Screw Conveyor Flow Rate Calculator

This calculator can be used to determine the flow rate of a screw conveyor based on input parameters such as screw diameter, rotational speed, material density, and loading factor.

Input Parameters

Calculation Results

Calculation Formula

Q = πD²/4 * v * ρ * φ

Where:
Q = Flow Rate (kg/h)
D = Screw Diameter (m)
v = Rotational Speed (rpm)
ρ = Material Density (kg/m³)
φ = Loading Factor

Screw Conveyor Flow Rate Calculator Usage Guide

Learn how to use the Screw Conveyor Flow Rate Calculator and its working principles

How to Use the Calculator

  1. Enter the screw diameter in meters (m).
  2. Enter the rotational speed of the screw in revolutions per minute (rpm).
  3. Enter the density of the material being conveyed in kilograms per cubic meter (kg/m³).
  4. Enter the loading factor (dimensionless), which typically ranges from 0.3 to 0.9.
  5. Click the "Calculate" button to compute the flow rate.
  6. The flow rate will be displayed in kilograms per hour (kg/h).

Working Principle

The flow rate of a screw conveyor is determined by the cross-sectional area of the screw, the rotational speed, the material density, and the loading factor. The formula used is based on the volumetric flow rate and accounts for the material's density and how densely it fills the screw.

Applications

This calculator is useful for engineers and technicians involved in the design and operation of screw conveyors for various industries, including food processing, pharmaceuticals, and bulk material handling.
