The YA Series Vibrating Screen mainly consists of screen box, screen net, vibrator, damping spring device, chassis and other components. The side plates are made of high-quality steel plates. They are connected with the beam and the exciter base by high-strength bolts or ring groove rivets. The cylinder-type eccentric shaft exciter and the eccentric block are used to adjust the amplitude. The vibrator is installed on a side plate of the screen box. Driven by the motor, the eccentric block of the vibrator would rotate at a high speed under the motivation of triangular belt. High-speed rotation further exerts strong centrifugal inertia force to stimulate the screen box move in a circular motion within specific amplitude. During operation, materials on the inclined screen surface are subjected to the impulse transmitted from the screen box so that they are put in a continuous throwing motion. When materials fall onto the screen surface, particles smaller than the screen size are sieved out to achieve classification.
