Rotating Aggregate Sifter

The free-standing DuraShake with digital timer improves upon the methods of traditional shakers by offering a more natural, less severe sieving action.

Here, sieves are quietly and effi ciently rotated at an angle that ensures the sample is spread evenly across the mesh, and tapped individually by a series of nylon blocks — a method that closely matches the action of manual sieving.
 To operate, simply place the sieves in the chamber, tilt back, close door, select sieve size and set timer. The machine stops when fi nished, and also features a door safety shut-off. The DuraShake accepts up to ten 8" (203mm) diameter by 2" (50.8mm) high or six 12" (305mm) by 3" (76.2mm) high standard test sieves and cover.
