Typically, a spiral channel severs which opens upwards and allows the material to flow down with turn. This device has a spiral shape that can be used for the separation of the particles due to the force of centrifugal and gravity. This method works especially well for fine and granular materials like Iron ore, Chromium and Zircon.

First, ore flow stream turbulence was quantified with a mathematical model that determined velocity and pressure gradients in contact between ore and chute, and ore and belt. It followed that the chute could minimise damaging velocity and pressure gradients. A curved chute profile is presented which meets these objectives.

During the flow of iron ore in hoppers or high-throughput chutes with a wider range of particle sizes, the larger particles generally move bodily while the fines shear across themselves. Therefore, the bulk strength of the iron ore material and the associated risk of flow stoppages is dependent on the strength of the fines component. As a
