The reliable storage and flow of bulk materials requires a comprehensive design process and good understanding of the flow properties of a bulk material. Analytical and empirical design techniques form the backbone of many design processes as they have been validated by research, however, theories based on continuum mechanics have many shortcomings and are restricted to 2-D analysis. Discrete element modelling (DEM) is proving to be a popular analysis and simulation method to verify designs for a wide range of bulk material processing and handling operations, such as transfer chutes. With the advances in computing and DEM technology, DEM has …

Conveyor transfer stations play a key role in many industries that handle bulk materials. Transfer stations can be rather sensitive to changes in material properties and can lead to relentless problems regarding reliability, wear, bottlenecking and blockages. Wet and sticky ores are typically difficult to handle materials due to their obnoxious ability to form a cohesive arch, adhere to surfaces and poor flow ability. Mines that are situated in areas with seasonal high rainfalls or that have started to exploit newer and more difficult to mine and handle ores, often from below the water table, experience vast difficulty in reliably …

A range of Ultra-Thin Cast Strip (UCS) sheet steels with elevated residual levels was produced via the CASTRIP twin drum casting method at Nucor Steel, Indiana. This paper examines the influence of elevated levels of copper, chromium, nickel, and phosphorous on mechanical properties, surface quality, processing, and weldability of UCS sheet steel products produced by the CASTRIP process. Increased levels of copper and phosphorous were found to strengthen UCS sheet steel due to solid solution strengthening but chromium and nickel did not. At lower coiling temperatures and low hot reductions, where processing conditions promote microstructural strengthening, copper and chromium further …
