Structural features griddle trajectory classification and anti-vibration method

Griddle screen box because the trajectory is circular or oval but called circular vibrating screen. And because griddle only one axis, also known as single-axis shaker.
   Griddle griddle is divided into ordinary and self-centering griddle, the difference between them lies in the different coal crushing plant structure of the vibrator, the former center of the

pulley bearing center is located on the same line, when the griddle operation, pulley will immediately sieve Box shake together, thus causing repeated stretching of the belt is

leaving

Easy to damage, and coal production line require a smaller amplitude. Because of these shortcomings, the griddle has been rarely used in the production process. Self-centering griddle pulley center

is located between the center and the center of the eccentric bearing, and to the center line of the eccentric pulley blocks the body's synthesis and Vibration

Centroid, and therefore, when the griddle work, not with the pulley with vibration sieve box, the rotational movement produced thereby is also possible to employ a larger

amplitude in order to improve screening efficiency. Thus, self-centering griddle developed rapidly gained widespread application. Currently used in mine production

Griddle are generally self-centering griddle belongs to this type.

   Griddle in the activation and deactivation, since the resonance region, the amplitude of the screening machine speed will increase, causing severe overload spring to

shortened life expectancy, belts easily damaged, and it will affect plant construction safety. Damper device is used to eliminate the resonance phenomenon, Paul

Mine permit safe operation. When increasing the rotational speed of the vibrator to about twice the critical speed, the eccentric block pop work required to produce the

vibration force and amplitude.
