, providing reliable, unchanged, constant productivity.
