The classification of vibrating screens is complex and diverse, but can be simply divided into four types based on the different material suppliers: Q235 carbon steel vibrating screen, 304 stainless steel vibrating screen, 316L vibrating screen, and PVC vibrating screen. The low cost of carbon steel vibrating screens is closely related to the material's susceptibility to rusting. However, in the selection process of vibrating screens, considering cost-effectiveness, Q235 carbon steel material is a suitable choice for non pharmaceutical and food industry users when screening non corrosive materials. However, during long-term screening, cleaning, and maintenance work, Q235 carbon steel material is inevitably prone to rusting,Vibration screen manufacturer(Jinhe Machinery) will provide a detailed introduction on how to deal with the rusting problem of carbon steel vibrating screens.

How to solve the rusting problem of Q235 carbon steel vibrating screen

The maintenance process of the vibrating screen cannot be separated from the cleaning steps. Q235 carbon steel vibrating screen is prone to rusting during long-term operation and cleaning. Rust spots not only affect the stiffness and wear resistance of the carbon steel vibrating screen, but also pose a risk of contaminating the material, which needs to be removed and prevented in a timely manner. Common solutions includeCarbon steel vibrating screenThere are three main methods for addressing rusting issues:

1. Use high-pressure water to assist in rust removal of carbon steel vibrating screen

Using a high-pressure water gun to clean the rust spots on the surface of carbon steel is more labor-saving and convenient, without dust pollution, and does not cause additional wear and damage to the equipment. It has a lower cost, and the rust removal efficiency and effect are relatively objective. However, the rust zone of steel plates has a significant impact on the wet rust removal performance of paint coatings.

2. Use a wire brush to remove rust spots from the carbon steel vibrating screen

This method is suitable for situations where there are few rust spots and the rust is small, such as when parts of the equipment are rusted. However, this method has low efficiency and can cause wear and damage to the surface of the equipment. The resulting scratches will also increase the difficulty of equipment cleaning and maintenance in the future

3. Sandblasting treatment on the surface of carbon steel vibrating screen

Sandblasting rust removal is a process that uses compressed air as a power source to form a high-speed jet beam that sprays copper ore, quartz sand, diamond sand, iron sand, and other materials onto the surface of the equipment that needs to be treated, removing all dirt such as rust on the surface of the equipment. Compared to the two rust removal methods mentioned above, sandblasting requires certain operational skills, specialized sandblasting rooms and equipment, and the equipment surface needs to be polished to remove rust, then coated with a layer of protective liquid, and finally pushed into the sandblasting room for sandblasting treatment.

Although sandblasting rust removal is complicated and generates additional dust pollution to the environment during the process, the rust removal effect is very obvious. The carbon steel vibrating screen treated with sandblasting not only has a beautiful appearance but also has a better effect on improving the service life of the equipment.

The above are common rust removal methods for carbon steel vibrating screens. In fact, in the normal production process, how to prevent and slow down the rusting of Q235 material vibrating screen through effective measures is more fundamental. The carbon steel vibrating screen produced by Jinhe vibrating screen manufacturer will be sprayed with a layer of paint on the surface of the equipment after assembly, which not only looks more beautiful, but also effectively isolates the contact between air, moisture, and carbon steel, effectively delaying and improving the rusting situation of the carbon steel vibrating screen. Moreover, the carbon steel vibrating screen is usually welded using gas shielded welding during the welding process, and the remaining welding points are prone to oxidation and rusting. Therefore, JinheVibration screen manufacturerFine polishing treatment is carried out on all solder joints to ensureCircular vibrating screenThe outer surface is smooth and flat, without any burrs or protrusions, which not only simplifies cleaning and maintenance, but also effectively delays the rusting speed of the carbon steel vibrating screen.
