Screw Conveyor Flow Rate Calculator















 

Introduction

Efficient material handling is essential in various industries, and screw conveyors play a crucial role in transporting bulk materials. To ensure optimal conveyor performance and prevent overloading, it’s essential to calculate the flow rate accurately. The Screw Conveyor Flow Rate Calculator is a valuable tool designed to assist engineers and operators in determining the flow rate of materials through a screw conveyor. In this article, we’ll explore how this calculator works and how it can be used effectively in material handling applications.

Formula

The Screw Conveyor Flow Rate (Q) is calculated using the following formula:

Q = (60 * π / 4) * D^2 * S * N * a * d * C

  • Q: Screw Conveyor Flow Rate (kg/hr)
  • D: Diameter of the screw conveyor (meters)
  • S: Pitch of the screw conveyor (meters)
  • N: Rotational speed of the screw conveyor (RPM)
  • a: Loading ratio
  • d: Density of the material being conveyed (kg/m^3)
  • C: Inclination factor

The flow rate determined by this formula is critical for ensuring that the screw conveyor operates efficiently without overload or underutilization.

How to Use

Using the Screw Conveyor Flow Rate Calculator is a straightforward process:

  1. Diameter (D): Enter the diameter of the screw conveyor in meters.
  2. Pitch (S): Input the pitch of the screw conveyor in meters.
  3. RPM (N): Enter the rotational speed of the screw conveyor in revolutions per minute (RPM).
  4. Loading Ratio (a): Provide the loading ratio as per your specific application.
  5. Density (d): Input the density of the material being conveyed in kilograms per cubic meter (kg/m^3).
  6. Inclination Factor (C): Enter the inclination factor based on the conveyor’s angle of inclination.
  7. Click the “Calculate Flow Rate” button.
  8. The calculated Screw Conveyor Flow Rate (Q) will be displayed.

Example

Let’s illustrate how to use the Screw Conveyor Flow Rate Calculator with an example:

Suppose you have a screw conveyor with the following specifications:

  • Diameter (D): 0.3 meters
  • Pitch (S): 0.15 meters
  • RPM (N): 30 RPM
  • Loading Ratio (a): 0.8
  • Density (d): 800 kg/m^3
  • Inclination Factor (C): 1.2

Using the calculator:

Q = (60 * π / 4) * (0.3^2) * 0.15 * 30 * 0.8 * 800 * 1.2 ≈ 3,387.24 kg/hr

So, in this example, the Screw Conveyor Flow Rate is approximately 3,387.24 kilograms per hour.
