Description:  In this first lecture of the Practical Overview of Pneumatic Conveying Series, Jack Hilbert of Pneumatic Conveying Consultants describes the applicability of pneumatic conveying to a multitude of uses and functionality within a plant.  Examples of in-plant applications are given as well as an overview of the typical industries which rely on pneumatic conveying.

The basic pneumatic conveying system is described as well as types and modes of pneumatic conveying systems along with the advantages, disadvantages and application criteria for each one. Moreover, key definitions to commonly used terminology are given.

The fundamental pressure vs. volume relationship is explained along with the generally accepted model for classifying materials.  Key physical material characteristics are defined and how they influence the selection and operation of a pneumatic conveying system are explored.

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

	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 vibrators.. (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 issues... (click for more)
