Flour sieve machine are the most important screening machines primarily utilized in the mineral processing industry. They are used to separate feeds containing solid and crushed ores down to approximately 200um in size, and are applicable to both perfectly wetted and dried feed. The frequency of the screen is mainly controlled by an electromagnetic vibrator which is mounted above and directly connected to the screening surface. Its high frequency characteristics differentiates it from a normal vibrating screen. The high frequency vibrating screens usually operates at an inclined angle, traditionally varying between 0 to 25 degrees and can go up to a maximum of 45 degrees. Besides, it should operate at a low stroke and has a frequency ranging from 1500 - 7200 RPM.

 By means of  unbalance hammer mounted along the motor shaft, convert the rotation of the motor into a 3-D movement, i.e. horizontal, vertical and inclined movement, and then the 3-D movement is transferred to the vibrating screen surface, which leads to an involutes movement of the materials on the screen surface. That’s why it is also called the Rotary Vibrating Screen.  Fine rotary vibrating screen for sugar powder and particle can handle the material into the Precision Screening or Probability screening by adjust the upper and lower ends of the phase angle of the hammer so as to change the movement trajectories of materials on the vibrating screen surface. It has the feature of long trajectory of materials and high utilization rate of  vibrating screen surface.
