  Vibrating Sieve Short Introduction

The main types of vibration sieve:

The product features and advantages: high efficiency, light weight, full range of diversified,multi-level, to meet the different needs of.

Advantages of vibration sieve

 Is mainly composed of a screen box, a vibration exciter, suspension (or supporting)deviceselectric motors etc.. Electric

 Through the triangle belt drive spindle rotation, vibration exciter, due to vibration exciterunbalanced centrifugal inertia force of heavy objects, so that was vibrating screen box.Change the exciter eccentric weight, get a different amplitude.

 The main advantages of vibration sieve:

 1, due to the strong vibration sieve boxes, reducing the material hole blocking phenomenon,the sieve has a high screening efficiency and productivity.

 2, has the advantages of simple structure, convenient disassembly and replacement ofscreen surface.

 3, screening materials consumed per ton less electricity.

 The mechanical structure

 Box, supporting or hanging device, transmission device and other components of generalscreen consists of a vibrator, vibrating screen.

 Single shaft vibrating screen vibrator and vibrating screen, press the eccentric weightallocation way to distinguish between two general

 Type. Eccentric weight configuration modes to block eccentric type is better.

 The screen box

 The composition of the screen box is composed of a screen frame, the screen surface andpressing device. Sieve box is composed of side plate and beams. Sieve box must have sufficient rigidity.

 Supporting device

 Supporting device of vibrating screen hanging type and seat type two. Seat type installation is simple, and the installation height is low, the general should be preferred. Supporting deviceof vibration sieve is mainly composed of an elastic component, commonly used in a spiral spring, plate spring and a rubber spring.

 Transmission device

 Vibration sieve usually adopts the triangle belt transmission device, shaker structure simple,can choose the vibrator speed, but the running belt is easy to slip, may cause the clogging of screen. Vibrating screen is also used for direct drive coupling. The coupling can maintainstable revolution of the vibrator, and the service life is long, but the speed adjustment difficulties vibrator.

 Working principle

 The materials on the screen surface to move towards the discharge end to a certain speed,at the same time the screening material. Shaker compared with the above several sieve, its productivity and the screening efficiency is relatively high. The drawback is that power balance. General dressing plant rarely use it, and be more reasonable structure to replace the vibration sieve.

 Working characteristics

 It uses eccentric block as an exciting force, strong exciting force.

 II, sieve and sieve box beams with high strength bolts, simple structure, convenient repair;

 Vibration sieve

 Vibration sieve

 The tire coupling, flexible connection, stable operation;

 Fourthly, the small amplitude, high frequency, large inclination structure, so this machine is of high efficiency, long service life, the largest processing, low power consumption, low noise.

 According to the structure and working principle of screening machinery following categories:

 1, roller screen working face is composed of a horizontal array of a rolling shaft..

 2, roller screen working face is composed of a horizontal array of a rolling shaft. Fixed screen.Fixed screen working part is fixed, by material along the work surface slides and the materialscreening. The fixed sieve is a more applied in beneficiation plant, commonly used forcrushing or crushing the prescreening before. It has the advantages of simple structure,convenient manufacture. No power consumption, can be directly put into ore unloading sieve.The main drawback is the low productivity, low screening efficiency, usually only 50 - 60%.

 3, the plane motion of the body swing or vibration sieve is a plane. According to the planemotion trajectory and divided into linear motion, circular motion, elliptical motion and complex motion. Shaking sieve and vibration sieve belongs to this category.

 The scope of application

 The scope of application of the vibration sieve is very extensive, involving almost every aspect of life need to use various types of vibration sieve in the processing andmanufacturing.

 Vibrating screen is mainly used in mines, coal, smelting, building materials, refractory materials, light industry, chemical industry, medicine, food and other industries.

 Vibration sieve in mineral processing plant was used most, according to the transmission mechanism is different, can be divided into the following several kinds: eccentric vibrating screen, vibrating screen, self centering vibrating screen, resonance screen.
