  • Method of grinding a mineral material containing at least calcium and metal impurities, and plant suitable for grinding a mineral material containing calcium and metal impurities as they stand
    Patent number: 10569277
    Abstract: A method of grinding a mineral material (10) containing at least calcium impurities implemented in a plant (1) including a grinder (2) and a granulometric selection device, referred to as a selector device (3), able to separate the materials into two fractions. The method includes the following steps: grinding the mineral material by material bed compression with the grinder to obtain a ground material, separating the ground material into a fine fraction and a coarse fraction with the selector device, returning the coarse fraction (13) to the grinder (2) for a further grinding step. At least part of the ground material is subjected to sorting intended to separate the metal impurities from the mineral materials. A plant as it stands, and the method and installation will find a particular use for producing hydraulic binders such as cement.
