The specific embodiment

Referring to Fig. 1-7, the disk body of flat die disks is divided into dish 1 and lower wall 2, and the interior circle of effective blanking area of last dish and cylindrical be along the annular deflector chute 8 of establishing 5-10 millimeters week, makes the die orifice that accumulates in that blanking is obedient to.Last dish is divided into many row's patrix modular rings 3 from the outside deflector chute of interior deflector chute; lower wall is established and the corresponding counterdie modular ring 4 of last dish; the all five equilibriums in last rim are trapezoidal die orifice 6,7 of some equal fans and nib 11; establish the

trapezoidal nib

15,17 of corresponding with it some fans vertically downward following rim week, make the biomass fuel briquetting be obedient to the moulding blanking.Top, space is provided with 3-10 degree chamferings 13 of 5-15 millimeters of vertical height in the mould at the die orifice 12 left and right two ends of last dish, inside and outside two upper lateral parts are provided with 10-15 degree chamferings 14 of 5-10 millimeters of vertical height, it is outer little trapezoidal in big that space lateral cross section in the mould of the trapezoidal die orifice of fan is formed, the longitudinal cross-section forms up big and down small trapezoidal, and it is compact formed that raw material is able under the material resistance effect of pressurization.Be provided with a plurality of dowel holes that are used to assemble 10,16 at upper and lower dish, assembly precision is improved in the correction of being convenient to be linked and packed location.The interior circle of upper and lower dish and cylindrical set up vertical countersunk head screw hole of some five equilibriums and screw 9 separately, two flat die disks are connected be tightened to whole flat die disks.
