Overview
A large, highly automated ready-mix concrete operation supplying public and private construction projects identified a critical gap in its material handling process. While batching, dispatch, and quality controls were fully computerized, cement unloading still relied on a legacy system that no longer aligned with modern efficiency, reliability, and environmental standards.
To eliminate this bottleneck and support continuous plant operations, the producer partnered with Cyclonaire to modernize its cement railcar unloading and conveying process.
Challenges
The existing cement unloading system created several operational issues:
- Slow unloading caused by railcar positioning and gravity-fed pits
- Labor-intensive pit cleaning that exposed workers to dust and confined-space conditions
- Frequent downtime due to wear on mechanical conveying components
- High maintenance requirements and elevated energy usage
- Multiple blowers and complex controls increasing operating complexity
- An unloading process that lagged behind the plant’s otherwise advanced automation
The operation needed a cleaner, faster, and more reliable unloading solution that could integrate seamlessly with existing automated systems.
Solutions
Cyclonaire engineered a semi-dense phase pneumatic conveying system specifically designed for cement railcar unloading.
Key elements of the solution included:
- A vacuum-loaded Cyclonaire HC Series conveyor for unloading hopper-bottom railcars
- Automatic cycling between vacuum loading and pressurized conveying
- A single high-efficiency blower supplying both aeration and conveying air
- An over-the-rail adapter allowing multiple railcar hoppers to unload through a single connection
- Simple, automated controls requiring minimal operator involvement
- A system layout that eliminated the need for unloading pits and manual cleanup
The solution replaced mechanical conveying equipment with a streamlined pneumatic system that improved reliability and cleanliness.
Results
The Cyclonaire unloading system delivered clear operational improvements:
- Faster and more consistent cement unloading
- Elimination of pit cleaning and associated labor
- Significantly reduced dust and cleaner unloading areas
- Lower maintenance demands due to fewer wear components
- Simplified operation with fewer motors and controls
- Improved system uptime supporting uninterrupted concrete production
The success of the installation led the operation to plan Cyclonaire systems for future upgrades across additional unloading and storage facilities.
