Abstract

A flow diversion apparatus and method comprising a flow deflector (15) for intercepting a flow (13), such as a flow of bulk granular solids. The flow deflector (15) presents a curved deflector surface (17) having a centre of curvature (19). The flow deflector (15) is mounted for selective angular movement to rotate the curved deflector surface (17) about the centre of curvature (19). With this arrangement, the point at which the deflector surface (17) intercepts a flow (13) can be selectively varied by angular movement of the flow deflector (15) without varying the angle at which the deflector surface (17) intercepts the flow. With rotational movement, the curved deflector surface (17) can assume different orientations, and the intercepted flow (13) can be directed in different directions according to the orientation of the flow deflector (15).

Abstract

A transfer chute (10) for use in bulk materials handling operations, and also a methodology for designing such a transfer chute, a method of constructing the transfer chute, and a method of transferring bulk materials between two locations using the transfer chute. The transfer chute (10) comprises a chute body (11) defining a flow pathway (19), with an upper section (19a) of the flow pathway accommodating accelerating flow to maintain dense granular flow regime, an intermediate section (19b) of the flow pathway providing consolidated flow in which the flow rate is retarded in a controlled manner avoiding creation of flow turbulence, and a lower section (19c) of the flow pathway in which flow is further retarded to create a controlled accumulation and build-up of material upwardly from the lower section.
