英文摘要: Abstract(#br)The internal material transport and selection processes of the wet low-intensity magnetic separators (LIMS) are poorly understood; this calls for improved measurement techniques. In this work an ultrasonic velocity profiling (UVP) technique for measuring how material flow velocity varies with penetration depth is presented. A measurement depth of just a couple of centimetres would greatly improve the understanding of the separation process in a LIMS.(#br)When applied to flows of mineral suspensions with high volumetric solids concentration, similar to those in the separators, UVP is unique in combining: • Non-intrusive measurements. • Operates using just one sensor element (transducer). • Relatively good spatial resolution. • Penetrates opaque suspensions. • Fast sampling...
