Abstract
A mixer and a method for the mixing of a cementitious slurry, configured to calculate the volume of the cementitious slurry in the mixer in order to produce an improved mixing process and/or an improved cementitious product. The mixer comprises a sensor to measure a parameter of the slurry in the mixer that is used to calculate the volume of slurry in the mixer.
Claims14
A mixer for the mixing of a cementitious slurry, the mixer comprising:
- an inlet for receiving a cementitious material and water;
- a mixing member configured to mix the cementitious material and water to form a cementitious slurry;
- an outlet for dispensing the cementitious slurry;
- a sensor configured to measure a parameter of the cementitious slurry;
- and
- a processor configured to use the parameter measurement to calculate a volume of the cementitious slurry in the mixer;
- wherein
- the sensor comprises an array of thermocouples;
- or
- the sensor comprises an infrared camera, and the mixer comprises an IR window configured to allow the transmission of infrared radiation from the cementitious slurry inside the mixer to the IR camera outside.
