Mining Liquid Oxygen Plant

China Liquid Oxygen Plant Manufacturer

 

Why Mining Industry Needs Liquid Oxygen Plant?
 

●Boost Blasting Efficiency:
Oxygen-enriched blasting increases the combustion rate of explosives by 40%, enhances fragmentation effect, reduces rock block size by 30%, and improves loading and transportation efficiency.
●Ensure Underground Safety:
Supply oxygen to underground confined spaces and high-altitude mining areas, increasing oxygen concentration in air to ≥21%, preventing hypoxia accidents of operators.
●Reduce Blasting Costs:
Oxygen replaces part of explosives, reducing explosive consumption by 15%-20%, and decreasing the generation of toxic gases like nitrogen oxide, lowering environmental treatment costs.
●Adapt to Remote Supply:
On-site liquid oxygen production avoids the high cost and transportation risk of long-distance tank truck transportation to remote mining areas, ensuring

continuous oxygen supply.

●Customizable Output:
Daily output can be customized from 3 to 30 TPD according to the scale of mining face and blasting frequency, avoiding resource waste.

Q: Is the plant suitable for high-altitude mining areas above 3000 meters?
A: Yes, it is equipped with altitude-adaptive components, which can adjust the air compression parameters according to the altitude, ensuring stable output and purity in low-air-pressure environments.

Q: How to transport the modular components to the remote mountain mining area?
A: Components are designed with small size and light weight, suitable for transportation by mining trucks, tractors or even cableways; vulnerable parts are equipped with shock-proof packaging.
 

Q: What is the power supply requirement for the plant in the field?
A: It supports 380V industrial power supply and can be matched with diesel generator sets for areas without grid coverage, ensuring independent operation.
 

Q: How to maintain the equipment in the harsh underground mining environment?
A: We provide maintenance toolkits and video guidance, and the key components have self-diagnosis functions; on-site maintenance personnel only need simple training to complete routine maintenance.

Q: Can the plant supply oxygen for both open-pit and underground mining at the same time?
A: Yes, it is equipped with multiple output pipelines, which can be connected to open-pit blasting points and underground ventilation systems respectively, and the flow can be adjusted independently to meet different demands.
