Mixer cycle time - Batch cycle time - Mixing processes

The mixer cycle time should not be confused with the mixing time. Although the mixing time is included in the cycle time, the cycle time covers actually all the process steps to be completed to load materials to the mixer, mix and discharge. It is the time required to complete the batch, it does not apply in continuous processes. 2.

Mixing (process engineering) - Wikipedia

In industrial process engineering, mixing is a unit operation that involves manipulation of a heterogeneous physical system with the intent to make it more homogeneous.Familiar examples include pumping of the water in a swimming pool to homogenize the water temperature, and the stirring of pancake batter to eliminate lumps (deagglomeration).. Mixing is performed to allow heat and/or mass ...
