Abstract
In a mixer comprising a body defining a mixing chamber in which two rotors are rotatably mounted, a processability sensing system is disposed in a port in the body. The system is operative to monitor the flow and deformation characteristics of the material being mixed. It is connected to a feedback control loop which leads to a computerised control operative to control mixing characteristics. This enables mixing to be closely controlled to provide a better product.
