Title: Effect of the medium’s density on the hydrocyclonic separation of waste plastics with different densities

Abstract

Highlights: • The density of medium is the key parameter to separate plastic particles. • The paper shows the theoretical analysis is in good agreement with test. • The optimum value of the medium’s density was obtained. • The optimum value of the medium’s density lies near that of denser particles. - Abstract: Hydrocyclones can be applied to recycle waste plastics with different densities through separating plastics based on their differences in densities. In the process, the medium density is one of key parameters and the value of the medium’s density is not just the average of the density of two kinds of plastics separated. Based on the force analysis and establishing the equation of motion of particles in the hydrocyclone, a formula to calculate the optimum separation medium density has been deduced. This value of the medium’s density is a function of various parameters including the diameter, density, radial position and tangential velocity of particles, and viscosity of the medium. Tests on the separation performance of the hydrocyclone has been conducted with PET and PVC particles. The theoretical result appeared to be in good agreement with experimental results.
