  • Mechanical screening

    High frequency vibrating equipment is a shaker whose frame is fixed and the drive vibrates only the screen cloth. High frequency vibration equipment is for particles that are in this particle size range of an 1/8 in (3 mm) down to a +150 mesh. These shakers usually make a secondary cut for further processing or make a finished product cut.
