Fluidised bed for stripping sand casting process

An innovative application of a non-traditional casting system, in particular a stripping fluidised bed, whose working principle is based on air - sand interaction phenomenon, is presented. A bed's prototype used to analyse the fluidisation phenomena is described. The purpose of the experimental tests is to measure: pressure, air flowrate and velocity. Different measurement points inside the prototype have been taken into account. Stripping pieces with different shapes and dimensions have been considered. Moreover visualisation of air bubbling in the sand is possible and its behaviour is compared to a computational fluid flow simulation.
