There will be many problems in the process of installation, debugging, or use of the circular vibrating screen. Polarization and hanging foot vibration are some of the problems. If such problems are not solved, it will cause very big harm, such as the equipment that cannot be used, the screen body, and the screen. Break etc. Before leaving the factory, the circular vibrating screen must be debugged and then shipped to the customer. This is the guarantee of quality and is responsible to the customer.
1. The installation site of the circular vibrating screen is uneven
Due to the influence of the site environment, the circular vibrating screen may be difficult to place on the horizontal surface during testing and installation. This will cause uneven force on the vibrating screen, inconsistent spring compression, and small deviations in the exciter or vibration motor. Therefore, we need a horizontal surveyor to help us place the vibrating screen horizontally during installation. If the site is uneven, the thickness of the base needs to be increased or decreased on site.
2. The eccentric block is not consistent
The eccentric block of the vibrator determines the amplitude of the vibrating screen, which is the key to the normal use of the vibrating screen. Pay attention to the size and weight of the eccentric block during production, and ensure that all eccentric blocks are consistent. After the installation is completed, first measure whether the eccentric block of the vibrating screen is on the same level or whether all of it sags naturally.
It can be measured without the exciter casing. When the casing has been installed, the internal eccentric mass cannot be measured. Here is a little trick. Test run for some time, wait for the oil temperature to rise, loosen the exciter fixing screws, and the exciter will be eccentric. The blocks will sag naturally so that all eccentric blocks will naturally go down vertically.
3. The bolts of the vibration exciter are loose and severely worn
During the use of the circular vibrating screen, the bolts will be loosened due to long-term vibration, and the eccentric block will also wear out, which will cause the vibration of the vibrating screen to be unstable for a long time. Therefore, we should frequently tighten the bolts in daily maintenance, and measure the eccentric block to be generous. When the thickness of the eccentric block is different, it should be replaced in time.
These points are the reasons and solutions for the polarization or hanging foot vibration of the more common vibrating screens in use. I hope it will be helpful for you to use the circular vibrating screen!
