Automatic air cannon AIRCHOC® DN150

remotely controlledfor cement productionfor preheaters

Problem
Build-ups in the preheating tower at the kiln inlet, smoke box, riser duct and bypass required around 8 hours of cleaning per day using high-pressure and Cardox methods.

Objective
Eliminate concretion that disrupts the industrial process and reduces production capacity, enabling safer and more continuous kiln operation.

Solution
Installation of 85 AIRCHOC® DN150 air cannons with remote solenoid valves and 2 MACSYS control units to automate and target impact zones.

Result

• No more build-up in the treated zones
• Increased use of alternative fuels due to improved flow and reduced risk of blockages
• Rapid return on investment and significantly reduced manual cleaning time
