The purpose of screening is to separate a flow of aggregate particles into uniform sizes. This is accomplished by using Vibrating Screens. 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 vibrating action of the screening machine separates the particles, discharging the smaller unwanted materials through "holes" of specified shape and diameter in the screen and retaining the larger particles for further processing. The screens are round or rectangular and are attached to a frame within an assembly, called a screen deck.
A linear vibrating screen is a particularly effective solution for separating product as the vibration throws material forward along a length – allowing the smaller pieces more opportunity to drop through the screening deck, whilst also maintaining production efficiency by feeding the material onto the next process.
