Description
Circular Vibrating Screen is a kind of new and highly effective vibrating screen that does circular vibrations and has multiple layers. Circular vibrating screen adopts cylinder postures eccentric block to produce strong exciting force. Its main body is connected by high strength screw bolts. A circular, elliptical vibration motion is created in order to sieve the materials efficiently. It is composed of screen box, screen mesh cloth, suspension (or support) device, underframe and motor.
Working principle
Circular vibrating screen separator uses eccentric block(YK type)/eccentric shaft(YA type) to produce strong exciting force, due to the unbalanced centrifugal force of inertia of the weights on the exciter, screen box vibrates, it can obtain different amplitudes by changing the exciter eccentric weight.
Application
Ore circular vibrating screen is available for smelting , quarry , coal preparation, ore dressing, energy, power, chemical industry,construction material.
Features
1.Simple structure, easy maintenance, high production efficiency
2.Using large clearance bearings and lubricated with thin oil, little noise and long service life
3.Sieve beam and screen box adopts high strength bolt connection, no welding processing
4.Small amplitude, high frequency, large dip angle structure to enable high screening efficiency and great handling capacity.
Advantage
A.Common features and performance of our Circular Vibrating Screen
1.High screening efficiency
2.Strong vibration force created
3.Adoption of punching sieve or steel made screening mesh in order to prevent blockage.
4.Screen body connected by using high strength screw bolts.
5.Adopts spring steel woven mesh or perforated sieve-plate, which is helps to prolong the service life and prevent blockage.
6.Rubber vibration spring is used to reduce noise pollution and provide smooth vibration operation.
B.Drive and Mounting of Circular Vibrating Screen
Drive is by electric motor and cardan shaft to the main drive shaft equipped with a single unbalance weight where required additional v-belt can be provided. The drive shaft is mounted on heavy duty roller bearing sets, lubricated with grease or oil. Like the linear vibratory screens, circular vibrating screens are mounted on reinforced rubber springs to prove the same benefits in performance and longer lifespan.
