Circular vibrating screen is the powder screening equipment with high precision. Its low noise, high efficiency, rapid replacement of the screen and the fully enclosed structure make it available for the screening and filtering of powder, mucus and other materials Diamond Mining Equipment . Circular vibrating screen is equipped with the vertical motor that is used as the excitation source, the eccentric hammers are mounted on the both ends of the motor, which makes the rotary motion of the motor turn into the three-dimensional movement of horizontal, vertical and inclined and then this movement is passed to the screen surface. Adjusting the phase angle of the upper and lower ends can change the trajectory of the material in the sieve surface. In addition, the circular vibrating screen is characterized by the following features: (1) it is easy to replace the screen, to operate and to clear up the machine vertical roller mill in cement industry ; (2) the mesh is not blocked, the dust is not easy to fly around; (3) the impurities and coarse material can be discharged automatically, it can realize the continuous operation.
Through the improvements of the sieve tensioning and the reasonable regulation of the phase angle of the hammer, the status quo of the frequent breakage of the screen has been completely changed, greatly reducing the blocking rate of the mesh and
