Description: This first lecture, in the Solids Flow Series, will cover basic solids flow problems, the effects of those flow problems in your process or system, and flow patterns. Flow problems in your handling system can have serious consequences, where reliable solids flow is essential, especially with regard to operational costs and downtime.

Some of the topics discussed include arching, ratholing, flooding and segregation issues. Joe Marinelli also discusses the effects of limited live storage, spoilage or caking and even structural concerns. The advantages and disadvantages of flow patterns such as funnel flow and mass flow are also demonstrated.

Lecture includes downloadable class notes and a self administered quiz with answer sheet. The three-day subscription allows you to watch and review this video class as many times as you need.

  Lecture 2:  Design principles for reliable flow - wall friction, flow functions, bin design parameters

  Lecture 3:  Feeders, both volumetric and gravimetric - volumetric screws, belts, rotary valves, plus
                    gravimetric & loss-in-weight feeders 

  Lecture 4:  Measuring bulk solids flow properties - shear testing, variables that affect properties

  Lecture 5:  Particle segregation - segregation mechanisms, solutions to common problems

  Lecture 6:  Flow aid devices - assistance to gravity flow, air blasters, vibration & fluidization
                    techniques  (Available August '09)

  Lecture 7:  Hopper retrofits to existing systems - cones vs. wedges, hopper liners & special inserts
                    (Available August '09)

  Lecture 8:  Design examples - determining hopper geometries using the Jenike approach
                    (Available August '09)
