Abstract

Abstract : Purpose: The purpose of this paper is to design the geometrical structure of banana screen, and this study aims to improve the screen efficiency. Design/methodology/approach: The discrete element method was used to simulate the sieving process of banana screen with the inclinations of decks improved by Fibonacci sequence. The effect of each deck along screen length on the screening efficiency of particles was studied in this paper. Findings: The comparisons among three groups of industrial banana screens with five different consecutive Fibonacci numbers have been made, and the variations of fine particle ratio were also investigated. The results show that the banana screening improved by the 5 Fibonacci sequence, 3, 5, 8, 13 and 21, has the good screening performance in the simulation. It is found that the inclination degree of the first deck at the feed end is the key factor to determine screening efficiency of banana screens. Practical implications: It is not possible to consider all real physical factors exactly in a virtual model. The experiment prototype of banana screen was used to simply verify the feasibility of the methodology. Originality/value: This work is helpful for designing the geometric parameters of the curved screen and gives a broad perspective to improve the efficiency of banana screens.
