Solution to the damage of the roller surface of Metal roll forming machine
2023-07-25
1. In the process of production and operation, because the materials fed into the roller press are mixed with metal impurities, the roller surface may be directly damaged, resulting in cracks, pits or hard grinding layer collapse on the roller surface. In order to prevent metal objects from entering the roller press, the common method is to add magnetic metal separator (also known as iron separator) and Metal detector on the feed belt machine process line of the roller press, Install a forked flap chute with a quick actuator at the discharge end of the belt conveyor.
2 In some roller press grinding systems, even if the Metal detector detects a metal foreign matter, the Metal detector is arranged in an unreasonable position, and the Metal detector is too close to the unloading place. If the belt conveyor does not have a brake, although the belt conveyor receives an alarm signal for detecting a metal foreign matter and stops in an emergency, the belt conveyor still moves by inertia, and will send the detected metal foreign matter to the silo. So it is necessary to choose high-quality products to avoid misoperation of the control system.
3 When the Metal detector detects the metal foreign matter and stops in an emergency, the operator of the roller press system must carefully and responsibly check and remove the metal foreign matter sometimes hidden under the material layer in time to ensure the normal operation of the roller press.
