About Vibrating Screen Capacity Calculator (Formula)

The Vibrating Screen Capacity Calculator is a valuable tool in the mining, construction, and recycling industries, among others. It allows users to estimate the capacity of vibrating screens, which are essential for separating and sorting materials based on size. By understanding the capacity of a vibrating screen, operators can optimize their processes, improve efficiency, and ensure that their equipment is used effectively. This article will explain the formula used in the Vibrating Screen Capacity Calculator, guide you on how to use it, provide a practical example, and address frequently asked questions.

Formula

The formula for calculating the vibrating screen capacity is:

VSC = D * W * V * C

Where:

• VSC represents the vibrating screen capacity.
• D is the diameter of the screen.
• W is the width of the screen.
• V is the velocity of the material passing through the screen.
• C is the efficiency coefficient of the screen.

How to Use

1. Determine the Diameter (D): Measure the diameter of the vibrating screen in meters.
2. Measure the Width (W): Identify the width of the screen, also measured in meters.
3. Calculate the Velocity (V): Determine the velocity of the material being screened, typically in meters per second (m/s).
4. Find the Efficiency Coefficient (C): This coefficient varies based on the type of material and the specific screen design. It usually ranges from 0 to 1.
5. Input Values into the Formula: Substitute the values of diameter (D), width (W), velocity (V), and efficiency coefficient (C) into the formula: VSC = D * W * V * C.
6. Calculate the Vibrating Screen Capacity: Perform the calculation to find the capacity of the vibrating screen.

Example

Let’s calculate the vibrating screen capacity for a screen with the following parameters:

• Diameter (D): 2 meters
• Width (W): 1 meter
• Velocity (V): 0.5 m/s
• Efficiency Coefficient (C): 0.8

Using the formula:
VSC = D * W * V * C
VSC = 2 m * 1 m * 0.5 m/s * 0.8
VSC = 0.8 cubic meters per second (m³/s)

This result indicates that the vibrating screen can handle a capacity of 0.8 m³/s based on the given parameters.
