Cardox CO2 blasting

Non-explosive Solution for Buildup & Blockage Clearing in Silo & Hopper & Rotary Kiln

 

Cardox CO₂ blasting system offers a powerful, straight shot solution to clear stubborn rock-hard material without damaging equipment or risking worker safety. It can effectively clear obstacles and remove buildup to restore material flow, optimize processing stream and maintain continuous production.

 

 

How Does Cardox System Work?

 

Cardox CO2 system uses a reusable steel tube filled with liquid CO2 and a heater element. When activated by a small electrical charge, heater rapidly converts the liquid CO2 to gas, increasing its volume to 500~600 times and creating high pressure up to 3000bar. This pressure bursts a rupture disc, releasing a high-velocity jet of inert gas that dislodges and breaks up tons of materials.

 

1. Loading – Liquid CO2 is charged into Cardox tube.
2. Insertion – CO₂ tube is placed near the blockage.
3. Activation – Electrically ignited, CO₂ rapidly expands (up to 3000bar).
4. Blasting – Rupture disc is broken, sudden gas expansion fractures and loosens material.
5. Material Dislodged – Gravity pulls fractured material down for smooth flow.

 

 

Cardox CO2 blasting system provides a safer and more controlled method for breaking down materials and clearing blockages in a wide range of industrial and construction applications, particularly where traditional methods are not suitable due to safety or operational constraints.

 

• Mining & Quarrying
  Cardox is used to break up ores, especially in areas where explosive blasting is risky or prohibited.

 

• Tunnelling and trenching
  Clearing blockages in shafts and tunnels: It helps remove obstructions in shafts, tunnels, trenches and other underground excavations.

 

• Underwater excavation
  Cardox can be used for breaking up rock and concrete underwater.

 

• Cement industry
  Cardox can eliminate rotary kiln rings or buildup in preheater, cyclone, cement silo, feed pipe, etc.
  Snowmen at clinker cooler can be removed effectively.

 

Benefits of Cardox System

 

• Online clearing to reduce costly downtime and keep full operation, even in high temperature areas.
• Controlled release of CO2 from directional discharge hole, no damage to silo & hopper structure.
• Safe operation with remote detonator. Labors don’t need to enter hard-to-access area.
• Refillable and reusable Cardox tube makes it economical blasting solution.
• Instantaneous phase transition of inert gas make it safe and non-contaminating.
