Analysis of the reasons for the bad effect of vibrating screening
Mastering some common fault diagnosis and troubleshooting solutions for vibrating screens (vibration screens) is very necessary in production practice. But the same fault may be caused by a different cause. Today, our company analyzes and summarizes the reasons for the poor screening effect of common vibrating screens (vibrating screens), and summarizes them as follows: 1. For linear vibrating screens and high-frequency vibrating screens, the reason for poor screening results may be related to the direction of movement of the eccentric block of the equipment, because two sets of eccentric blocks of the same mass are required to perform self-synchronous reverse rotation, resulting in a single instant at each instant. In the direction of vibration, it is fixed with an angle of excitation force in the horizontal direction to make the screen box reciprocating linear motion. If they are not in the same phase, the direction of the exciting force does not overlap with the direction of vibration, so that the effect of efficient screening is not achieved. 2. For the circular vibrating screen, the most common reason for the poor screening effect is that the inclination angle of the screen surface is not enough, so it is necessary to raise the rear support seat. In practical applications, the inclination angle of the screen surface is suitable at 20°. Generally, the inclination angle of the circular vibrating screen is between 16 and 20°. If the inclination angle is less than 16°, the material on the screen may not be smooth or material. The phenomenon of scrolling up.
