Circular Vibrating Screen

Circular Vibrating Screen
    YK series circular vibrating screen is a kind of screening equipment with multiple layers of screen and circular vibrating track. The flow distance of raw materials on the screens is long, the screening grades are multiple, and the screening effect is excellent. It adopts the adjustable drum exciter and eccentric shaft with counterweight wheels. This vibrating screen is of these advantages of reliable structure, powerful exciting force, high screening efficiency, low noise, long service life, convenient maintenance, safety, etc. It is widely used in the gravel plants, mining, construction materials, communication, energy resource, chemical and other industries.

Working Principle

    YK series circular vibrating screen uses the motor driving two pairs of exciters on the both sides of screen box through the couplings with rubber type element. The two pairs of exciters, connecting with the universal joint coupling in the middle, rotate synchronously under the unequal centrifugal force. Under the action of the exciters and the spring group, the screen box can be vibrated in full amplitude by the near circular track. Meanwhile, the raw materials on the screens are thrown under the action of the screen box vibrating. During the process of raw materials jumping and rolling forward, the materials smaller than the sieve mesh will fall down layer by layer until out of the screen box.

Feature

a) New structure, advanced technical parameters, large capacity and high screening efficiency.
b) Adopting the exciting motor as the exciting resource, using and maintenance easy.
c) The screen adopts the spring steel knitted mesh or punched hole plate, with long service life and hardly blocking.
d) Adopting the vibration isolation rubber spring, with long service life, low noise and passing the resonance area stably.

Technical Parameters

Operation and Maintenance

a) The vibrating screen should start up under the no-load condition. When the operating is stable, it is allowed to feed materials. It must stop feeding materials before shut down. Keep inspecting, if there are unmoral circumstances, the machine must be shut down, find out the reason and clean the troubles.
b) Before the test run, check whether the installation of spring bearings on both sides meets the requirements. Check the press amount of springs, and keep the height differences smaller than 5mm in the four directions of forward, backward, leftward, and rightward. Fasten all of fasteners and pour into appropriatelubricating grease. The no-load test run must jog test run firstly, and confirm that there are no abnormalities.
c) Make sure that the V-belts are in reasonable strength, with enough adjustment amount. Make sure that the grooves of the two belt wheels correspond to each other in their respective planes
d) The load test run can put into after the no-load run test qualified. The time of load test run time can be carried out according to the process test requirements
e) The exciters must be turned by hand before commissioning, confirm that rotating is flexible and no jam phenomenon.
