Abstract
A batch-type centrifugal system utilizes a gimbal-like suspension at the end of a rotating shaft distal an attached bowl at the other end of the shaft. The shaft rotates within an elongated bearing which is supported proximal the bowl by a support which is selectively variable in resiliency. This variation in resiliency changes the natural radial frequency of the system whereby operation of the system at rotational speeds which correspond to the natural radial frequency may be minimized, thereby effecting smooth loading, drying, and unloading operations.
