SCREEN SEPARATORS
STAR TRACE Screen Separator is a unique particle size gradeable separator
designed for greater capacity per metre square of screening area &
over size material discharge with relatively much less percentage fines
than other screening machines.

WORKING PRINICPLE
The top weight on the motor shaft rotates in a plane close to the centre
of the mass of assembly. Rotation of the top eccentric weight creates
vibration in the horizontal plane which causes material to move across
the screen cloth to periphery. Increasing the top eccentric mass, increases
the horizontal throw, causing oversize material to discharge at a faster
rate. The bottom eccentric weight rotates below the centre of mass, creating
tilt on the screen, giving vibration in vertical & tangential planes.
Increasing the vertical component of motion, which promotes turn over
of material on the screen surface helping maximum quantity of undersize
material to pass through the screen. The vertical motion also minimizes
blinding of screen by “near size” particles. The tangential component
of motion is controlled by the angle of lead given to bottom weights with
relation to top weight. Variation in lead angle controlled the spiral
pattern of material travel over the screen cloth. Speed &flow pattern
of material travel over the screen cloth can be set by the operator for
maximum throughout & screening efficiency for any screen able product....
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 over size material get continuously discharged through a tangential
outlet.
