Polyurethane screen plates combined with vibrating screens have been widely used in the screening of fine iron ore, grading of raw coal, gold, building materials, hydropower, nuclear power, engineering sand screening, and other related fields. According to the type, polyurethane sieve plates are divided into combined sieve plates, tension sieve plates and relaxation sieve plates, etc. Due to different uses, variously designed sieve plates have different choices of oligomer polyols. So, how to choose a suitable polyurethane screen plate?

How to choose a suitable polyurethane screen plate?

1. Appearance is the direct standard of polyurethane screen panels. The surface of the polyurethane sieve plate should be smoother and more delicate, and the color of the sieve plate should be pure. There should be no broken strips, burrs, missing materials, mixing, and tight joints.

2. The opening rate is also an important basis for polyurethane screens. The opening rate is a very direct factor affecting the efficiency of screening work. The larger the opening of the polyurethane screen plate, the higher the screening efficiency and output.

3. Whether the mesh structure of the polyurethane screen plate is uniform. Excellent polyurethane screens require uniform screen openings and corresponding standards with minimal tolerances.

4. The connection method of the polyurethane composite sieve plate. The connection method of the polyurethane sieve plate directly affects the screening efficiency. The polyurethane sieve plate requires a tight connection and no leakage to ensure product quality.

5. A good polyurethane screen plate must be tough. In actual production, the polyurethane screen plate is required to have strong elasticity to ensure that the waist does not collapse and is not easy to break during production.
