Abstract

Wall pressure and flow rate during discharge of granular materials from a bin-hopper system were measured to discuss the validity of a proposed mechanical model on granular flow in a bin-hopper system. The measured values agree well with the calculated ones based on the model. This shows that the model is applicable to the mechanical analysis of flowing granular materials in a bin-hopper system. The mechanical model is applicable to the estimation of flow rate of granular materials discharging through an orifice, and the dependence of the height of powder bed in a hopper and diameter of orifice on flow rate is discussed.
