摘要： A device (1) for the preparation of PCC includes a recarbonation reactor(2) with a first mill (10) and a second mill (11)located inside the recarbonation reactor(2), where each mill (10, 11) includes a first agitation surface (14; 14') and a second agitation surface (15; 15')facing the first agitation surface (14; 14') and roundable as to the first agitation surface (14; 14'). The first mill (10) and the second mill (11) are positioned coaxial and axial staggered so that the relative rotation between their first and second agitation surfaces happens around a common axis (R). The reactor (2) includes an impact and guide surface (17) located in order to invert the sense of the radial movement of the reaction mixture (9) coming out from the first mill (10) and bring this reaction mixture (9) near the common axis (R) before it enters the second mill (11).
