Course description
The issue of de-blending (segregation) of bulk particulates is one that afflicts many diverse industry sectors. For single materials and blended materials the presence of segregation within a process can be apparent as fluctuations in bulk density, chemical composition, shifts in size distribution or even unpredictable flowability issues. These types of problems invariably lead to the generation of waste through out of range product weights (tablets/ pack fill), poor processing characteristics or variable quality end products in general.
This short course covers:
Identification of the most commonly encountered segregation mechanisms
Examples of how segregation has occurred in plant
Techniques that can be applied in plant design to minimise these effects
Different types of segregation will also be identified; air-induced, rolling, surface effect, percolation.
During the course discussions will take place to highlight material types that are most at risk of segregation and the most commonly encountered mechanisms of segregation in process plants. The influence of plant design and operation on the severity of de-blending will be covered and the use of counter measures will be dealt with and illustrated using industrial examples.
