First, the structure and working principle of pulverized coal vibrating screen

Pulverized coal vibrating screen is mainly composed of vibrating motor, screen body, primary damping spring, secondary damping spring and bottom plate. The pulverized coal vibrating screen rotates synchronously and reversely through two vibrating motors, and the screen body is driven to make periodic reciprocating motion by exciting force. The material on the screen surface will make a linear parabolic motion on the screen surface, and the pulverized coal layer will be quickly broken and form the undersize through the screen, while the remaining sundries will be left on the screen and cleaned manually.

Second, the installation and debugging of pulverized coal vibrating screen

1, first of all, check whether the site foundation for installing pulverized coal vibrating screen is consistent with the screen installation drawing.

2. The installation of pulverized coal vibrating screen has a strict sequence, that is, from bottom to top, first fix the bottom plate, then install other secondary vibrating springs, secondary damping springs, primary damping springs, then the screen body, and finally the vibrating motor.

3. Adjust the positions of all kinds of rubber springs and bottom plates installed in the previous step, and try to keep them vertical to avoid being skewed. It is best to weld the bottom plate and the foundation plate together.

4. Finally, it should be noted that the two motors of the pulverized coal vibrating screen turn in opposite directions.

Third, the use and maintenance of pulverized coal vibrating screen

1. It is best to check whether the bolts on the pulverized coal vibrating screen are loose from time to time. If it is loose, tighten it as soon as possible.

2. The vibration motor of pulverized coal vibrating screen should be overhauled once a year, just like physical examination, especially to check the wear of bearings and add lubricating oil in time.
