Abstract:
1. Facility for grinding inorganic matter, comprising: a roller press, a first static separator having an intake supplied with raw material, and comprising a first static output for low-granulometry matter and a second static output for matter with larger granulometry, whereby the second output is connected to roller press, a dynamic separator includes an intake connected to the first output, and further includes a first dynamic output for particles having the desired granulometry, and a second dynamic output for matter with larger granulometry connected to an intake of the roller press, a ventilation circuit provided through the first static separator and the dynamic separator in order to participate in the separation, drying, and transport of the low-granulometry particles, wherein the facility further comprises a second static separator having an intake that is solely connected to a roller output of the roller press, and at least a first separator output, for low-granulometry particles, connected to the dynamic separator, whereby the first static separator is fed only with raw material, and wherein the ventilation circuit passes through the second static separator.
