On the basis of basic demand for circular vibrating screen with high production and low power loss,mathematical model with the pursuit of minimal power loss per productivity is established.

Pointing to the realtime monitoring and control of smallcircular vibration of the main vibration platform in graphite electrode abrading machine, the vibration of the main vibrationplatform in x, y axis is respectively detected by a eddy transducer with two probes.

With the advantages of circle vibrating screen and straight vibrating screen,elliptical vibrating screen attracts the attention of users in relevant fields.

In the optimal design on circular impact screen damping spring,traditional methods have a problem of causing complex computing process and local optimal design.
