One kind of a double inlet Mill calculated amount of powder

The present invention discloses a double inlet and a calculation method of the amount of powder mill, comprising the steps of: A: Construction of double inlet and the amount of flour mill model; B: Historically station mill pulverizing system selected data, the selected data satisfies coal conservation of mass, conservation of mass and coal to coal mass conservation three conditions; C: step B using the selected data, using the least squares method to the double inlet mill powder volume model training model, calculating undetermined coefficient; D: obtained in step C are coefficients determined in step a is substituted constructed with double inlet and the amount of flour mill model, the computing double inlet mill the amount of flour. The present invention is capable of double inlet flour mill accurately calculate the amount, it is possible to enhance the stability and economy of operation of the unit, the unit load to improve responsiveness.
