The superior physical properties of the mine polyurethane screen, both toughness and rigidity, ensure that the size of the screen gap is stable during the use of the screen, and the stability of the particle size under the screen is ensured to the greatest extent, and it is not easy to block holes.
Advantages of Polyurethane Screens for Mines
The superior physical properties of the mine polyurethane screen, both toughness and rigidity, ensure that the size of the screen gap is stable during the use of the screen, and the stability of the particle size under the screen is ensured to the greatest extent, and it is not easy to block holes.
Mine polyurethane screen has beautiful appearance, optional colors, light weight, simple installation method, low noise, etc., which greatly improves the working environment.
Mine polyurethane screen has outstanding impact resistance, shock absorption function and cold resistance, and it can also have good elasticity and aging resistance at minus degrees Celsius.
Advantages of polyurethane screens for mines
① On the metal wall where the material passes, nail a layer of polyurethane sieve plate to increase the service life of the metal wall: In the case where the buffer slope cannot be adjusted, in addition to increasing the hardness of the steel plate, we can nail a layer of 20mm--30mm on the warehouse wall Thick polyurethane protective panels. Because the hardness of iron ore is high, the surface of polyurethane is smooth and elastic, which can effectively protect the buffer wall and reduce damage.
②Increase the slope of the buffer bin and material transportation channel: The factors affecting the friction coefficient generally include the nature of the material, speed and temperature, load, vibration and smoothness, among which we can change the material and load, as long as we change the buffer The slope of the silo or material transportation channel, increasing the inclination to reduce the positive pressure, reduces the friction in a disguised form, which can reduce the wear of the metal wall and increase the service life. This effect can be achieved by installing a polyurethane screen.
③Take measures to strictly control the particle size of coarse crushing and iron inclusion, and install polyurethane sieves to prolong the service life of the crusher: the ores mined in the mine are irregular and have a large particle size, so they cannot be directly ground into the ball mill for grinding. In order to reduce the cost of the ball mill, the ore needs to be pulverized and then put into the ball mill for dissociation.
④ Jaw crusher or gyratory cone crusher is generally used for coarse crushing. Before the raw ore is put into people, it should generally be crushed, and the particle size should not exceed 650mm. In this way, in order to effectively control this particle size, install a crusher that meets the size of the crusher at the crushing entrance. Polyurethane sieve plate for effective control. Controlling the particle size will reduce the bearing capacity of the jaw crusher, which can effectively protect the jaw plate and prevent the truck from being broken.
