1. Polyurethane rubber screen
Due to the low mechanical properties and relatively large toughness of polyurethane, in order to resist the damage of sand and stone falling from the belt conveyor to the screen mesh, there are some requirements for the diameter and thickness of the mesh reinforcement, which can not be too thin or too thin Square swing screen Under the condition of drying surface size, it is unavoidable to reduce the opening rate of the screen, which will reduce the screen permeability. Among the four kinds of screens, the polyurethane screen has a lower sieve permeability.
 Screen material of square swing screen
2. Steel mesh
The reinforcement screen has large mechanical performance, strong resistance to sand and stone impact, smooth and smooth surface of reinforcement, which can reduce the barrier to the moving sand and stone, and has a good opening rate under the condition of the stress performance of the screen mesh, so as to greatly improve the screen permeability.
 Screen quality of square swing screen
3. Steel plate screen
Due to its own factors, the circular opening is often used in the process of use. Because the hole is directly opened on the steel plate, the whole screen surface is smooth in use, which is convenient for the sliding of sand and gravel. However, because the shape of the opening is round, and the sand and stone are mostly irregular polygon, the probability of blocking the round hole is greater than that of the square hole.
 Screen type of square swing screen
4. Square steel screen
The mechanical property of square steel screen is better than that of polyurethane screen. The square swing screen has no disadvantage of polyurethane screen, and the open hole rate and screen permeability of the screen may be obtained.
