A power driven oscillating sifter oscillated by a motor driven crank arm with the sifter having a pair of end plates and a central baffle all secured to the shaft. A perforated semi-cylindrical sifter panel is detachably secured to the end panels by means of inturned flanges on the end panels. The sifter panel has a plurality of longitudinally extending ribs for agitating the material to be sifted and openings are provided in the baffle and the lower end wall to permit the exit of materials which will not pass through the perforations of the sifter panel.
