In the grinding oil, there are always mixed with oil slick, impurity, slag, etc. It should be cleaned regularly, or the grinding efficiency and lifespan will be reduced largely and finally influence the equipment grinding efficiency. At the same time, when the grinding oil was covered by the closed oil reservoir, the anaerobion will easily breed, this will result in grinding oil invalid. So, to clean the oil slick, impurity, slag out from the grinding oil is very important, in this way we can not only keep a good grinding oil performance but also expand the grinding oil life largely. At last, reduce the grinding oil cost, improve grinding life and efficiency!
