Calculations happen locally in your browser. ToolLott does not send these inputs to a server for this tool.
Preliminary engineering screening only. It does not replace project-specific design, applicable codes/standards, manufacturer data, transient/fatigue studies, geotechnical or site assessment, professional review or independent verification.
How to use it
Replace the worked-example values with actual project data. Review the intermediate quantities and visible assumptions before using the result elsewhere.
How the Conveyor Power Calculator works
Screen conveyor drive power from throughput, lift, length, an explicit equivalent resistance coefficient and drive efficiency. The methodology below exposes the production equation, a QA-verified worked example and the boundary between this screen and detailed design.
Calculation breakdown
ToolLott will explain the current inputs and displayed result here.
Material-lift plus resistance conveyor power screen
The production engine evaluates P = m_dot g (H + fL) / eta. It begins by convert throughput from t/h to kg/s., then add vertical lift to the user-entered horizontal resistance-equivalent head fL., and finally calculate mechanical load power and divide by drive efficiency. This keeps the calculation auditable instead of hiding design assumptions behind a single number.
P = m_dot g (H + fL) / etaToolLott evaluates the relationship using the entered units and full numeric precision before display rounding.
| Symbol / input | Meaning | Unit |
|---|---|---|
throughput | Material throughput (t/h) | user input |
length | Conveyor length (m) | user input |
lift | Vertical lift (+) / fall (-) (m) | user input |
resistance | Equivalent horizontal resistance coefficient | user input |
efficiency | Drive efficiency (%) | user input |
Step-by-step method
- Convert throughput from t/h to kg/s.
- Add vertical lift to the user-entered horizontal resistance-equivalent head fL.
- Calculate mechanical load power and divide by drive efficiency.
Worked example
Nina, a project engineer, has a conveyor moving 180 t/h over 120 m with 12 m lift and needs a preliminary drive-power screen before vendor selection.
Example inputs
- Material throughput (t/h): 180
- Conveyor length (m): 120
- Vertical lift (+) / fall (-) (m): 12
- Equivalent horizontal resistance coefficient: 0.03
- Drive efficiency (%): 85
Calculation / processing
Mass flow = 180,000/3600 = 50 kg/s.Equivalent lift = 12 + 0.03 x 120 = 15.6 m; mechanical power = 7.65 kW.Input power = 7.65/0.85 = 9.0 kW.
Use the result as a screening or quantity-planning value and compare it with the project criteria, manufacturer data and applicable engineering requirements before making a design or procurement decision.
Assumptions
- The entered values are representative of the condition being screened and use the units shown on the page.
- The equation models only the stated relationship; omitted system effects are not silently estimated.
Limitations
- This page is not engineering certification and does not replace applicable standards, design loads, manufacturer data, site investigation or competent professional review.
- Results can change materially when real geometry, losses, transients, material properties, duty cycles, safety factors or regulatory criteria differ from the simplified inputs.
Common questions
Is this a final engineering design?
No. It is a transparent screening calculation using the entered assumptions and the stated equation.
Why does the page show assumptions and limitations?
Engineering formulas are only valid within their modelling assumptions; exposing them helps users decide what additional design checks are required.
Should I use the rounded displayed value in later design work?
Use suitable calculation precision and the governing project/standard requirements rather than relying on display rounding alone.

A realistic way Nina could use this tool
Nina is a project engineer.
Nina has a conveyor moving 180 t/h over 120 m with 12 m lift and needs a preliminary drive-power screen before vendor selection.
The scenario is tested with throughput = 180; length = 120; lift = 12; resistance = 0.03; efficiency = 85. Those entries lead to Preliminary conveyor drive power: 9 kW. Because the inputs and result are both shown, Nina can compare the example with real project/source data before reuse.
The worked result is Preliminary conveyor drive power: 9 kW; in this situation that lets Nina a preliminary drive-power screen before vendor selection. If the underlying values change, the example makes clear which inputs need to be updated rather than hiding the assumption. The page also keeps this limitation explicit: Preliminary screening/planning calculation only.
Fictional scenario using realistic example data. For Ready tools, the worked result is tied to the tested example shown in the tool. Replace the figures with your own inputs and independently verify important professional, financial, legal, health or safety decisions.
