ABSTRACT:
Particles flowing in a stream can be arranged in an order of classification extending transversely of the stream according to physical characteristics of the particles by self-screening and stratification which occur in response to a continuous vibratory feeding of the particles in a direction laterally of the direction of flow of the stream. Particles having similar physical characteristics will flow from a specific portion of the stream into a collecting receptacle having a plurality of compartments arranged in a line transversely of the stream for separately collecting as many stream portions as required to obtain the desired degrees of separation. Further particle assortment from each stream portion can be made in accordance with the particles trajectory of fall from the stream bed.
