gyratory screen

[′jī·rə‚tȯr·ē ′skrēn]

(mechanical engineering)

Boxlike machine with a series of horizontal screens nested in a vertical stack with downward-decreasing mesh-opening sizes; near-circular motion causes undersized material to sift down through each screen in succession.

Literature

This resonator, which is externally mounted to the gyratory screen is powered by an auto tuned 200 watt x 36KHz generator.

Wet/dry ultrasonic sieves ideal for lab or small batch applications

Advantages claimed for it, in comparison with circular gyratory screens, include full travel of material from feed end to discharge end without any shortcutting of the screening path, and simple deck slope adjustment.
