What are the types of linear vibrating screen ?Which has a longer service life?
Vibrating sieve screen is a supporting equipment for sand production line, which is mostly used in mining, coal mine, construction, glass factory, petroleum, hardware and other industries. But sometimes in use, the damage is too fast. So which screen material is better and has a longer service life?
What kinds of common screen material are there?
1. Polyurethane rubber screen
Polyurethane has relatively low stress performance and relatively high toughness. In order to resist the damage caused by the sand and stone falling from the belt machine to the screen, the diameter and thickness of the screen ribs cannot be selected too thin or too
Thin, under the condition of the size of the drying surface of the vibrating screen, it is unavoidable to reduce the opening rate of the screen. This will reduce the screen penetration rate. Among the four screens, the screen penetration rate of the polyurethane screen is more low.
2. Reinforcing steel screen
Reinforced screen has a large stress performance, strong impact resistance to sand and stone materials, and the surface of the steel bar is smooth and smooth, which can well reduce the resistance to the sand and stone materials in motion, and can also have good openings under the condition of the screen performance rate,Thus, the screen penetration rate of the screen can be greatly improved.
3. Steel mesh
Due to its own factors, this type of screen is often used for circular openings. Because it uses holes directly on the steel plate, the entire screen surface is smooth during use, which is convenient for the sliding of sand and stone materials. But due to the opening.The shape is round, and the sand and gravel materials are irregular polygons. The probability of blocking the round hole is greater than that of the square hole.
4. Square steel screen
Square steel screens have better mechanical performance than polyurethane screens. The square steel screen does not have the shortcomings of the polyurethane screen, and the opening rate and the screen penetration rate of the screen may be obtained.
