Daily maintenance and cleaning methods for polyurethane screens

Rust stains caused by dirt on the surface of polyurethane screens can be cleaned with 10% nitric acid or an abrasive detergent, or a special detergent.

Rainbow-like patterns on the surface of polyurethane high-frequency screens are caused by excessive use of detergent or grease and can be removed with warm water and a neutral detergent. When bleach or various acidic substances adhere to the surface of polyurethane high-frequency screens, they must be rinsed immediately with water, then immersed in an ammonia solution or a neutral sodium bicarbonate solution, and finally cleaned with a neutral detergent or warm water. All equipment and accessories must be regularly maintained and inspected; otherwise, malfunctions will occur.

Vibrating screens are indispensable main equipment in mineral processing and grading operations, and come in many specifications and models. To meet different grading and dewatering requirements, the structure, size, mesh size, and distribution of polyurethane high-frequency screens vary.

The surface of a polyurethane high-frequency screen is usually assembled from multiple polyurethane high-frequency screen meshes. Traditional polyurethane high-frequency screen meshes are usually made using perforation, weaving, or custom welding processes, and are made of carbon steel, stainless steel, or alloy steel. Polyurethane high-frequency screens are susceptible to impact and wear from ore, and the high-frequency vibration of the vibrating screen can easily lead to fatigue cracking of the welds, resulting in a short service life and frequent replacements, severely impacting the production efficiency of the vibrating screen. For dewatering and demineralizing screens with mesh sizes in the range of 0.5mm-3mm, the advantages of polyurethane screen surfaces are even more significant. This product has advantages such as waterproofing, corrosion resistance, and aging resistance, and is easy to maintain. However, excessive tension can affect the screening efficiency and service life of the polyurethane high-frequency screen.

Check the tension of the polyurethane high-frequency screen to avoid excessive tension. Excessive tension will affect the service life of the polyurethane high-frequency screen and may even directly damage the screen mesh.
