Rotary Centrifugal Sifter (Twin Shaft)
Dual-drive centrifugal screener machine for high-capacity scalping and sifting of bulk solid materials
The twin-shaft rotary centrifugal sifter features a dual-motor system, independently controlling the feed screw and sifting chamber. Material is conveyed by the screw into the rotating chamber, where high-speed blades perform efficient sieving and filtration. Oversized particles are automatically discharged through the coarse outlet for further processing. Independent control of feed rate and sifting speed allows precise operation and significantly improves screening efficiency.
