After the irradiation of the continuous laser, the material forms a pit in the center, and then the molten material is quickly removed by the oxygen flow coaxial with the laser beam to form a hole. Generally, the size of the hole is related to the thickness of the plate, and the average diameter of the blasting perforation is half of the plate thickness, so the blasting perforation diameter of the thicker plate is larger and not round, so it is not suitable for use on parts with higher requirements (such as petroleum screen pipes), and can only be used on waste materials.

It is generally believed that if the belt conveyor drive device configuration is too high, it is a waste of resources. However, for large equipment, if it is too low, it will cause the dynamic tension to increase when the belt is started, and even cause the belt to resonate.

There are many types of belt conveyor cleaners, and the common cleaning devices include hammer cleaners, spring cleaners, alloy rubber cleaners, rotary brush cleaners, empty section cleaners, cleaning rollers, hydraulic cleaners, PUR polyurethane belt cleaners, closed cleaners, carbide scraper cleaners, electric roller brush cleaners, electric vacuum cleaners, rotary cleaners, etc. It is not possible to use all of them on conveyors, so here are a few commonly used cleaners.

​In the process of belt conveyor operation, it is inevitable that some materials or dust adhere to the surface of the conveyor belt, which cannot be completely discharged through the discharge device, at this time, we need a cleaner to clean these attached materials.
