Abstract:
A method of screening material comprising the steps of providing a plurality of undulating screen assemblies each having ridges and troughs of substantially identical external cross sectional configurations with said ridges and troughs having first and second opposite ends, mounting said plurality of undulating screen assemblies in end-to-end adjacent relationship on the bed of a vibratory screening machine with said substantially identical external cross sectional configurations of said ridges and troughs of said plurality of undulating screen assemblies being in alignment, depositing material to be screened on one of said undulating screen assemblies, and causing said material deposited on said undulating screen assemblies to travel lengthwise of said aligned substantially identical external cross sectional configurations of said ridges and troughs of said plurality of screen assemblies and to pass continuously from at least one screen assembly onto the end of an adjacent screen assembly.
