Abstract
A facility for grinding inorganic material include a roller press, a first static separator having an intake supplied with raw material, a dynamic separator having an intake connected to a first output of the first static separator, a ventilation circuit provided through the first static separator and the dynamic separator, and a second static separator having an intake that is connected to an output of the roller press. The first static separator includes two outputs, one for low-granulatory matter and one for larger granulatory matter, whereby the second output is connected to the roller press. The dynamic separator further includes a first output for particles having the desired granulometry and a second output for matter with larger granulometry connected to an intake of the roller press. The ventilation circuit participates in the separation, drying, and transport of low-granulometry particles.
