The basics of solids flow

Lecture 6

In Lecture 6, Flow Aid Devices, Joe Marinelli of Solids Handling Technologies explores the area of flow aid devices that can be used to enhance or encourage flow from bins and hoppers.  Although our lecture series concentrates on primarily using gravity to pull material from bins and hoppers, sometimes gravity needs help.  Flow aids are intended to assist gravity by overcoming arching and ratholing problems.

Topics covered in this lecture include vibratory type devices such as bin dischargers and vibrators along with those that agitate product.  As well, forced extraction equipment such as silo bottom reclaimers and fluidization is discussed along with the availability of flow aid additives and chemicals.

Joe describes the equipment available within each of these categories and provides insight as to whether the devices discussed are practical, reliable and more importantly effective.  This lecture will ensure that if flow aids are warranted, you will make the correct decision in purchasing and installing them.

 The online video class is given along with handouts of the presentation and a quiz that will help to ensure your complete understanding of the concepts. Upon purchase of the course you will have 3 days to view the course before your access expires.
