PROBLEM TO BE SOLVED: To stably achieve appropriate rolling granulation by preventing the sticking of a raw material to a fixing member which fixes a rubber liner. SOLUTION: The drum type granulator includes: a cylindrical rotary drum 11; the plurality of rubber liners 13 comprising a rectangular rubber sheet and disposed by being joined in the circumferential direction so as to cover the entire inner peripheral surface of the rotary drum 11; and the plurality of fixing members 14 for fixing the rubber liners to the inner peripheral surface 12 of the rotary drum 11. The fixing members 14 are disposed parallel to the longitudinal direction of the rotary drum 11 along the joint 18 of the rubber liners 13, 13 adjacent to each other in the circumferential direction, and fix the joining margin 13a of the rubber liners 13, 13 adjacent to each other in the circumferential direction so as to clamp it with the inner peripheral surface 12 of the rotary drum 11. At the joint 18 of the rubber liners 13, 13 adjacent to each other in the circumferential direction, the joining margin 13a of at least one rubber liner 13 covers the fixing member 14 so as to wind it.
