example will assign operating parameters typical of its category. A The Gyratory Screen: 285 rpm, 2-1/2" horizontal circle dia. B. The Shaking Screen: 475 rpm, 1" stroke, zero pitch, 6 deg. slope. C. The Inclined Vibrating Screen: 1200 rpm, 1/4" vertical circle dia. D. The Horizontal Vibrating Screen: 840 rpm, 1/2" stroke at 45°.
Generally, power is transmitted from the drive motor to the assembly via a V-belt transmission. The speed of the screen (frequency) can be adjusted by changing the ratio of the V-belt sheaves. The eccentrically-bored screen sheave offsets the stroke so that drive centers do not change during operation.
Principle and Operation of the Vibrating Screen. In the case of a vibrating screen, the vibrations are given to the screen to effect the separation of solid particles into two size fractions. Vibrations given keep the solid particles moving. Proper selected frequency and amplitude keep the capacity constant.
