  • Publication number: 20210394133
    Abstract: A method for operating a mixing apparatus of a manufacturing plant comprises supplying multiple powdered products to the mixing apparatus. An inlet mass flow rate of the multiple powdered products into the mixing apparatus and a weight of the multiple powdered products in the mixing apparatus are measured. The multiple powdered products in the mixing apparatus are mixed to form a mixed product. The weight of the multiple powdered products in the mixing apparatus and an outlet mass flow rate of the mixed product from the mixing apparatus are predicted based on the measured inlet mass flow of the multiple powdered products. The predicted outlet mass flow rate of the mixed product from the mixing apparatus is corrected based on the measured weight of the multiple powdered products in the mixing apparatus.
