High frequency vibrating screen is a screening equipment in pulp and paper industry. It is mainly used for the roughing and purification of pulp and the treatment of pressure screen tail pulp. The equipment uses spring and tape as shock absorber. It has the advantages of simple structure, convenient maintenance, low production cost, small floor area and high production efficiency.

3. Structure and working principle
The machine is mainly composed of screen frame, vibration system, vibration damping device, slurry tank and so on. The vibration of the screen frame is realized by two eccentric wheels mounted on the main shaft. The spindle is connected with the motor by a flexible coupling and the screen frame is supported by a spring. It has the advantages of simple structure and good practical performance. This machine is divided into left and right hand operated machines, and users can choose them according to their needs.
The slurry flows into the screen frame from the pulp box, and the coarse impurities in the pulp are screened out through the high frequency vibration of the screen frame. The fine pulp is discharged through the sieve plate and discharged from the pulp outlet. The coarse impurity is discharged from the end of the screen frame.
