A method for the treatment of granular grinding stock or grinding stock mixture by way of controlled mechanical size reduction by means of a grinding mill or a combination of several grinding mills, comprising the steps of: - correctly proportioned packaging of the grinding stock or the grinding stock mixture, wherein the grinding stock mixture is composed according to a recipe; - storing of first data for controlling the grinding process in accordance with the properties of the grinding stock and/or the recipe of the grinding stock mixture; - storing of second data related to the manufacturer and/or distributor of the grinding stock or the grinding stock mixture as well as of third data related to the origin and/or properties and/or minimum consumption periods or shelf life information related to the grinding stock or the grinding stock mixture; - attaching to, inserting into, applying onto or connecting a data memory unit to the package, wherein the data memory unit is machine readable, in particular optically readable or via radio interface; - automatically activating the grinding mill by means of a grinding mill control unit which is capable of reading out the respective data memory unit of the respective package, when the package has been transported into the proximity of the grinding mill; - executing the mechanical size reduction of the grinding stock or the respective grinding stock mixture while resorting to the first data together with a verification of information according to the third data, and - automatically finishing the grinding process with a finished message, wherein the control unit logs the respective grinding process in a random-access memory while resorting to the second data. - correctly proportioned packaging of the grinding stock or the grinding stock mixture, wherein the grinding stock mixture is composed according to a recipe; - storing of first data for controlling the grinding process in accordance with the properties of the grinding stock and/or the recipe of the grinding stock mixture; - storing of second data related to the manufacturer and/or distributor of the grinding stock or the grinding stock mixture as well as of third data related to the origin and/or properties and/or minimum consumption periods or shelf life information related to the grinding stock or the grinding stock mixture; - attaching to, inserting into, applying onto or connecting a data memory unit to the package, wherein the data memory unit is machine readable, in particular optically readable or via radio interface; - automatically activating the grinding mill by means of a grinding mill control unit which is capable of reading out the respective data memory unit of the respective package, when the package has been transported into the proximity of the grinding mill; - executing the mechanical size reduction of the grinding stock or the respective grinding stock mixture while resorting to the first data together with a verification of information according to the third data, and - automatically finishing the grinding process with a finished message, wherein the control unit logs the respective grinding process in a random-access memory while resorting to the second data. <EOS>
