摘要：Erosion wear at the wetted passages is a critical parameter for selection and design ofslurry transportation systems. Erosion wear is a complex phenomenon and is difficult topredict for multi-sized particulate slurries mostly due to representation of itsdependence on a single particle size. In the present work, an effort has been made todevelop a methodology to determine the nominal particle size of multi-sized particulateslurry for estimation of mass loss due to the erosion wear. It is seen that a particle sizerepresenting the mass average of the particles can be taken as the nominal size. Theeffect of presence of fine particles (<75 μm) in relatively coarse particulate slurry hasalso been studied separately by conducting experiments in a pot tester. It is observedthat a reduction of approximately 40–50% in the wear is possible by addition of finerparticles 25% (w/w) of bigger particles.
