The present utility model provides a split barrel for a conical twin-screw extruder, which solves the problems of high manufacturing cost and inconvenient maintenance of existing conical twin-screw barrels. It is characterized by comprising: an upper half-barrel, which is semicircular, and the bottom surface of the upper half-barrel is provided with two partially overlapping first semicircular grooves; a lower half-barrel, which is semicircular, and the top surface of the lower half-barrel is provided with second semicircular grooves for matching with the first semicircular grooves; and connecting pieces for connecting the upper half-barrel and the lower half-barrel. The two partially overlapping first semicircular grooves and the second semicircular grooves can be separately processed by ordinary machine tools, and the upper half-barrel and the lower half-barrel are connected by the connecting pieces after processing. The two partially overlapping first semicircular grooves and the second semicircular grooves cooperate to form an ∞-shaped inner cavity, which can effectively reduce the manufacturing cost. Moreover, when the inner cavity of the barrel is worn, the barrel can be disassembled to conveniently repair the worn surface of the inner cavity, enabling repeated use of the barrel.
