Modelling the banana screen. The flow of material on the screen deck is modelled by introducing small discrete zones, see Fig. 1. In order to model the mass flow the particle size distribution is divided in small sub fractions j, in every sub fraction all particles are assumed to be of equal size. Between the discrete zones mass is …

In a comparison between a screen with only one angle of incline in this paper referred to as a reference screen (with constant angle of incline set to 15 degrees) and a banana screen it can be shown that the screening efficiency is higher for the banana screen.In Fig. 3 a principal comparison is shown between the mentioned screen …

A variable slope screen with a hole structure was designed to improve the cleaning performance of maize cleaning devices. The movement behaviour and sieving performance of maize mixture particles on the new and traditional screens were quantified using relative migration and through-screen mass ratio coefficients.

This paper carried out the numerical simulation about the movement of non-spherical particles on banana vibrating screen using direct element method (DEM) considering the complexity of particle collision and avoiding obtaining motion information with difficulty.
