Other Lectures in the Joe Marinelli Solids Flow Series
Lecture 1:  Flow Problems – Their effects 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.. (click for more)
Lecture 2:  Design principles for reliable flow – wall friction, flow and bin design
Wall friction tests yielding the angle of wall friction, leads to determination of hopper angles required to ensure flow along the walls, which is mass flow.. (click for more)
Lecture 3:  Feeders, both volumetric and gravimetric
The key to reliable feeder design is to make sure that the feeder is capable of discharging your product uniformly over the entire outlet cross-sectional area.. (click for more)
Lecture 4:  Measuring bulk solids flow properties – shear testing
Wall friction tests are demonstrated using several wall surfaces, which lead to determining the hopper slope required to ensure flow along your hopper walls.. (click for more)
Lecture 5:  Particle segregation – segregation mechanisms and solutions
A detailed discussion of the mechanisms that cause segregation.  Segregation is a major problem in many industries such as pharmaceuticals, foods, batteries… (click for more)
Lecture 6:  Flow aid devices – assistance to gravity flow by various “flow aids”
This lecture explores the area of flow aid devices that can be used to enhance or encourage flow from bins and hoppers such as bin dischargers and… (click for more)
Lecture 7:  Hopper retrofits to existing systems – cones, wedges, liners & inserts
Geometry modifications are considered, such as wedge type hoppers, splitters and chutes. These modifications are practical and will resolve many flow… (click for more)
Lecture 8:  Design examples – determining hopper geometries
Joe uses the Jenike design approach to calculate opening sizes and hopper angles. Joe discusses minimum opening size calculations and hopper angles.. (click for more)
