China supplier flour vibrating screen classifier
Product Application
High frequency vibrating screens are the most important screening machines primarily utilised 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.
Working as the vibrating screen classifier, it has the following features:
1. Exquisite and durable design with high efficency to screen and sieve any powder and granules.
2. Easy to replace the screen mesh, to operate, and to clean
3. No mesh-obstruction and power-floating, and the screening precision can reach 500 mesh /inch
4. Automatic material-discharge, continuously working
5. Small size, easy to move
6. Unique design of screen holder, and durable screen mesh which only needs 3-5 minutes to make the replacement.
7. Stainless steel and carbon steel is optional
8. Max six decks or layers of screen mesh are available.
1. By means of unbalance hammer mounted along the motor shaft, rotary vibrating screen convert the rotation of the motor into a 3-D movement, i.e. horizontal, vertical and inclined movement.
2. Then the 3-D movement is transferred to the vibration screen surface, which leads to an involutes movement of the materials on the screen surface.
3. Vibrating screen classifier 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 vibration screen surface. It has the feature of long trajectory of materials and high utilization rate of vibration screen surface.
