Exploring the influence of feed material properties on full cycle optimisation of fill, squeeze and blow plate and frame pressure filters

Abstract

Investigation of the response of plate and frame filter performance to changes in design and operating variables is complicated by the large matrix of potential variables and the inter-dependent kinetics of the fill, press and air blow stages. However, through some key simplifying constraints an integrated optimisation framework has been recently developed 1. Initial demonstration of the utility of the framework for minerals filtration was completed on an incompressible iron ore fines material which illustrated a strong dependency of the optimum filling duration on filter specifications such as the ratio of pressing to filling pressure and cavity thickness employed. The current paper extends..
