Columbian TecTank™ can have your product tested through a proprietary consultant (Solids Handling Technologies (SHT)) for flow characteristics and incorporate the consultant’s recommendations into the tank design. Working with customer-supplied samples, we can produce dry bulk storage silos with predictable and reliable flow, even for hard to flow products.
These value added engineered flow services are available to any Columbian TecTank™ customer. As leaders in dry bulk storage, we maintain historical data on a wide variety of products. This information provides us with a better starting point for considering the flow characteristics of your specific product. Our experience with flowable materials is often applicable, even if you are storing new, proprietary materials with unique flow properties.
Your product testing will be conducted on a state-of-the-art shear tester, allowing SHT to predict material flow properties as they pertain to tanks and hoppers. They measure the cohesive strength of a solid to determine the opening required to prevent arching and ratholing. Additionally, they measure wall friction values to determine the required hopper slope for functional mass flow.
With accurate test results, Columbian TecTank™ can design silos for your desired product discharge characteristics. Let down chutes can be engineered and installed in silos to minimize product degradation. To minimize product segregation, we often employ functional mass flow chisel hoppers. First in/first out flow, multiple discharge streams and inverted cones in the hopper are other aids we recommend for specific situations to produce reliable flow.
Using our product testing equipment and an existing information database, we can design your silo to accept these passive flow controls. Internal drag and mass flow design loads are incorporated into the tank design. Columbian TecTank™ will custom design, manufacture and deliver your reliable flow silo to provide value-engineered solutions to your flow problems.
