The present utility model discloses a twin‑screw extruder and a barrel thereof. The twin‑screw extruder barrel comprises: a barrel base provided with a barrel inner bore extending axially; a pair of main pressure channels symmetrically arranged on both sides of the barrel base and extending axially parallel to the barrel inner bore; a plurality of branch pressure channels arranged symmetrically on both sides of the barrel base in pairs, spaced axially parallel to the barrel inner bore, and all in intersecting communication with the main pressure channels and the barrel inner bore; a plurality of elastic structures arranged in one‑to‑one correspondence with the branch pressure channels, inserted into the barrel base, with their bottom ends disposed at the intersections of the branch pressure channels and the barrel inner bore. The present invention can balance the fluid pressure in the barrel, improve the stability of slurry products, provide certain pressure buffering capacity, increase slurry residence time, and achieve more sufficient slurry mixing.
