The model MOB-DD-SS dual-drive CENTRI-SIFTER centrifugal sifter from Kason Corp. allows independent speed control of the feed screw and helical paddle assembly. This allows each to be adjusted separately according to characteristics of individual materials for maximizing feed control into the sifter and for optimum efficiency and capacity.
The speed of the variable feed screw can be entered remotely or by an operator at the control panel. Material can be fed into the horizontal screen cylinder consistently at the desired controlled rate without the need for a separate feeding device, as required for repeatable sifting performance.
Rotation speed of the helical paddles, which never touch the screen, can also be adjusted to accelerate material against and through apertures in the screen cylinder at speeds sufficient to break down agglomerates and achieve desired throughput.
