Abstract (en)
The mill comprises at least two rollers (1, 2) supplied by a flow of particles (6). The supply flow rate is such that the bed of particles above the rollers attains a height (h) corresponding to an angle (a) lying between 30 and 80 DEG , preferably between 40 and 65 DEG . Flaps (4 and 5) can usefully channel the particles in order to allow control of the said angle. Application to the milling of cement clinker. <IMAGE>
