Mass Flow Storage Systems
Tank Connection — The Experts in Mass Flow Storage Systems
A Simple Fact: At TCAG, we build more functional mass flow storage systems than any other manufacturer in North America.
At Tank Connection, we are recognized as the design and fabrication experts for functional mass flow storage systems. Based on a sample of your material tested on a Jenike Shear Tester, Tank Connection can design a functional mass flow storage system that will provide consistent, reliable performance in the field. And we back it with a performance guarantee.
By definition:
- Funnel Flow for Dry Bulk
- Stored product discharges from a storage tank in a funnel flow/channel, which typically forms in the center of the tank. Stored product discharge is “last in/first out” (LIFO). Segregation of product occurs during discharge.
- Mass Flow for Dry Bulk
- Every particle is in some degree of motion during discharge. Stored product discharge is "first in/first out" (FIFO). Mass flow minimizes segregation of product during discharge.
- Mass Flow Storage System Design
- A storage tank design that will withstand mass flow discharge conditions if they occur. A mass flow design does not guarantee functional mass flow discharge from the tank.
- Functional Mass Flow Storage System Design
- A storage tank design that guarantees the stored product will functionally mass flow during discharge.
A common mistake:
A common mistake made in today's dry bulk storage market is to specify a mass flow tank design. If true mass flow is a requirement in your discharge stream from the storage tank, the correct parameter to specify is a functional mass flow storage system.
Tank Connection solutions:
Based on independent testing conducted by Solids Handling Technologies, Tank Connection's Fusion 5000 FBE™ coating system yielded superior “flow promotion” qualities for dry bulk materials. Flow testing depicts that functional mass flow discharge can be achieved with reduced hopper slopes by utilizing Tank Connection's proprietary fusion bond system. Reduced hopper slopes equate to cost savings for the client. (Note: Joe Marinelli at Solids Handling Technologies is recognized as one of the top flow consultants worldwide.)
Storage Systems: Various Dry Bulk Materials
Interior Coating System Tested: Fusion 5000 FBE™ (fusion bond epoxy) System
Example: Stoker coal will functionally mass flow utilizing a 63° carbon steel hopper that is coated with Fusion 5000 FBE™. The same results can be achieved by utilizing a 69° hopper constructed of 304 stainless steel with a 2B finish. Similarly, a 77° hopper slope is required for functional mass flow from an uncoated carbon steel hopper.
