Particle Processing

Description

Teaches students the fundamentals of particle processing technology and characterisation, including measurement of particle characteristics, particle packing, segregation and sampling, storage and transporting of particles. Students also learn the unit operations associated with particle processing which include comminution and grinding, flocculation, agglomeration and granulation, particle separations, and paste extrusion. Finally some advanced topics in particulate processing are covered, including surface chemistry interactions, adsorption and surfactants, colloidal suspensions emulsions and rheology of suspensions. These principles will be applied to a range of industrially important processes including, minerals processing, ceramics processing, paints, food processing, and pharmaceuticals by the use of examples and problem solving.
