Selecting the right screw conveyor starts with understanding its capacity. An incorrectly sized conveyor can lead to bottlenecks, excessive power consumption, product damage, and reduced production efficiency. Proper screw conveyor capacity calculation ensures smooth material flow and maximum operational performance.
What is Screw Conveyor Capacity?
Screw conveyor capacity refers to the amount of material that can be transported by the conveyor within a specific period of time, usually measured in kilograms per hour (kg/hr) or tons per hour (TPH).
The capacity depends on screw diameter, pitch, speed, material density, and loading efficiency.
Why Capacity Calculation Matters
- Prevents material overflow
- Improves production efficiency
- Reduces energy consumption
- Optimizes equipment performance
- Increases equipment lifespan
- Ensures accurate system design
Screw Conveyor Capacity Formula
The capacity of a screw conveyor is generally influenced by screw diameter, pitch, speed (RPM), and material characteristics.
Engineers use standard calculation methods to determine the theoretical and actual conveying capacity based on application requirements.
| Parameter | Description |
|---|---|
| Screw Diameter | Overall diameter of screw flight |
| Pitch | Distance between flights |
| RPM | Rotational speed of screw |
| Material Density | Weight per cubic meter |
| Loading Efficiency | Percentage of screw fill level |
Factors Affecting Screw Conveyor Capacity
- Screw Diameter
- Screw Pitch
- Conveyor Length
- Inclination Angle
- Material Bulk Density
- Material Flowability
- Motor Power
- Operating Speed
A larger diameter and higher RPM generally increase conveying capacity, but excessive speed may cause material degradation.
Typical Capacity Examples
| Screw Diameter | Typical Capacity Range |
|---|---|
| 100 mm | 1 – 5 TPH |
| 150 mm | 5 – 12 TPH |
| 200 mm | 10 – 25 TPH |
| 250 mm | 20 – 40 TPH |
| 300 mm | 35 – 70 TPH |
