Cantilever rollers are usually made of advanced new materials that can withstand high temperatures. Among them, the materials that are more resistant to high temperatures include ceramics, mica, silicon carbide, etc. Therefore, the cantilever roller can withstand temperatures of 800-1200 degrees and has a wider range of use. The thermal conductivity of the cantilever roller is very good and the heat exchange capacity is relatively strong. It can also ensure the quality of the product to the greatest extent during use. Another important function of the cantilever roller is to help adjust the running direction and speed of the conveyor belt. By adjusting the position and height of the cantilever, the trajectory and speed of the material on the conveyor belt can be changed, thereby controlling the direction and speed of the material. This adjustment can achieve the transportation effect for materials on the conveyor belt in different processes. Cantilever rollers can also reduce damage and leakage of materials during transportation.
