Mining High Frequency Screen

Polyurethane screens are used in many fields, such as mining, coal and other projects. Polyurethane screens are used. When mining, it is of great benefit to choose polyurethane screens. The following Mining High Frequency Screen Supplier introduces you to the benefits of using polyurethane screens in the mining process.

Mining High Frequency Screen

1. Take measures to strictly control the coarse broken particle size and iron trapping phenomenon, and install the polyurethane screen to 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 milled in the ball mill. In order to reduce the cost of the ball mill, the ore must be crushed to the future and then put into the ball mill for dissociation. The dissociation stage before entering the ball mill is the crushing stage of the beneficiation. The general crushing process is: coarse crushing-> medium crushing-> screening, screening After the sieve-> ball mill; after sieving-> fine broken-> re-screening, this is a common three-stage one-closed crushing process.

Generally, jaw crusher or gyratory cone crusher is used for rough crushing. Before the original mine is put into the crusher, it should generally be crushed. The particle size should not exceed 650mm. In order to effectively control this particle size, install the polyurethane that meets the size of the crusher at the crushing entrance Screens for effective control. Controlling the particle size will reduce the bearing capacity of jaw breaking, which can effectively protect the jaw plate and prevent the broken truck.

2. Increase the slope of the buffer bin and material transportation channel.

The influencing factors of friction coefficient are generally: material properties, speed and temperature, load, vibration and smoothness and other factors, among which we can change the material and load, as long as we change the slope of the buffer bin or material transportation channel, increase the inclination In order to reduce the forward pressure, 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.

Third, nail a layer of Urethane Screen Mesh on the metal wall through which the material passes 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 the warehouse wall with a layer of 20mm--30mm thick polyurethane protection board. The hardness has a greater influence on the friction coefficient of the polyurethane elastomer. In general, the lower the hardness, the higher the friction coefficient, the smoother the surface, and the lower the friction. Because the iron ore has high hardness and the polyurethane surface is smooth and elastic, it can effectively protect the buffer tank wall and reduce damage.
