Mixer Power Load with estimated agitator load of 45 kW: a worked example
This scenario runs the mixer power load calculation on the strong side: estimated agitator load of 45 kW, with every other input held at its documented default. estimating agitator load for a mixing step, utility check, or batch cost review
The inputs for this scenario
- Estimated agitator load: 45 kW (raised for this scenario; the documented default is 18)
- Viscosity and duty service factor: 1.25 x (unchanged)
- Planned mixing runtime: 3.5 hr (unchanged)
Working through the calculation
- Applying the documented formula (Mixer power load = estimated agitator load × service factor) to the inputs above produces each figure below.
- At this operating point the engine returns 56.25 kW for total load, the number this scenario is built around.
- At this operating point the engine returns 16.07 kW / hr for mixer power per mixing hour.
- At this operating point the engine returns 45 kW for estimated agitator load.
- At this operating point the engine returns 1.25 x for viscosity and duty service factor.
How this compares with the baseline
- Against the tool's baseline example, where estimated agitator load sits at 18 kW and the headline result is 22.5 kW, this scenario comes in 150% above the baseline at 56.25 kW.
- Use it when sizing or de-rating a mixer motor, verifying a drive can handle a thicker product, or estimating draw for a new batch recipe before commissioning. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
