# how to calculate the capacity of vibratory screen deck

#### 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.

#### SCREEN CAPACITY CALCULATION - VIBFEM

Association formula to determine screen capacity. The twelve factors used in the formula below are based in large part on the VSMA charts and formula. Formula: A = B * S * D * V * H * T * K * Y * P * O * W * F “A”, the calculated capacity per square foot of screen area in tons per hour. B = Basic capacity per square foot in tons per hour

#### Vibrating Screen Deck - Required Screening Area Formula

Applies when water is sprayed on the material as it moves down the screening deck. Generally, about 5 to 7 GPM of water is used per STPH of solids fed to the screen. The volume of water required should be supplied so that a portion is combined with the solids into a feed box to prepare a slurry feed to the screen.
