?pARAMETRIC STUDY OF INCLINED PLANE SIEVING

Abstract

This paper presents the study of different parameters affecting the sieve fractionation of powders over an inclined
plane. In this investigation coal powder hasbeenused to seehow theshapeof the fineparticles modifiesthe behaviour
of the powder moving down the inclinedplane. It hasbeen indicated that the mean size of the fractions of the powder
passing through the sieve atdifferent anglesof inclination (8) isessentially constant andis independent of the amount
of the powder passed. The amount of powder passed through the sieves drops off drastically. In such a setup sieving
could be very quickly achieved in relatively shortdistances.This investigation wouldbe veryimportant in developing
automatic sieving procedures.
