the vibrating screen is a kind of sieving equipment of international advanced level, developed by our company on the basis of carrying on the advantages of traditional screens and absorbing the outstanding technology from abroad. vibratory screen moves round. it has multi-layers. the model of means the vibrating screen has two layers screens, and the modle of means the vibrating screen has three layers vibrating screen is of high efficiency. the eccentric shaft vibration exciter and partial block help to adjust amplitude. the material drop down the long line. vibrating screen are used to separate materials into various sizes for further processing. or for end use. depending on our need. the material is separated by passing it through a vibrating “screen box” which has a number of different sized screens, or meshes, which the material falls through like a sieve, the material falls onto attached conveyors which stock pile the end products. the end products can then be used in the building and construction industries.
compared with the traditional dillon, zenith, sweco, allgaier, wacker, cedar rapids vibrating screen, sbm bucket vibrating sieve screen is of low cost, easy maintenance, detailed handbook, easy adjustment etc.
the vibrating shaking screen’s application includes concrete, rock, crushed stone, quarry waste, ore mineral mining, construction, demolition debris, aggregate, dewatering industrial, sand and gravel etc.

used vibrating screen working principle
vibrating screen working principle: by the motor force and adjusting the amplitude of the eccentric shaft, vibrating screen moves quickly like a circle. materials in the sieve case can be saperated and screened from the sieve pore in this process.
vibrating screen moves round. it has multi-layers and is of high efficiency. the eccentric shaft vibration exciter and partial block help to adjust amplitude. the material drops down along the long line. in screen grading, the material is separated mechanically on screen plates. rolling bearings in vibrating screen are stressed by high, mostly shock-type loads. moreover, the bearings, while rotating about their own axis, perform a 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 of the vibrating screen are usually very high. as a result, the bearing temperatures are up to 20 to 30 degrees kelvin higher than in normal applications. in addition, considerable misalignments between the bearing locations and considerable shaft deflections have to be accommodated.
the screen plates can be divided into two types, mono-layer and multi-layer. all types of screen plates shall be in conformity with requirements of high efficiency separation, long life without blocking the hole bottom. the screen of this series is in pedestal assembly. the inclination of the screen face can be adjusted by changing the height of the spring base. the generator is installed on the left or right side of the screen frame. the materials shall be supplied on the right side along the movement direction unless otherwise specified.
used vibrating screen structure & features

used vibrating screen project case
mount owen coal mine, australia
mt owen is located in the upper hunter valley of new south wales. thiess contractors operates mount owen as a shovel-and-truck open pit, relying on hydraulic excavators for both overburden stripping and coal production.
a number of technical innovations have been incorporated into the design of the mine. the benefit of this is to minimise the creation of fine coal during crushing, while removing the need for a separate screening operation.
vibrating screen from zenith machinery is widely used for sieving and separating the crushed coal in the coal preparation plant.
