Graphical Selection of Sieve Mesh for Grain Sieves

Abstract

A graphical method was established to obtain the accurate screen apertures of sieves used for separating grain seeds from foreign matter at maximum efficiency thereby facilitating the proper design of a cleaning system. The method depends upon the statistical analysis of the physical/mechanical properties of both grain seeds and foreign matter, taking into consideration that these properties such as the linear dimensions, may be considered as variables which follow the law of normal distribution.
