The Particle Problem….

O er !"# of industrial $rocesses in ol e $articles %&T

• The majority of particle handling and processing operationsare empirically designed

• Measurement and control is difficult and costly.• Simulation-based design no possible for particle systems

%ul( Handling E)ui$ment

• Ma%imising throughput & 'is# of spillage and bloc#age & E%cessive ear of e(uipment leading to higher replacement

costs and longer system do ntime

• )ealing ith variation in design and operating re(uirements & *sually bespo#e system designs & "ul# material behaviour usually varies ith type, origin and

environment• Testing prototypes and troubleshooting problems

& +ostly to build and test designs and e%plore design options & )ifficult to measure material-e(uipment interactions
