New Modelling and Calculation Methods for Vibrating Screens and Separators

Abstract

This work reveals the authors’ experience in developing a fast-acting computational modelling algorithm and calculation of devices for vibrational size classification of ores, solid waste and other bulk materials. It is shown that adaptation of several analytical models to computing allows creating a new, less resource-intensive approach, as compared to widespread multi-functional computational methods (including DEM). This algorithm, based on problem-oriented models, requires neither preliminary calibration nor adjustment, which additionally reduces its deployment time and application costs. Moreover, the algorithm enables parcel-wise improvements, as illustrated by introduction of an advanced openings-passing model and a layer-based vibrational separation sub-model.
