How much power will mixer cosumes for 10 minutes?

That depends upon the mixer and the speed. For example, a 600 watt mixer run at full speed for one hour will consume 0.6 kW-hours in one hour. It would consume 0.1 kW-hours in 10 minutes. A 300 watt mixer run at full speed would use half that much, or 0.05 kW-hours in 10 minutes. Running the 300 watt mixer at half power would cut the power consumption in half again, to 0.025 kW-hours per 10 minutes.
