Module 1-1 | Why bins Plug

• The three root causes of bin plugging: 1) poor bin geometry, 2) compaction by the feeder, and 3) uneven discharge.

• Material flow properties and good bin geometry in plain English.

• Mass flow and funnel flow

• Effective discharge area

Module 1-2 | The Six Decisions of Good Bin
and Feeder Design

Six key design decisions to ensure your storage bin can discharge using gravity:

• Flow pattern

• Bin shape

• Discharge outlet

• Angle of sloping walls

• Liner on sloping walls

• Effective discharge area

Module 2-1 | The Physics of Flow Patterns

• How gravity and friction determine a bulk solid’s flow pattern during discharge.

• Mass flow and funnel flow

Module 2-2 | Designing for Mass Flow: Bin Angle

• Determining the minimum bin wall angle to achieve a mass flow discharge pattern

• Wall friction angle

• The role of the shape of the bin

Module 2-3 | Designing for Mass Flow: Discharge Outlet

• The Bridging Dimension: the minimum discharge outlet needed to ensure that the force supplied by gravity is sufficient to prevent chronic bridging over the feeder

• Effective discharge area and the importance of a “fully-effective” Feeder.

Module 2-4 | Designing for Funnel Flow When Handling a Difficult Flowing Material

• The Piping Dimension: the minimum discharge outlet needed to ensure that the force supplied by gravity is sufficient to prevent chronic rat-holing over the feeder.

• Effective discharge area and long and wide openings

Module 2-5 | Strengths and Weaknesses of Mass Flow and Funnel Flow

• Shallow storage bin

• Lower bin wall pressures

• Natural liner

• First-in, last-out flow pattern

• Minimum effective discharge outlet can be very big

• Need to fully empty on a regular basis Mass Flow:

• First-in, first-out discharge

• Minimum discharge outlet is reasonable

• Taller bin with higher bin wall pressures and more abrasion along bin walls

• More expensive

• Require a fully-effective discharge outlet

Module 2-6 | Effective Discharge Area and Minimum Outlet

• Material compacts into arches as it descends down a converging storage bin

• The arch over the Feeder is both the weakest but also the most susceptible to becoming stable – which results in bridging over the Feeder.

• The span of the arch: ensuring gravity will reliably keep material flowing

• Effective outlet / effective discharge area and the behavior of the Feeder

Module 2-7 | Effective Discharge Area and Mass Flow

• If the discharge outlet of the storage bin is not fully effective, you will not get mass flow, why?

• As soon as you interrupt the flow of material from any part of the discharge outlet, the flow pattern switches to funnel flow regardless of the bin geometry.
