According to the characteristics of the mining machinery in the actual situation, the ultra-fine grinding mill equipment has quite strict requirements on the lubricating oil, as follows:
First, because the volume of the
ultrafine mill and the volume of its oil tank are relatively small, it is easy to have a high oil temperature at work, which requires the lubricating oil to have better oxidation resistance and thermal stability.
Second: Because the working environment of the ultra-fine grinding mill is very bad, dust and moisture are relatively large, and the lubricant is easily contaminated by the impurities of these external environments, so the lubricating oil must have good rust resistance and resistance. Corrosive. Only in this way, when the lubricating oil is affected by the external harsh environment, its performance will not be greatly changed.
Third: The working environment of the ultrafine grinding mill equipment is generally outdoors, so the working environment is affected by temperature changes, especially when the temperature difference between winter and summer is relatively large. In some areas, the temperature difference between day and night is relatively large, so the viscosity of the lubricant is constant. To be less affected by temperature, this aspect requires that it will not lead to a low viscosity when the temperature is high, and it cannot be used as a lubricant. On the other hand, it must be avoided when the temperature is low and the viscosity of the lubricant is too low. The difficulty of starting and running.
Fourth: There are some mining machinery that are prone to fire or explosion. Of course, the lubricating oil is required to have a certain degree of flame resistance and cannot be lubricated with flammable mineral oil. Fifth: Finally, the seal of the lubricant must be good so as not to damage the seal and affect the effect of the lubricant. Caused some unnecessary danger.
