Advantages of polyurethane sieve plate
Polyurethane sieve plate is a kind of polyurethane resin product, which can be used in coal washing plant, coking plant, mine, power plant, dredging company, metallurgy, petroleum, petrochemical and other industries.Compared with other sieve plates, polyurethane sieve plates have the advantages of high porosity, light weight, good shock absorption, low noise and good wear resistance.
What specific advantages does polyurethane sieve plate have?
1. Long service life and large carrying capacity.
Since polyurethane elastic sieve plate is made of steel wire rope as the skeleton material, and polyurethane itself has a very high elastic modulus, high strength to absorb the impact force, high wear resistance, so it has a very high tensile strength, its carrying capacity is more than 2.5 times that of the rubber sieve plate.Its service life is improved 8-10 times compared with ordinary metal screen plate, 3 times of stainless steel screen surface, 3.9 times of natural rubber.
The production material of polyurethane sieve plate belongs to polymer organic elastomer, which has excellent abrasion resistance, flexural resistance and large bearing capacity.The raw material of polyurethane sieve plate has been specially treated to ensure that it will never delaminate under long-term alternating load.
2. High screening efficiency.
Screen surface of its internal cleaning performance, no plugging hole, screen efficiency.For polyurethane strong water permeability, big cone Angle of mesh (140 °), so it can effectively prevent the fine grained material wet adhesion, thus suitable for wet screening of fine material classification.
3. Wide application range and stronger professional applicability.
Polyurethane screen plate is used in hydropower station, building materials and other metal mining.Screening of various materials within the range of 0.1mm-170mm, whether dry or wet, will not affect the screening efficiency.Product water resistance, corrosion resistance, aging resistance, easy to replace and maintain.Polyurethane low density, can reduce production unit consumption, so it can adapt to the development of large-scale screen machine.
4. High screening accuracy.
The production process of polyurethane sieve plate adopts the mold casting molding process, with accurate pore size, high screening quality, and the granularity of materials under the screen can well meet the requirements of users.Easy installation, convenient maintenance.
5. Low working noise.
According to the actual measurement, the same screen machine using polyurethane screen plate than metal screen plate can reduce noise 5-20 db, and greatly reduce dust flying, so that the production site has a quiet working environment.
6. Remarkable economic benefits.
Although the price of polyurethane rubber screen surface is higher than that of metal screen surface, if factors such as screening efficiency, maintenance cost and service life are taken into account, it can be found that the overall benefit of polyurethane rubber screen surface is better than that of ordinary metal screen surface.According to investigation, every use of a ton of polyurethane rubber sieve plate can save 45 tons of steel.Saving more than 40,000 yuan in maintenance costs.
The above is a brief introduction of the advantages of polyurethane sieve plate, we hope to help you in the selection of sieve plate.
