Polyurethane screens can be used in mining, coal and other engineering fields. When mining mines, polyurethane screens make full use of the properties of polyurethane elastomers and show better performance points when they are put into production. Choose polyurethane screens. Great benefits, the polyurethane screen manufacturers will give you a specific introduction:
1. On the metal wall through which the material passes, nail a layer of polyurethane screen to increase the service life of the metal wall: in the case that the buffer slope cannot be adjusted, in addition to increasing the hardness of the steel plate, we can nail a layer of 20mm-- 30mm thick polyurethane protection board. Because the iron ore has high hardness and the polyurethane surface is smooth and elastic, it can effectively protect the wall of the buffer silo and reduce damage.
2. Increase the slope of the buffer bin and the material transportation channel: the influencing factors of the friction coefficient generally include the nature of the material, speed and temperature, load, vibration and smoothness, etc., among which we can change the material and load, as long as we change The slope of the buffer bin or the material transportation channel increases the inclination angle to reduce the forward pressure, and the friction is reduced in disguise, which can reduce the wear of the metal wall and increase the service life. This effect can be achieved by installing polyurethane screens.
3. Take measures to strictly control the coarse crushing particle size and the phenomenon of iron inclusion. The installation of polyurethane screens can prolong the service life of the crusher: the ore mined in the mine is irregular and has a large particle size, so it cannot be directly pulverized by the ball mill. In order to reduce the cost of the ball mill, the ore needs to be crushed until later, and then thrown into the ball mill for dissociation.
4. For rough crushing, jaw crusher or gyratory cone crusher is generally used. Before the raw ore is put into operation, it should generally be crushed, and the particle size shall not exceed 650mm. In this way, in order to effectively control this particle size, the crusher should be installed at the entrance of the crusher to meet the size of the crusher. The polyurethane sieve plate can be effectively controlled. Controlling the particle size will reduce the endurance of jaw breakage, which can effectively protect the jaw and prevent the truck from breaking.
5. Long service life, good wear resistance, and large carrying capacity
Because the polyurethane elastic screen uses steel wire as the skeleton material, and the polyurethane itself has a very high elastic modulus, high-strength impact absorption, high wear resistance, it has high tensile strength, and its load-bearing capacity is rubber screen More than 2.5 times. Compared with ordinary metal screens, its service life is increased by 8-10 times, 3 times that of stainless steel screens, and 3.9 times that of natural rubber. It is currently the world's wear-resistant screen material. The production material of the polyurethane screen is a polymer organic elastomer, which has good abrasion resistance, flexibility resistance and large load-bearing capacity. The raw materials for the production of polyurethane screens have been specially treated to ensure that they will never delaminate under long-term alternating loads.
6, low noise
It is understood that most screens have a lot of noise when they are in use, and in severe cases it will respond to the surrounding environment. However, this kind of comparative polyurethane screens are not the same. No matter which materials are screened during their use, they will not make a lot of noise. The calm screening operation is their big advantage and color. , And because of this, polyurethane screens are very popular.
Therefore, the polyurethane screen really plays a very important role in mining mines, which also brings us a clear direction. We must pay attention to choosing the right size products when purchasing, so as not to cause unnecessary trouble. .
