The NEW UltraQuiet ™ Mary Ann® Laboratory Sifter continues to be the industry standard for accurately sifting aggregates into proper particle sizes. The new generation Mary Ann units are UltraQuiet™, with wheels for easy relocation and a SieveRack™ under the unit for easy storage of sieves. Inside a handmade enclosure 8” or 12” sieves can be stacked up to 26” in height and placed inside the Mary Ann without clamping. The inclined, rotating stack of sieves provides a gentle and thorough tumbling action, which allows the particles to pass through the mesh. The sifting process is repeated on the smaller meshed sieve—and so on down through the stack.
