Characteristics of Vibrating Screen --- an Efficient Screening Tool

Screening operation is an important part of mining. The vibrating screen, compiled of mainframe, eccentric bock, screen web, rub spring, electric motor, coupler and some more, is one of the most extensively used screening tools and it is designed for especially screening stone stock of quarry, and also for classifying products of such departments as coal separator, mineral processing, building materials, electricity and chemical industry, etc. It is advanced at home and abroad, and is well accepted by customers. Here is brief introduction of vibrating screens. Here different products by China manufacturers and suppliers for your choosing also:

Vibrating screens, such as linear vibrating screen, circular vibrating screen or elliptical vibrating screen, commonly work at fixed vibration intensity. They have multi-layers and are of high efficiency. And material on the screen surface moves by throwing, rolling or sliding motions.

Here’re working principles of vibrating screens. The electric motor makes the driver eccentric cause high speed revolving through triangle belt. The revolution eccentric has the very big centrifugal force, which stimulates sieves box to have circular motion with certain oscillation amplitude.

The materials on sieves receive the impulse which the sieves passing to produce continual throwing movement in the inclined screening surface. In the process of the material and the screening surface meeting, it makes the pellet which is smaller than the mesh pass sieves, thus realizes the graduation.

Its law of motion about vibrating screen is the circular or the ellipse line; the vibration source is the driver leading for the electric motor. The circular oscillation sieves is the single axle vinrator, the main axle fixed in sieves box makes fast revolving by the electrical machinery, the eccentric body installed on main axle makes rotation along with it, and causes the centrifugal force of inertia, which makes the sieve box that can have free vibration have the approximate circular trace’s vibration.

Vibrating screen has simple and dependable eccentric type system as well as high screening capacity and high durability. It is one of the unique and efficient screening equipment for the classification of bulk material. It’s optimized to different screening demands.
