STRAIGHT GRAVITY ROLLER CONVEYOR LINE
The unpowered roller conveyor is mainly composed of a drum, a support frame and a transmission device. The roller is the core component of the unpowered roller conveyor, which is usually made of metal or plastic, mounted on a support frame, and connected to other rollers by a transmission device. The surface of the drum is usually covered with rubber or plastic to increase the friction between the material and the drum and ensure the stable delivery of the material.
