Polyurethane screen plates can be used in mining, coal and other engineering fields. When mining, there are great advantages in choosing polyurethane screen plates. Let me introduce it to you in detail:

Nail a layer of polyurethane screen plate on the metal wall where the material passes to increase the service life of the metal wall: when the buffer slope cannot be adjusted, in addition to increasing the hardness of the steel plate, we can also nail a layer of 20mm-30mm thick on the warehouse wall of polyurethane protective panels. Due to the high hardness of iron ore, the surface of polyurethane is smooth and elastic, which can effectively protect the walls of the buffer bin and reduce damage.

Increase the slope of the buffer bin and material conveying channel: Factors that affect the friction coefficient generally include material properties, speed and temperature, load, vibration, smoothness and other factors. Among them, what we can change is the material and load. As long as the slope of the buffer bin or material conveying channel is changed, the inclination angle is increased, the forward pressure is reduced, and the friction is reduced in disguise, the wear of the metal wall can be reduced and the service life can be improved. This effect can be achieved by installing polyurethane screens.

Measures should be taken to strictly control the coarse crushing particle size and iron inclusions, and the installation of polyurethane screens can extend the service life of the crusher: The ore mined in the mine is irregular and has large particle size, and cannot directly enter the ball mill for grinding. In order to reduce the cost of the ball mill, the ore needs to be crushed and put into the ball mill for dissociation.

Generally, jaw crusher or rotating cone crusher is used for coarse crushing. Generally, the raw ore is crushed before being put into production, and the particle size does not exceed 650mm. In this way, in order to effectively control the particle size, a polyurethane screen plate that conforms to the size of the crusher should be installed at the crushing inlet for effective control. If the particle size is controlled, the bearing capacity of the jaw plate will be reduced, effectively protecting the jaw plate and preventing the truck from breaking.
