Storage and feeding systems are essential to many process manufacturing operations, but designing them successfully requires more than selecting a vessel or installing a device at a hopper outlet. Material properties, flow patterns, storage conditions, and equipment interactions all influence system performance.

Join Scott Miller, consultant at Solids Handling Technologies, Inc., for an introduction to bulk-solids storage and feeding. This webinar examines five common misconceptions that can affect equipment design and operation, from assumptions about storage capacity and material flowability to misunderstandings about feeder function and the relationship between hoppers and feeders.

Through an overview of storage vessel fundamentals, flowability testing, discharge methods, and feeding technologies, you’ll learn which factors to consider when developing a design that meets process requirements.

What you’ll learn

• Storage capacity: Understand why live volume, rather than total available volume, determines a vessel’s usable capacity.
• Material flowability: Explore how stress, time at rest, moisture, temperature and other material characteristics can affect discharge.
• Flow testing: Learn how shear, wall friction and compressibility testing help establish a basis for storage vessel design.
• Feeder selection: Understand the difference between volumetric and gravimetric feeding and how accuracy, precision and turndown relate to feeder performance.
• Integrated system design: Discover why hoppers and feeders must work together to achieve reliable material discharge and controlled feeding.
