Impact damage and wear of a cyclone barrel

Dynamic Engineering was asked to determine if a cyclone barrel was sufficiently strong enough without the use of an over centre clamp (which had failed). So the barrel had to be structurally strong enough to resist the impact forces associated with the air stream and ore particles (in accordance with AS3990). To ascertain this,  a 3D model was created and analysed with Finite Element Analysis and CFD. 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.
