Abstract
Particles are fed for sorting by a radial distributor having an upper surface on which the particles gradually spread arcuately and are displaced radially outwardly, by for example vibration of the distributor, to a lip of the upper surface where they define one or more curved arrays as the fall over the lip. As they fall in free flight trajectory paths the particles present a curved array one particle deep to a separating device arranged to sort the particles according to the degree they possess a particular characteristic.
