SORTING PROCESS AND APPARATUS

摘要

For sorting particles of a mixed particulate material in dependence on their coefficients of sliding friction it is proposed that the particles are fed to a revolving endless belt, which has from the feed point to the downstream discharge edge a length portion having a length which in dependence on the velocity of the revolving belt is so determined that only those particles of the mixed material which have the highest coefficient of sliding friction will be accelerated to the velocity of the belt while moving on said length portion and that all particles having a relatively lower coefficient of sliding friction will have a lower velocity at the discharge edge 90 that the particles which have been discharged will fly along different trajectories and can be collected by correspondingly disposed devices.
