General SCREEN Information
screen sheaves are specially machined so that, when in operation, there is a point of zero sheave run out. In other words, if a line were drawn from the center of the driven sheave through the center of the motor sheave, there would be no movement towards or away from the motor sheave where that line crosses the outer diameter of the screen sheave.

Vibrating Screen Capacity Calculations – MEKA
The material velocity of a circular vibrating screen can be calculated from the corrected theoretical speed of the product formula written below. Example: Determine the material velocity of a screen vibrated at 900 RPM with a 12 mm stroke and 20° degree inclination angle. To calculate the bed depth of the material, the following formula is used.

Capacity Calculation for Vibrating Grizzly Feeder
Feed Capacity. The capacity of vibrating grizzly feeders is calculated according to the following formula: Q=3600 x f1 x f2 x f3 x L x H x V. where, Q=Feed Capacity in (m3/hr) To obtain capacity in Tons per Hour, multiply by bulk density of the material. Qt = Q x bd. bd = 1.6 Tons/m3 for sand and crushed stone. f1 is the Size Factor.

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. The lower weight acts to tilt the machine, causing vibration in the vertical and tangential planes.
