Method for detecting mixing amount of mixing material in cement

The invention discloses a method for detecting a mixing amount of a mixing material in cement. The method comprises the following steps: in a cement production line, after the mixing material is added in a cement clinker, extracting a mixing bulk cargo; measuring the content of calcium oxide in the mixing bulk cargo; and determining the content of the mixing material through the measured content of calcium oxide by using a linear relationship between calcium oxide and the mixing amount of the mixing material. According to the method disclosed by the invention, the detection speed of calcium oxide is high, the production can be immediately guided to be regulated, and the stability of the cement can be remarkably improved.
