Benefits Brought by Improvement of Circular Vibrating Screen

1/7/2013 5:46:38 PM

The circular vibrating screen is a new kind of high efficiency screening equipment with a number of layers and its trajectory appears the circular motion. The circular vibrating screen adopts cylinder eccentric shaft vibration exciter and partial block to adjust the amplitude and it has many screening specifications. It is specifically designed for the screening of the stones in the quarry, it is also available for the product grading of the industry of mining, coal preparation, mineral processing, building materials, and electricity and chemical departments.

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. 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; (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 improving the service life of the screen. Under the same conditions, the service life of the screen can be improved at least five times after the improvement, and the screening efficiency is increased by 20% and the economic benefits have been significantly improved. Moreover, it also reduces the labor intensity and realizes the energy savings.
