The working process of a suspended vibratory conical sieve. Experimental research

      Аннотация: Separation of granular products on sieves with oscillatory motion can be appreciated with the aid of three curves: distribution curve of material separated for each area of the sieve; cumulative percentage curve of granular material separated on the length of the sieve; cumulative percentage curve of unseparated material on the length of the sieve. If the separation sieve is a conical one with a vertical shaft and alternative oscillatory motion in horizontally plane, separation of granular material is estimated on the base of the cone radius. Depending on the movement kinematic parameters and functional parameters of the sieve, those three separate curves can have different profiles. Thus at a conical sieve with circular apertures were analyzed differences between curves profiles depending on the amplitude and frequency of the oscillation movement and flow of material feed. Sieve was used to separate large impurities from rapeseed, character of material movement on sieve being appreciated by separating profile curves
