Observation of a bulk material discharging from a hopper or flowing under gravity along a steeply inclined channel will immediately suggest similarities to the behaviour of liquids. Whilst there are certainly some similarities between the flow characteristics of bulk solids

Numerische Methoden der Analysisesigners and operators of bulk handling systems have recently become increasingly aware of the hazards associated with the release of airborne dust in significant quantities. Thus, whereas the principal incentive for the control of dust emissions used to be an economic one (i.e. the more valuable th

Dietmar Dorninger,Günther Karigl inclines. For example, whereas a conventional belt conveyor would generally be limited to a slope of about 20°, texturing the surface of the rubber belt to incorporate moulded ribs or nubs will allow conveying up an incline of some 60–70°, or even more, depending upon the nature of the bulk solid b

A fundamental feature of the original pattern of Archimedean screw which distinguishes it from other types of screw conveyor is that the helic

Mathematik für Wirtschaftsingenieure 1volved in bulk materials handling will be aware of vibratory conveying as a useful technique, few have the necessary understanding of this method to be able to design or select a system with confidence. However, there is little doubt that vibratory conveyors have some useful advantages, and an insig
