Designing for impact damage and wear

A cyclone barrel’s 3D model was analysed with Finite Element Analysis and CFD to determine if it would be structurally adequate to resist the impact force associated with the air stream and ore particles in accordance with AS3990. By calculating a bulk density for the flow stream (which includes the air and the ore particles), the force acting on the plate was calculated. This force was then applied to the 3D model and FEA was used to evaluate the stresses and deflections.
