The wear and tear of crushing equipment will increase our unnecessary maintenance costs and cause unnecessary losses. This is not what we want, so how can we reduce the wear and tear of crushing equipment? Listen to experts for your support to deal with crusher wear problems.
First, the factors affecting the friction coefficient of buffer tanks and material transport passages are generally: material properties, speed and temperature, load, vibration, and finish. Materials and loads that we can change are as long as we change buffer tanks or materials. The gradient of the transport passage, increasing the inclination angle 9 to reduce the forward pressure, reduces the frictional force f=tg9 in disguise, so that the wear of the metal wall can be reduced and the service life can be increased, but this must be carried out under conditions permitting. Transformation.
Second, control coarse-grained and coarse iron-clad phenomenon generally use jaw crusher or rotary cone crusher, before the original ore cast, generally should be broken, not more than 600mm size, so that in order to effectively control the size of the broken The Population Department installed 600mmx600mm grid screens for effective control. By controlling the particle size, it will reduce the resistance of the cracks, effectively protecting the jaws and preventing the crushing trucks.
In general, the company installs a deironing device at the discharge opening of the E-breaker to prevent the mine from mining iron rods, shovels, and other hard irons into the smash, because the smashing equipment and lining plate are more than 5 times thicker, and at the same time The crudeness of the meal and the row are also coarse, which have little effect on the lining, but it is still necessary for people to take care of picking iron.
Third, to ensure that the belt cleaner scraper clean Fourth, in the material through the metal wall, nailed a layer of polyurethane plate to increase the life of the metal wall In the case of the buffer slope can not be adjusted, in addition to increasing the hardness of the plate, we can put the warehouse A 20mm-thick polyurethane protective plate on the studs, according to the National Reaction Injection Molding Engineering Technology Research Center (influence factors for the friction coefficient of polyurethane elastomers) concluded that: “Hardness has a great influence on the friction coefficient of polyurethane elastomers. The lower the hardness, the higher the coefficient of friction, and the smoother the surface, the lower the friction. Because of the high hardness of iron ore, the polyurethane surface is smooth and elastic, which can effectively protect the buffer wall from damage.
