Description
The screen machine is mainly composed of screen box, screen mesh, vibrator, damping spring device, bottom frame, motor and so on. Using cylindrical eccentric shaft exciter and deflector to adjust the amplitude, the vibrator is installed on the side plate of the screen box, and is driven by the motor through the triangle belt to rotate, generating centrifugal inertia force, forcing the screen box to vibrate. The vibrating screen side plate is made of high quality steel plate, and the side plate is connected with the beam and the base of the exciter by high strength bolts or ring groove rivets. The vibrator is installed on the side plate of the screen box, and is driven by the motor through the coupling to rotate, generating centrifugal inertia force, forcing the vibrating screen to vibrate and screen the sand and stone.

Performance Advantages
- 1、The exciting force can be adjusted, the flow can be changed and controlled at any time, and the adjustment is convenient and stable; Multi-layer screening, clear screening of each file specification, high screening efficiency.
- 2、In the structure, barrel type vibration exciter and partial block adjustment device are adopted, advanced rivets are connected to the assembled frame structure to improve the service life of the equipment, and the spring vibration damping device reduces the impact force on the foundation, and the probability of sudden failure is less in normal use
- 3、 Direct contact with the material of the parts are all made of stainless steel materials, easy to clean, the screen design is exquisite and durable, high efficiency, mesh is not blocked, no flying powder
- 4、 Using rubber vibration isolation spring, long service life, low noise, stable over resonance area. The body adopts a closed structure, which can effectively prevent dust pollution.
The number of screen layers of the circular vibrating screen has two layers, three layers, and four layers, generally a few layers out of several finished products and a return material, it generally follows the crushing equipment behind, can be screened and crushed first, can also be crushed and screened first, according to the specific production line process to determine, it can be fixed crusher with, can also be equipped with the main crusher mobile crusher
Working Principle
When the YZK series circular vibrating screen works, the eccentric block of the exciter is rotated at high speed by the motor through the triangle belt. The running eccentric block produces a great centrifugal force, which stimulates the circular motion of the screen box with a certain amplitude. The material on the screen is transmitted by the impulse of the screen box on the inclined screen surface and produces a continuous throwing motion. The particles smaller than the screen pass through the screen when the material meets the screen surface, so as to achieve classification.
