The "Original Mary Ann" sieve sifter has been a standard of the industry for years. This totally-enclosed unit can be used with 8" or 12" sieves. Sieve stacks up to 26" (660mm) in height can be set into place quickly with no clamping needed. The Mary Ann design angles the sieves at 45° while rotation from a 1/3hp motor and tapping from hardwood-faced aluminum hammers promote action to accomplish the sieving process. The support stand also serves as a sieve storage rack. Assembled Sifter requires 18" x 40" (457 x1016mm) of floor space. Unit Dimensions: 18" x 26" x 58" (457 x 660 x 1473mm).
