Rotary Sifters with Tapping have reliable, proven designs for efficient separations, and accommodate stacks up to 26in (660mm). Rotary Sifters are preferred by some state DOT’s for particle sizing of mineral aggregates. Sieve stacks are placed against a vertical set of drive rollers and the cabinet is tilted back for operation. No clamping is required. Sieves rotate as multiple hammers tap against them to promote particle passage. Enclosed cabinets isolate moving parts for safety to control dust and noise levels. We offer a variety of Rotary Sifters with Tapping, ranging from traditional to Gilson-enhanced models.
