The D450 digital is a vibrating shaker that is used to carry out sieve tests in conjunction with sieve stacks for particle sizing of various material samples. It is based on an electromagnetic drive, with special carbon fiber springs that are set at a calculated angle to provide a horizontal twist, as well as a vertical movement to carry out efficient sieve tests. The D450 has a remote control unit that houses a digital controller to vary the vibration, process time, and intermittent settings. The intermittent time operates within the process time so that the vibration is turned on and off during the total sieving time. The intermittent timer is controlled by an override switch to enable the shaker to operate in the continuous or intermittent mode.
