Mixer and a method of mixer control.

摘要

In a mixer comprising a body 1 defining a mixing chamber 2 in which two rotors 3 and 4 are rotatably mounted, a processability sensing system 9 is disposed in a port 8 in the body 1. 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 11 operative to control mixing characteristics. This enables mixing to be closely controlled to provide a better product.
