PURPOSE:To reduce grinding action in such a way that very small bosses which slidingly contact a pusher are provided at the lower face of a casing of a cylindrical conveyor to convey coke particle, and an interval is secured between the pusher and the casing. CONSTITUTION:A pusher 14 has its center connected to a chain 6 by a discoid which is a little smaller in its diameter than the bore of a horizontal return casing 4, and it is fixed multitudinously at the determined interval. Hereat, bosses 15 are fixed on the left and right sides in the longitudinal direction at the bottom face of a horizontal conveying path 2 which is one and a half times or so as large as the pusher 14, and the face which slidingly contacts the pusher 14 of the boss is made to be linear contact. By constituting such as this, since the pushers 14 have voids between the insides of the conveying path 2 in the horizontal conveying path 2, particle can be conveyed almost without producing any grinding action. |
