Screen Separator 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.
MAJOR USER INDUSTRIES
• Mineral processing Pharmaceutical
• Ceramic Animal Feed
• Food & Beverages Effluent & Waste
• Abrasive Industries water treatment.
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 under
size 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.
