Vibrating screen - SKF

The bearing centre should be aligned with the frame centre of the vibrating screen . The housing wall thickness should be greater than 40% of the bearing width. Design the housing to be as symmetrical as possible, so it has the same thickness on both sides of the vibrating screen frame, in order to avoid housing deformation .

» Fault detection for mining and mineral processing equipment

Sep 16, 2001· In August 2000, a fault detection system was installed on a vibrating screen at a major aggregates plant in the United States. During installation, it was noted that the drive side bearing had a slightly higher vibration level than the vibration level in the opposite bearing. This was likely due to a slight mechanical looseness.

Noise Causes and Solutions of Vibrating Screen

The vibrating screen works by relying on the centrifugal force of the eccentric block to generate the vibration force. If the eccentric force deforms the eccentric shaft to produce a bend, the relative deflection of the inner and outer bases of the bearing will occur, and the trajectory of the rolling body will change, and thus increase.

Dillion Screen | Features - Vibrating Screens

The entire weight of the screen and feed load is suspended from four spring-mounted rods. The springs absorb any any shock load, so it is not transmitted to the bearings, unlike screens where the bearings carry the load. Vibration is confined to the screen body, reducing transmission to the supporting framework or to the building.
