As the sifter starts, the radial centrifugal force is used to lift the two weight compartments up and together through accurately machined cams while compressing a spring. This controlled energy assures a smooth gyratory motion.

The drive, motor, and counter-weight assembly solidly connects to the two boxes. This lightweight, well proven design combines the three elements into one structure capable of withstanding the dynamic stresses required for years of continuous operation.
