What is a Vibrating Screen? Vibrating Screens are machines used to separate aggregates by particle size by means of an exciting force applied to the machine. The vibration lifts the material, causing it to stratify, allowing the smaller material to move from the top of the depth of material to the bottom of the material, thus exposing them to ...

The screening machine is driven directly through a cardan shaft. The vibrating element is a through shaft, mounted in the two screen webs and fitted with unbalance segments. All clamping parts and screen mats are easily changed. The design features high acceleration on the deck surface which permits handling of difficult-to-screen materials.

The speed of the screen can be assessed with a contact tachometer or strobe light. The acceleration of a screen is measured with the following equation: (Screen Speed in RPM)2 X (Screen Throw in inches) = G'sRMS 100,000 General Screen Acceleration Standards Application Nominal Aperture Size (mm) of Screening Elements Stroke (mm)

(a) or stroke (2a) affects the vibration G-force. Hence, G-force of a vibrating screen can be altered/changed by changing speed and/or changing amplitude of the vibrating screen. Vibration frequency (f) can be changed by changing drive's V-belt pulleys or inverter parameters.

Large vibrating screens represent a unique challenge for Manufacturers, Plant Designers, and Plant Operators. The inherent mode of operation for vibrating ... The term is also referred to as "stroke". For a straight line motion screen the "throw" is the distance between the extremities of motion. For a circular motion screen, the ...
