Claims (5)

BACKGROUND OF THE INVENTION 1. A method for molding briquettes from a polydisperse material, comprising filling the press chamber with the material to be treated, densifying it and pressing it with a die in a matrix through backpressure and stretching the briquette with a tazidlamate channel, characterized in that, in order to reduce energy loss, pre-densification is provided. and briquette stretching is carried out in a single operation while maintaining a constant pressure by increasing the cross section of the matrix channel. 2. The method according to claim 1, wherein the pre-thickening is achieved after several strokes of the die. 3. A device for pressing briquettes of a polydisperse material comprising a compression chamber, a punch with a stirring drive, and a matrix with movable walls connected to the pressure elements fixed to the levers, characterized in that it is provided with an eccentric shaft (4) kinematically connected to punch and connecting rods (7) connecting the concentric shafts (4) to the levers (3) · 4. Apparatus according to claim 3, characterized in that the frequency of the eccentric shaft (4) is a proportion of the passage frequency. 5. Apparatus according to claim 3, characterized in that it comprises a flywheel (6). 251907
