--- title: Air Cannon Solution Improves Safety and Prevents Preheater Blockages description: Learn how JK Cement Works in India improved safety, reduced maintenance labor, and eliminated dangerous manual cleaning in a preheater tower using Martin® Typhoon Air Cannons and SMART™ Series Jet Nozzles. image: https://static.martin-eng.com/www.martin-eng.com/case-studies/JK%20Cement%20Works%20IMG-20190305-WA0039%20%28002%29.jpg --- [Skip to content](https://blog.martin-eng.com/problem-solved-papers/air-cannon-solution-improves-safety-and-prevents-preheater-blockages#main-content) [![Martin Engineering](https://blog.martin-eng.com/hubfs/Martin%20Engineering%20Logos/martin-sig_white.png "Martin Engineering")](https://www.martin-eng.com/) ## Problem Solved Paper call 800.544.2947 # Air Cannon Solution Improves Safety and Prevents Preheater Blockages [Martin Engineering](https://blog.martin-eng.com/problem-solved-papers/author/martin-engineering) July 9 2026 [Material Flow Problems](https://blog.martin-eng.com/problem-solved-papers/tag/material-flow-problems) ### PROBLEM  ![](https://static.martin-eng.com/www.martin-eng.com/case-studies/JK%20Cement%20Works%20IMG-20190305-WA0039%20%28002%29.jpg)JK Cement Works in Northern India, producing 3.25 mt/y, was experiencing [clogging issues](https://foundations.martin-eng.com/knowledge/material-flow) in its preheater tower requiring manual cleaning of the feed pipe while the tower was in operation. The dangerous procedure used an air lance through an access hatch, which can result in extreme heat exposure, blowback, and potential contact with molten debris. Production demands prohibited managers from allowing downtime to fully clear the duct. This increased cleaning schedules, further exposed workers to danger, and pulled resources away from other essential tasks in the plant. The extra labor also increased the cost of operation, so managers sought a solution that allowed them to address the problem without downtime.   ### SOLUTION  ![](https://static.martin-eng.com/www.martin-eng.com/case-studies/JK%20Cement%20Works%20IMG_20190315_183027%20%28002%29.jpg)Technicians from Martin Engineering India were invited to examine the issue, and they decided to install two air cannons at the clogging point. Buildup is common in preheater towers and can take up to 10 days of downtime for cooling, cleaning, and reheating. By using a Martin® Core Gate, holes were carefully drilled through the refractory during operation, then the air cannon assemblies were installed. Using a 70L [Martin® Typhoon Air Cannon](https://www.martin-eng.com/content/product/149/typhoon-air-cannon) connected to the plant's compressed air system and a [SMART™ Series Jet Nozzle](https://www.martin-eng.com/content/product_subcategory/492/smart-series-air-cannon-nozzles) designed for high-temperature environments, each unit delivers a powerful shot of air that dislodges adhered material. The cannons were set to fire automatically at predefined intervals.  ### RESULTS  ![](https://static.martin-eng.com/tinymce/upload_5f206f11bf81d.jpg)The drilling and installation only took two hours. With the ability to service and maintain the valve and nozzle without removing the tank or assembly, a permanent solution was provided that significantly reduced maintenance labor while improving safety. Moreover, dislodging adhered material before it accumulates means the problem area no longer requires manual cleaning. "We have never seen this done in a running cement plant", said an operator close to the project. "We are very happy with the performance." Managers are now working with Martin Engineering India to install a similar air cannon solution in other parts of the tower and throughout the plant.  [![Keep Material Flowing with Air Cannons](https://no-cache.hubspot.com/cta/default/5156573/interactive-209999666291.png)](https://blog.martin-eng.com/hs/cta/wi/redirect?encryptedPayload=AVxigLLqv9B%2BAJfcNv9%2Bz7NukRayiDd9m%2BN76WcuuaIP5WDMnO8Md4rCPIh3yBqh32VfQxjdrkUtmG7F4woC13wRV%2BFi9U2oMSWJsRbiiNcYfKES8ahLQkzrC%2F6K1EzPgdJWUZnJRqOwy%2B8kK%2F5eqPsjyPOS5t5csbWwdQUmyKwdRVM23LTTe8obostbwxcybKTDounUbMiUJxxiP8gk&webInteractiveContentId=209999666291&portalId=5156573) [![Martin Engineering](https://blog.martin-eng.com/hubfs/Martin%20Engineering%20Logos/martin-sig-rgb_300px-wide.png "Martin Engineering")](https://www.martin-eng.com/) Martin Engineering is the world leader in making bulk materials handling cleaner, safer, and more productive since 1944. © 2025 Martin Engineering Company.
