Structural Vibration as a Noise Source on Vibrating Screens

deflection shape (ODS) analysis was used to examine the screen behavior under actual operating conditions. This information is helpful in determining how to modify the screen body to reduce the noise radiated by the screen below 1 kHz. The analysis showed modal vibration patterns on the sides and feed box were the main contributors to noise.

The distance between the bearings is 3 metres, and the vibrating screen structure is made of welded and bolted steel parts. Shaft deflection and misalignment of supports under load require bearings that can compensate for misalignment. Spherical roller bearings are selected for this new vibrating screen , which is the typical solution. They can ...

Dynamic design theory and application of large vibrating ...

Sep 01, 2009  The enlargement of structure of vibrating screen will lead to the increase of vibration mass and exciting force. Dynamic load on the vibrating screen is also increased which will lead to a greater deformation, tear of the side plate, fracture of the crossbeam, and thus affects the service life of the vibrating screen seriously [1-3] .

Eriez - Vibratory Screeners

Eriez High Deflection Screeners have the advantages of an electromagnetic design with the added benefit of high amplitude. Operating at a fixed 1800 vibrations per minute and approximately 1875 amplitude, the HD designs offer the nearly maintenance-free operation of our electromagnetic design with high amplitude, similar to a mechanical screener.

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.

SCREEN CAPACITY CALCULATION - VIBFEM

VIBRATING SCREEN – CAPACITY CALCULATIONS Throughput per square foot of screen area is the name of the screen game, and no design engineer wants to be considered short in the area of capacity and efficiency. It behooves the buyer/operator to examine and evaluate the data available before committing to any screen type or system.

Mounting Bases and Vibration Isolation

Vibration isolation is the process of isolating an object, such as a piece of equipment, from the source of vibrations.. Vibration is undesirable in many domains, primarily engineered systems and habitable spaces, and methods have been developed to prevent the transfer of vibration to such systems.
