Abstract: A method for pretreating biomasses to allow their subsequent conversion to biofuel comprises the following steps:—a) causing the biomasses to pass through a first mechanical reduction device (1) to enable the biomasses to be reduced in size to smaller-sized particles;—b) placing the particles on a particle filtering grille so that particles (P1) smaller than a predetermined size pass through the grille and feed out of the first mechanical reduction device (1);—c) making the particles (P1) which are smaller than the predetermined size pass through a first particle classifying device (2) to allow the particles (P1) to be divided according to size into a first fraction (f1) of coarse size particles and a second fraction (f2) of fine size particles.
