Major parts of trommel screen are drum, screen mesh, discharge hopper, support base frame and drive devices. When materials feeding into the drum, on the one hand, materials will make a spiral movement along with drum surface to be screened.
On the other hand, the larger materials will flow forward along the direction of slope and be separated by screen with different meshes. The different materials will fall into different hoppers and then be sent to different products stacks through belt conveyor or manpower.
The main structural components consist of the rotary drum, the screen mesh, the discharge hopper, the support base frame, and the driving system that powers rotation.
Materials are separated based on size. As the drum rotates, smaller particles fall through the designated screen meshes, while larger items travel forward along the slope to the end of the drum.
The combination of the drum's continuous rotation and its inclined installation angle causes materials to tumble and perform a spiral movement along the screen surface.
After passing through the screen mesh, materials fall into corresponding discharge hoppers. They are then transported to designated storage piles using belt conveyors or manual labor.
Yes, by installing screen sections with different mesh sizes along the length of the drum, the machine can separate materials into several distinct size gradings during a single operation.
