Chute flow patterns are described and the application of chute flow dynamics to the determination of the most appropriate chute profiles to achieve optimum flow is illustrated. The influence of the flow properties and chute flow dynamics in selecting the required geometry to minimise chute and belt wear at the feed point will be highlighted. 1.

Iron ore plugging would occur several times per shift, requiring operators to use high pressure water hoses to unplug the chute. At times, the iron ore was bone dry and dusty, leading to severe dust generation during handling in the chute. The iron ore is highly abrasive and would wear parts of the transfer chute that did not experience severe ...
