Purposes; 
 Mine is a single-axis shaker for circular movement of the shaker. Available in black, non-ferrous and non-metallic mines, assisted or independent screening operations for medium-size classification purposes. The screen has a simple structure, stable and dynamic change, working and reliable. 
 Works; 
 Department of Mining of the original single-axis shaker screen box, vibrators, springs and other components. Screen box with a welded structure, solid and reliable, except in the vibrator on the middle part of the spindle system of the eccentric, the two ends of the spindle has an adjustable eccentric weight eccentricity, or both ends of the shaft is also re-installed the system out eccentric adjustable eccentric weight of the oval wheel. Motor with a drive through the triangular glass vibrators, to a certain speed rotating shaft, so the quality of the eccentric shaft and eccentric inertial force generated in the force, the screen box for approximate circular motion, the spring is used in supporting the screen box, but also sieve in operation to reduce the pass-based power. Seat equipped with spring damping device horizontally. Limit sieve sieve of lateral swing and reduce the amplitude of resonance.
