1.  Polyurethane sieve plate main properties and characteristics:

1). good wear resistance, long service life, the wear resistance of the steel sieve 3 to 5times,for ordinary rubber sieve more than five times.

2). maintenance quantity small, polyurethane sieve is not easy to damage, long service life, so can greatly reduce the maintenance quantity and maintenance loss.

3). .the total cost is low, although the same specification (area)polyurethane sieve than stainless steel sieve one-time investment (about two times), poly sieve life is stainless steel sieve 3 to5 times, and repair and replacement less, so the total cost is not high, the economy is also very economical.

4). .Moisture performance and work under the conditions of the water as the medium, and in the case of water, oil, media, the friction coefficient of the polyurethane materials lower, more favorable through the sieve, to improve the screening efficiency, and avoid wet particles adhesion, due to the lower coefficient of friction, wear reduction in service life.

5). corrosion-resistant, non-flammable, non-toxic and odorless.

6). mesh sieve unique manufacturing process design, limit size of the particles does not block the sieve.

7). vibration absorption can be good, strong silencer, can reduce the noise, and make the matter on the screen is not easily broken in the process of vibration.

8). due to the characteristics of the poly secondary vibration, polyurethane screen panel has since cleaning effect, so high screening efficiency.

9). saving energy, poly proportion small, much lighter weight than the same size steel sieve, and thus reduce the load on the screening machine, saving power consumption and extend the machine life.

2.Use of the Polyurethane sieve plate 

Metallurgy (iron ore, limestone, fluorite, cooled blast furnace slag, coke and other raw materials), colored, yellow, coal, chemicals, building materials and hydropower projects, abrasive waste disposal, quarry materials and other industries washing, screening , grading and other industries. A variety of sizes and format a new structural model mesh size sieve, especially common on the impact of strong, high hardness, high abrasion resistance requirements of the occasion. In the iron ore crushing and screening, coal grade, gold, building materials and utilities, such as nuclear power projects with a sand and gravel wear screening sieve. Polyurethane elastomer products have been processed in the military, steel, coal, power plants and other mining enterprises, textile machinery, wood processing, food processing, electronic instruments, paper, printing, dyeing, printing and iron processing industry has been widely used .
