The wear of crushing equipment is a common thing, but how to reduce the wear of crushing equipment? Gold Mine concludes that it is possible to reduce the wear by controlling the coarse crushing particle size and iron inclusion phenomenon, increasing the slope of the buffer bin and the material transportation channel.
For coarse crushing, a jaw crusher or a gyratory cone crusher is generally used. Before the raw ore is put into operation, it should generally be crushed, and the particle size should not exceed 600mm. In this way, in order to effectively control this particle size, install a 600mmx600mm grid screen at the crushing population. Effective control. Controlling the particle size will reduce the endurance of the jaw break, which can effectively protect the jaw plate and prevent the truck from breaking. Generally, an iron remover is installed at the jaw break discharge port to prevent the mine from shoveling the poles. Wait for the harder iron to enter the medium crushing, because the medium crushing equipment and the liner are more than 5 times that of the coarse crushing. Iron picking is still necessary.
Factors affecting the friction of the crusher generally include the nature of the material, speed, temperature, load, vibration and smoothness, among which are the material and load, as long as we change the buffer The slope of the silo or material transportation channel, increasing the inclination angle 9 to reduce the forward pressure, will reduce the friction ftg9 in disguise, so that the wear of the metal wall can be reduced, and the service life can be increased, but this must be under conditions permitting. Under the condition that the buffer slope of the crusher cannot be adjusted, in addition to increasing the hardness of the steel plate, we can nail a layer of 20mm thick polyurethane protection plate to the warehouse wall. It has been concluded that the hardness has a greater impact on the friction coefficient of the polyurethane elastomer Generally speaking, the lower the hardness, the higher the friction coefficient, the smoother the surface, and the smaller the friction. Because the iron ore has high hardness, the polyurethane surface is smooth and elastic, so it can effectively protect the buffer silo wall and reduce damage.
