Optimizing Vibratory Screen Separator Performance
In vibratory separators, lead angle is defined as the CCW angle between the top and bottom weight when viewed from above. When the weights are vertically aligned, there is a zero degree lead angle. When the bottom weight is 120 degrees CCW from the top weight, and the motor is spinning CCW, the bottom weight leads the top weight.
SWECO Round Vibratory Separation Equipment
Basically, the SWECO Separator is a vibratory screening device that vibrates about its center of mass. Vibration is accomplished by eccentric weights on the upper and lower ends of the motion-generator shaft. Rotation of the top weight creates vibration in the horizontal plane, which causes material to move across the screen cloth to the periphery.
Vibrating Screen - Vibrating Screen Machine Manufacturer
The bottom eccentric weights rotate below the center of the vibrating mass creating tilt on the screens giving vibration in vertical and tangential planes.
