In this post we39re going to talk about 3 common problems of vibrating screen and how to solve them.
In production, because vibrating screen working environment is relatively complex, continuous work for a long time and bear heavy load, vibrating screen inevitably damaged or even failure. In order to ensure the normal screening operation of the processing plant, we need to carry out daily maintenance and overhaul of the vibrating screen, and take emergency measures in case of failure. The following is an introduction to some of the vibrating screen in the operation of common problems and solutions.
Solution Proper thickening of the screen plate is the most effective way to solve the screen plate is too thin, or for the exciter near the individual side plate to increase the attachment plate, in order to enhance the rigidity of the whole screen body, so that the screen frame is not easy to tremble and fracture. In addition, it is necessary to regularly check the wear of the damping spring and the eccentric wheel of the exciter to prevent spring failure and mass deviation.
The quality of vibrating screen directly determines the screening quality and screening efficiency. The reasons for the high screen breakage rate are mainly divided into the following 1. When the screen technology is poor, the two layers of screen can not be closely fit, resulting in cuttings can not be discharged. 2. Wrong steering of vibration motor. 3. Clay deposits. The vibration amplitude of soil pile is too small to overcome the clay39s cohesive force effectively, which causes the clay to accumulate quickly on the screen and damage the screen.
Solution 1. The quality of the screen should be strictly checked. 2. The operator can remove the protective cover of the vibrator and check the rotation direction of the eccentric block. Under normal circumstances, eccentric blocks are rotated laterally. 3. Rinse the screen and dirt with spraying water to reduce the stickiness of dirt.
Screen efficiency affected by different factors such as screen deck inclination, mesh size of screen, Amplitude of vibration, feed rate of material etc. In this study we considered effect of deck slope inclination on screening efficiency of vibration screen.

The rounder the rock and the greater the ratio of rock size to opening the faster the rock moves from the feed end of the screen to the discharge end the faster the rock is moving the less likely it is to pass through an opening the flatter the incline angle the easier it is for the rock to pass through an opening.
A vibrating mechanism attached to the middle of the screen imparts rapid vibrations of small amplitude to its surface making the ore which enters at the top pass down it in an even mobile stream the springloaded bolts which can be seen in section in fig 7 move with a hinge action allowing unrestricted movement of the entire screening surface without transmitting the vibrations to the frame.
