Introduction
YK series circular vibrating sifter 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, under-frame and motor.
Working Principle
When circular vibrating screen on operation, first the materials will feed on the screen mesh, and the materials will separated uniformly on screen mesh plates.
The rolling bearing of the screen will stressed by highly mostly shock-type loads.
And more, the screen bearing ,while rotating about their own axis, going a way of circular ,elliptical or linear vibrating motion .This results in high radial accelerations which additionally stress the bearings , and especially the cages considerably.
The operating speeds are usually in a very high condition.
As a result, the bearing temperatures are up to 20 to 30 degrees Kelvin higher than in normal applications.
In addition, considerable misalignment between the bearing locations and considerable shaft deflections have to be accommodated.
Features
Ring groove rivet connections, advanced structure, strong and durable.
To connect sieve and the sieve beams by using high strength bolts, simple structure and convenient maintenance.
To use eccentric block as the excitation power, strong power, low power consumption and noise.
Small amplitude, high frequency, large angle structure, high screen efficiency, and high processing capacity.
Vibrator uses a large clearance bearings, thin oil lubrication, low noise, long service life. universal parts and easy maintenance.
Application
Circular Vibrating sifter is widely used in mining, power stations, water conservancy projects, building industry, light and chemical industry, for coal dressing as well as in metallurgy. Generally, these models are built to specifically classify large, middle and small materials efficiently.
