摘要： A method and a system for controlling the mixing of raw materials for cement. Component contents of a sample material is obtained at an exit side of a mill system to obtain measured modulus values of hydraulic modulus HM, silica modulus SM, and iron modulus IM of a raw material mixture. Estimated modulus values of the component contents is determined and based on current takeout amounts of the raw materials, a mill system passage characteristic model, a component analyzer passage characteristic model, and preset component contents of the raw materials. Modulus deviation values are calculated based on differences between the estimated modulus values and the measured modulus values, and is passed through a noise removal filter. Future modulus values of the component contents are then calculated based on the raw material takeout amounts, and the preset raw material component contents. To determine predicted modulus values for calculation of updated takeout amounts. The predicted modulus values are adjusted to follow predetermined target values while considering a balance among the modulus values of HM, SM and IM, as well as the capacities of feeders of the raw materials, to calculate the updated raw material takeout amounts.
