Banana screen is mostly adopt polyurethane screen plate, so what are the advantages of polyurethane sieve plate? This article will give a detailed introduction:
1. Long service life and large bearing capacity.
Due to the use of polyurethane elastic screen wire rope as the skeleton material, coupled with the polyurethane itself has a very high elastic modulus, high strength absorption impact force, high wear resistance, so it has a very high tensile strength, its bearing capacity is more than 2.5 times the rubber screen. Its service life compared with ordinary metal screen improves 8-10 times, it is 3 times longer than stainless steel screen surface and 3.9 times longer than natural rubber,it is currently the world's best wear-resistant screen surface material. Polyurethane screen production material is a polymer organic elastomer, with excellent wear resistance, flexing resistance, large bearing capacity. The raw material of polyurethane screen has been specially treated to ensure that it will never delaminate under long-term alternating load.
2. High screening efficiency.
The screen surface has self-cleaning performance, no blocking hole and high screening efficiency. Due to the strong permeability of polyurethane, screen cone angle (140°), it can effectively prevent the adhesion of wet fine particles, so it is suitable for the screening and grading of wet fine particles. Polyurethane screen plate of banana screen is made of imported raw materials, its elastomer and good tension performance, effectively avoid hole blocking phenomenon under dynamic conditions.
3. Wide application range, professional applicability is stronger, suitable for any type of banana screen and can be made.
Polyurethane screen is professionally used in hydropower station, building materials and other metal mining.The screening of various materials in the range of 0.1mm - 170mm, whether dry screening, wet screening does not affect the screening efficiency. The advantages of polyurethane screen surface are more fully demonstrated for dehydration and disintermediation in the range of 0.5m - 3mm. Water resistance, corrosion resistance, aging resistance, easy replacement and maintenance. Polyurethane has small density (1.32kg/ m 3), lighter weight than the metal screen surface, can reduce the production of single consumption, so it can adapt to the development requirements of large screen machine.
4. High screening accuracy.
The production process of polyurethane screen mesh adopts mold casting process, accurate aperture, high screening quality, the granularity of the material under the screen can well meet the requirements of users. Simple installation, easy to change and repair, the product is suitable for any type of screening machine, light weight, for on-site installation or change and repair, greatly reduce the workload.
5. Low working noise, in line with the national specification of environmental noise standards. According to the actual determination, the same banana screen using polyurethane screen than metal screen can reduce noise 5-20 decibels, and greatly reduce dust flying, so that the production site has a quiet clean working environment.
6. Significant economic benefits.
Although the price of polyurethane rubber screen surface is higher than that of metal screen, if the screening efficiency, maintenance cost, service life and other factors are considered comprehensively, it will be found that the overall benefit of polyurethane screen surface is much better than that of ordinary metal screen surface. According to the investigation, every use of a ton of polyurethane rubber sieve plate can save 45 tons of steel. Save maintenance cost more than 40,000 yuan. So polyurethane screen surface instead of steel screen surface will be the inevitable choice of the vast majority of enterprises in the future.
