Screen Separator
G.A.S Engineers presents Screen Separators, designed to efficiently grade, screen, and separate materials of varying sizes and properties.
We manufacture and supply screen separators, a unique particle size gradable separator designed for greater capacity per meter square of screening area & size material discharge with relatively much fewer percentage fines than other screening machines.
Working Principle
The top weight on the motor shaft rotates in a plane close to the center of the mass of assembly. Rotation of the top eccentric weight creates vibration in the horizontal plane that causes the material to move across the screen cloth to the periphery. Increasing the top eccentric mass increases the horizontal throw, causing oversized material to discharge at a faster rate.
The bottom eccentric weight rotates below the center of mass, creating tilt on the screen, and giving vibration in vertical & tangential planes. Increasing the vertical component of motion, which promotes turnover of material on the screen surface helps the maximum quantity of under-size material to pass through the screen. The vertical motion minimizes the blinding of the screen by “near size” particles.
The tangential component of motion is controlled by the angle of lead given to bottom weights in relation to top weight. Variations in lead angle controlled the spiral pattern of material travel over the screen cloth can be set by the operator for maximum throughout & screening efficiency for any screenable product be it wet or dry, coarse or fine, heavy or light, hot or cold. Typical material passes rapidly through the screen during its travel to the periphery. The oversized material gets continuously discharged through a tangential outlet.
Standard sizes are available in 24” 36” and 48” diameter custom sizes can also be made on request.
