Can it be mixed for too long?

The ultimate goal of mixing is to get one or more products homogeneous. After a certain mixing time, the mixture will not get any better. In some cases the product will segregate due to mixing for too long. Mixing longer than necessary can potentially result in heat generation and product damage. Product damage can occur, especially visible with extruded products. Unnecessary energy consumption and wear and tear on the installation are also disadvantages of unnecessarily long mixing.
