Abstract
Method and apparatus for separating granules of different sizes from a granular mixture, by combination of vertical size separation under vibration and horizontal flow. A horizontal base plate with an asymmetric saw-tooth upper profile is provided and a mixture of granules is fed onto the base plate. The base plate is then vertically vibrated, so as to separate the mixture into superimposed, partial layers of granules of different sizes, while horizontally advancing the same in opposite directions and separately collecting these layers.

Method for separating granules of different sizes from a granular mixture, by combination of vertical size separation under vibration and horizontal flow.
Apparatus for granular separation, which comprises:
- e) a base plate having a sawtooth upper profile;
- f) a vibrator or vibrators for causing said plate to vibrate vertically;
- g) a feeder, or feed mechanism, for feeding the granular mixture to be separated onto said base plate, so as to form a layer thereon;
- and
- h) means for separately collecting the superimposed partial layers of granules produced by the vibration of said base plate.
Method for separating granules of different sizes from a granular mixture, substantially as described and illustrated.
Apparatus for granular separation, substantially as described and illustrated.
