Abstract

Abstract

In order to improve the particle mixing effect in the soil integrator system, a numerical model of the mixing process with contaminated soil and remediation chemicals powder particles was developed based on the mixing kinetics principle and the discrete element method (DEM). The interaction and number of collisions between discrete particles and mixing components in the system were analyzed; the mixing uniformity and quality evaluation formulae were designed to evaluate the mixing efficiency. The influence of soil particle size and knife roller speed on the mixing uniformity of soil and remediation chemicals was analyzed quantitatively, which can provide technical guidance for improving the performance of the next-generation soil remediation all-in-one machines.
