The utility model discloses a cylinder screen. The cylinder screen comprises a feeding end, a screen drum main body and a discharging end, and is fixed on a frame through support wheels. The cylinder screen is characterized in that the feeding end of a screen drum is provided with a speed reducer; the speed reducer is used for driving a bull gear connected to the end of the screen drum to rotate; three groups of support wheels are arranged on the outer side of the cylinder screen; a feeding pipe is connected with the screen drum main body; the screen drum main body is cylindrical; the screen drum main body is 7.5 meters in length and is 1.0-1.5 meters in diameter; a helical device is arranged on the inner screen surface of the screen drum; the helical device is positively welded on the inner side of the screen drum at the screw pitch of 200-400 millimeters, and the helical height is 100-150 millimeters; a round-table-shaped screen drum is arranged at the discharging end of the cylinder screen. By adopting the cylinder screen, the problems of difficulty in discharging on the cylinder screen and reduction of equipment processing capacity are solved, the screening area is increased; meanwhile, the helical device is arranged on a screen surface, thereby lowering the moisture of materials on the screen, discharging the materials on the screen forcedly in time, and reducing the maintenance cost.
