Maximizing efficiency and cost-effectiveness
In the ever-evolving world of bulk materials handling, flexibility and efficiency are now key to competitiveness. Cement terminals, ports, and distribution facilities face constant pressure to reduce operational costs, maximise uptime, and ensure safety in demanding industrial environments.
Addressing these priorities head-on, WAM Trading Romania has launched in its market a new modular cement storage system that sets new benchmarks for capacity, flexibility, and reliability.
A NEW GENERATION OF CEMENT STORAGE
At the heart of this innovation lies a battery of four silos, each providing 125m³ of storage capacity, for a total of 500m³ per battery. Considering an average bulk density of 1.4 tonnes per cubic metre, the system delivers a total storage capacity of 700 tonnes — an impressive 40% increase compared to conventional 500 tonnes single-silo configurations.
This gain is achieved while occupying less ground space, reducing the need for concrete foundations, and cutting overall construction costs.
Beyond increased capacity, the modular concept introduced by WAM Trading Romania delivers operational flexibility that a single large silo cannot match. The four silos are arranged into two independent discharge lines, each fitted with a trough screw conveyor capable of extracting material from two silos, at a rate of 80m³/h (112 tonnes per hour) per line. This design ensures continuous operation, even when one line is undergoing maintenance — a significant advantage in sectors where downtime means immediate loss of productivity.
DOUBLING CAPACITY THROUGH SMART DESIGN
A standout feature of the system is its rotating screw option. Each screw can be turned 180°, effectively doubling the discharge capacity to 160m³/h, outperform ing conventional solutions.
This flexibility allows operators to respond dynamically to variable loading demands, optimizing performance during peak operations.
The modular arrangement also enables simultaneous storage of two different types of cement — for example, white cement in two silos (250m³ per line) and grey cement in the remaining two (250m³ per line). In contrast, a traditional single-silo system can only store one product at a time after being completely emptied.
This feature offers major logistical advantages for multi-product terminals, allowing quick product changeovers and improved inventory management.
CONTINUOUS OPERATION, SIMPLIFIED MAINTENANCE
Maintenance efficiency is another area where modular battery silos stand out. Thanks to the dual-line configuration, one line can remain fully operational while the other undergoes maintenance, ensuring uninterrupted workflow and product flow continuity.
Additionally, the low inclination of the trough screws offers tangible operational benefits. Their geometry allows easy access and straightforward cleaning in the event of material blockages caused by variable grain size or moisture content.
The use of trough screws instead of steeply inclined tubular conveyors represents a huge advantage in reliability and maintenance, reducing intervention times and ensuring smoother performance.
DESIGNED FOR SAFETY AND STRUCTURAL INTEGRITY
Safety and durability are cornerstones of WAMGROUP’s engineering philosophy. The new modular battery system comes with certified seismic design document ation for zone 2 (PGA 0.25), ensuring robust structural integrity in earthquake-prone areas.
The compact footprint of the installation reduces the number of concrete foundations required, resulting in lower civil engineering costs and a quicker, more efficient construction process.
The lighter structural design also simplifies project execution and shortens commissioning time, without compromising strength or longevity.
EVERY COMPONENT, 100% WAMGROUP
Every silo within the system is fully equipped with premium WAMGROUP components, ensuring a consistent level of quality, safety, and performance throughout. Among the key elements included are:
- SILOTOP® Zero and SILOTOP® vPolyTUBE silo venting filters, for maximum filtration performance with minimum energy consumption.
- Pressure Relief Valves VCP/VHS, vensuring safe pressure control.
- Level Indicators ILT for precise material monitoring.
- DUPLOCON® and FLOWAIDS for efficient cement discharge from silos in concrete and dry premixed material processing plants.
- Slide Gate Valves VIB for controlled flow discharge.
- Zero-Emission Loading Bellows, remotely actuated for clean and efficient truck and barge loading.
- Silo Safety System KCS for comprehensive operational protection.
Every component is manufactured by WAMGROUP, reaffirming the company’s commitment to in-house quality, advanced design, and system compatibility.
A COST-EFFICIENT AND FAST-TRACK SOLUTION
The modular battery silo concept stands out not only for its engineering but also for its economic advantages. The reduced footprint and optimised layout lead to lower construction and installation costs, making it the most cost-effective solution in its class.
Equally important, the system’s modularity and standardization allow for short lead times, enabling faster project delivery — a key advantage for customers seeking to expand or modernize facilities within tight schedules.
PROVEN RESULTS IN THE FIELD
This solution is already proving its value in real-world installations in Romania and Bulgaria, including at the ports of Burgas and Varna and in Frătești, where it has demonstrated outstanding operational efficiency, safety, and reliability under demanding conditions.
These achievements highlight WAM Trading Romania’s pioneering role in bringing this next-generation modular storage concept to the local market and providing comprehensive technical assistance — from project design through installation and start-up.
Their deep understanding of customer needs and on-site realities ensures that each project is executed with precision and attention to detail.
CONCLUSION
With its four-silo modular storage system, WAM Trading Romania has delivered a technological leap forward for the cement storage — combining greater capacity, dual-line flexibility, enhanced safety, and ease of maintenance, all while reducing installation costs and footprint.
In an industry where every tonne and every hour counts, WAMGROUP once again demonstrates the value of its philosophy in the building & construction industry: Smart Engineering for a Cleaner, More Efficient Future.
Robust, reliable, and remarkably adaptable, this new generation of modular storage systems proves why WAMGROUP — and its subsidiaries such as WAM Trading Romania — continue to set the benchmark for innovation in bulk material handling worldwide.
