Enter the bed depth, bulk density, speed of travel, and width of the screen into the calculator to determine the vibrating screen capacity.

Vibrating Screen Capacity Formula

The following equation is used to calculate the Vibrating Screen Capacity.


  • Where VSC is the vibrating screen capacity (tons/hr)
  • D is the depth of the bed (feet)
  • W is the width of the screen (feet)
  • V is the speed of travel (ft/hr)
  • C is the bulk density of the material (tons/ft^3)

To calculate a Vibrating Screen Capacity, multiply the depth of the bed by the width of the screen by the speed of travel, then multiply by the bulk density of the material.

What is a Vibrating Screen Capacity?


A Vibrating Screen Capacity is a measured of the amount of material, in weight, that a vibrating screen can process per unit time. These units are typically tons and hours respectively.

How to Calculate Vibrating Screen Capacity?

Example Problem:

The following example outlines the steps and information needed to calculate Vibrating Screen Capacity.

First, determine the depth of the bed. The depth of the bed in this example, is found to be .5 ft.

Next, determine the width of the screen. The width of the screen for this example problem is measured to be 3 ft.

Next, measure the speed of travel of material moving through the screen. This is found to be 500 ft/hr.

Next, measure the bulk density of the material being sorted. In this case, the bulk density is measured to be .0225 tons/ft^3.

Finally, calculate the Vibrating Screen Capacity using the formula and information above:


VSC = .5*3*500*.0225

VSC = 16.875 tons/hr
