Direct Eccentric Drive Vibrating Screen
Drives
To drive a circular vibrating screen, an exciter cell is flanged to both of the side panels. The two exciter cells are joined together by an intermediate drive shaft. Both vibrating screen exciter cells are driven by a stationary standard electric motor via a drive shaft.

Vibrating Screen | Mine Screening Equipment
【Description】 Vibrating screen is a kind of mine classifiion machine for ore, mine, sand, gravel, coal, slurry, etc. which consists of a screen and a vibrator. Generally below 50 mesh for the coarse screen, 80 mesh for the fine screen. The vibrator is an eccentric wheel that rotates under the drive of the motor, making the sieve frame vibrate.

Types of exciter for vibrating screen
· The drum vibration exciter is composed of two long shafts which cross the screen box, and the eccentric mass is distributed on the long shaft. Compared with the box type vibration exciter, the drum type vibration exciter is directly installed on the side wall of the screen box, with low installation height and no need for large Ibeam support.

Synchronization of Two Eccentric Rotors Driven by One ...
· The eccentric rotors drive the vibrating body to perform periodic forced vibration. On the one hand, the rotations of the eccentric rotors affect the motion law of the vibrating body. On the other hand, the translational and rotational motions of the vibrating body act as an implied motion, which in turn acts on the eccentric rotors, thereby causing a change in the .
