Best Solutions For Wet Or Dry Screening BMPE Screen Separator

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

Working Principle

Gyratory screen separator In India

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 turnover 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 controls 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 throughput & screening efficiency for any screenable 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 oversize material gets continuously discharged through a tangential outlet.
