  The  vibrating screen  is a very important auxiliary equipment in the mine production, which will directly affect the normal operation of the production line if the vibrating screen fails. As a common type of vibrating screen, what are common problems of the circular vibrating screen (also known as the round vibrating screen) in the daily operation? And how can we solve them? This paper analyzes the causes of five common problems of circular vibrating screen and puts forward countermeasures. One. The shaft of circular vibrating screen breaks In general, the  circular vibrating screen  is mainly driven by an electric motor with an eccentric mass vibrator to produce vibration. In the vibrating process, the shaft is the key component to drive the vibration of the circular vibrating screen. Therefore, the break of the shaft is a common fault in practical use. Once the shaft failure occurs, the circular vibrating screen will immediately stop working, and its mainte...

As the main equipment used in the screening operation,  screening equipment  is used for screening, dewatering and thickening in the whole mineral processing. The screening equipment can not only screen the qualified material before crushing, avoiding the over-crushing phenomenon and reducing the energy consumption of the crusher, but also check if the material is at suitable granule or not, and screen the material into several classifications for separation, increasing the processing efficiency. At present, there are three types of vibrating screen widely used in the mineral processing, include circular vibrating screen, auto centering vibrating screen and linear vibrating screen. 1.   Circular Vibrating Screen Circular vibrating screen  is suitable for the material classifying of the mineral, construction material, electricity,chemical industry and other departments. It can be used to dewatering, de-sliming, and de-medium. The circular vibrating screen uses ...

In the actual mineral processing plant, the mine owners found that the vibrating screen cannot reach the expected processing capacity and the screening efficiency of the vibrating screen is low. In fact, the screening efficiency of the  vibrating screen  will directly affect the quality and investment cost. When it comes to the screening efficiency of vibrating screen, many factors will make a difference, such as material properties, equipment structure and various performance parameters. Irrespective of the hard factors of material properties and equipment structure, we mainly  analyze the influence of various parameter indexes on the efficiency of the vibrating screen,  including amplitude, vibration frequency,vibration direction angle, screen tilt angle and the throwing angle, these are the reference for the vibrating screen operation. 1. Amplitude of the Vibrating Screen Generally, the larger the vibrating screen model, the greater the vibrating screen am...

There are many classification methods for  screening equipment , which can be classified according to the motion track and transmission mode, or classified according to their use. According to its structure, working principle and application, it can be roughly divided into : Screening Equipment Types Motion Track Maximum Feed Size/mm Application Static grizzly Static 1000 Pre-screening Cylinder screen The cylinder rotates in a certain direction. 300 Ore classification, desliming Roll screen The screen roll rotates in a certain direction. 20 Pre-screening, bulk mineral screening, de-intermediation Shaker screen Approximate straight line 50 Classification, dehydration, desliming Round vibrating screen Circle, ellipse 400 Classification Linear vibrating screen Straight line,   Quasi line 300 Classification, dehydration, de-intermediation Resonant screen Straight line 300 Classification, dehydration, de-in...

As a common equipment used in ore dressing plant,   vibrating screen   mainly uses vibrator to produce reciprocating vibration, push the movement of the screen mesh then complete the screening operation. According to the moving trajectory, vibrating screen can be divided into   linear vibrating screen ,   round vibrating screen   and custom vibrating screen. 1. Application of Vibrating Screen The flow of ore dressing production line is divided into pre-beneficiation, separation and tailing treatment, in which the vibrating screen is mainly responsible for material screening after crushing, and sending the qualified materials to the next grinding operation. That disqualified material is returned to the crusher again. 2. Effects of Poor Maintainance As the above mentioned, the foundation of vibrating screen in the ore dressing process is equivalent to the base of house. High buildings cannot rise from the ground without the solid base. So, if you want to ...

In the actual beneficiation plant, many mine owners have encountered the problem that the   vibrating screen   fail to reach the predetermined processing capacity and the screening efficiency of the vibrating screen is low. As an important vibrating screen, the screening efficiency of the vibrating screen will directly affect the quality and investment cost of the final product. When it comes to the screening efficiency of vibrating screen, many factors will make a difference, such as material properties, equipment structure and various performance parameters. Irrespective of the hard factors of material properties and equipment structure, we mainly analyze the influence of various parameter indexes on the efficiency of the vibrating screen, including amplitude, vibration frequency, vibration direction angle, screen tilt angle and the throwing angle, these are the reference for the vibrating screen operation. 1. Amplitude of the Vibrating Screen Generally, the larger ...

It has become a consensus that the working noise is relatively large in the mineral processing plant, which not only affects the lives of people in the surrounding areas, but also causes physical and mental damage to the operators. With the continuous development of the mineral processing industry, the technology of noise reduction is more and more advanced. Today, Xinhai illustrates how to reduce noise taking   vibrating screen   the as an example. Generally, the vibrating screen is featured with the high noise level and complex sound source. So how to effectively reduce the noise of the vibrating screen? Xinhai technical expert summarizes several methods of noise reduction as follows. First, whether the loose parts of the equipment cause noise. Therefore, the first method of noise reduction is to tighten all the parts of the vibrating screen, especially the screen plate that should be replaced frequently. Next, paste with   rubber  board on the side of scr...
