Spiral Silo
Application Tips
Assessing the characteristics of bulk materials, storage capacity, and site conditions, we offer customized spiral silo solutions specific to cement, fly ash, grain and other bulk materials that are designed to fit your facility’s space and meet the load and operational constraints of your facility.
Our engineering team provides advanced safety solutions, such as explosion-proof design and corrosion-resistant materials (S350GD steel with Z275 galvanization), combined with the construction of pressure relief and anti-collapse systems. All of our solutions are built to international standards of industrial safety to eliminate the risk of collapse in hostile operational environments.
Our designs focus on the optimization of your bulk storage investments. Spiral silos save up to 25% land occupancy in comparison to standard silos. The long-term investment costs for the storage system are lowered due to minimal maintenance. The silos are constructed to be readily expandable and to have a lower operational burden, yielding a rapid return on investment.
Spiral Silo Design Guidelines for 8 Major Industries
Our Silo Solutions incorporate design and engineering factors that address the specific bulk storage requirements for each industry covering cement, power plant, grain, feed, chemical, food processing, construction, and mining industries.. Some of the design and engineering factors include capacity, silo sealing, and silo structure.
