The high-efficiency biomass fuel roller press as claimed in any one of claims 1 to 6, wherein the roller surface is provided with die holes for extrusion forming and tooth columns for extrusion forming at intervals; the arrangement sequence of the die holes and the tooth columns in the axial direction of the roll surface is that a ring of die holes is connected with a ring of tooth column rings, a tooth column ring is arranged between the die hole rings and the die hole rings, and the tooth columns on the roll surface of the driving roll ring are meshed with the die holes on the roll surface of the driven roll ring; the end surface of the tooth column is not smaller than the aperture of the die hole.

8. The efficient biomass fuel roller press as claimed in claim 7, wherein the toothed column and the die hole of the roller ring are arranged with replaceable wear-resistant sleeves, respectively.

9. The efficient biomass fuel roller press as claimed in claim 8, wherein the toothed column wear-resistant sleeve not only protects the toothed column, but also protects the roller surface except the position of the die hole, protects the whole roller ring surface and presses on the die hole wear-resistant sleeve to limit the movement of the die hole wear-resistant sleeve, and two sides of the toothed column wear-resistant sleeve and two roller ring side plates are fixed by bolts; the die hole wear-resistant sheath is a square column type and/or cylindrical wear-resistant sheath.

10. The efficient biomass fuel roller press as claimed in any one of claims 1 to 6, wherein the diameters of the driven roller ring and the driven roller ring are the same, the diameter of the roller ring is in the range of 1 to 2m, and the axial length of the roller ring is 1 to 2 m.
