Over the past few years, inspectors in the cement industry have been discovering major advantages by using indoor drones to gather visual data. These devices are becoming an essential tool for ensuring safety, efficiency, and accuracy during internal inspections.
Indoor drones are particularly well-suited for inspecting critical assets such as cyclones, slurry tanks, silos, and kilns. Traditionally, these inspections required workers to enter confined spaces, often with the help of scaffolding or rope access. This process was not only time-consuming but also posed significant safety risks. Now, with the use of high-quality indoor drones, inspectors can collect detailed visual data remotely, reducing the need for physical entry into hazardous environments.
Here are some key assets that benefit from drone inspections in cement plants:
- Cement and clinker silos
- Slurry tanks
- Cyclones
- Tertiary air ducts
- Kilns
- Storage units
- Conveyor belts
Instead of climbing scaffolding or navigating tight spaces, inspectors can now send a drone inside. This change has led to numerous benefits, including improved safety, cost savings, and faster inspection times.
One of the most important advantages is **safety**. Inspecting large or confined areas often puts workers at risk of injury or worse. Drones eliminate this danger by allowing inspectors to stay outside while collecting data. For example, when a defect is found, workers only need to enter the asset briefly, knowing exactly where to focus their efforts.
Another major benefit is **cost savings**. A global cement company recently saved $50,000 on a single inspection by using a drone instead of scaffolding. Drones reduce downtime by eliminating the need for setup and teardown, and they speed up the inspection process significantly.
Drones also offer **better access** to hard-to-reach areas. Some parts of cement plant equipment are too narrow or dangerous for humans to reach. Drones equipped with protective cages can navigate these spaces, providing clear visuals of potential issues that might otherwise go unnoticed.
The **quality of visual data** collected by drones is another game-changer. High-resolution cameras allow inspectors to spot even the smallest defects, like cracks or loose bolts, which could lead to bigger problems if left unchecked. In one case, a drone flying near a slurry tank’s agitator arm captured details so clear that it confirmed the arm was safe for continued use.
In addition to improving planned inspections, drones enable **more frequent checks**. With quick “spot check†flights, plant managers can monitor conditions in real time, leading to better decision-making and increased productivity.
For those looking to start using indoor drones, here are a few best practices:
- Use **fishing line** to secure the drone, especially in dusty environments. Make sure the line can support the drone's weight.
- Keep **flights short** to minimize dust disturbance and maintain visibility.
- Always **clean the drone** after each flight to prevent dust buildup, which can damage components over time.
By adopting indoor drones, cement plants can enhance safety, cut costs, and improve the overall quality of their maintenance processes. It's a smart move that aligns with modern industrial trends toward automation and efficiency.
