Sand maker is widely suitable for the medium crushing and fine crushing of many types of hard and crisp materials such as rocks, abrasive material, refractory, cement clinker, quartz stone, iron ore and concrete aggregate. During the operation for sand making machine, it is necessary to add some lubrication oil. From the eyes of the sand making machine manufacturers, the selection of lubrication oil also needs to change in different seasons.

In addition, the management of lubrication interval of sand making machine is also important. Lubrication oil has great influence on the maintenance of sand making machine which will affect the service life and working efficiency of sand making equipments. So the operators of sand making machine had better pay enough attention to the selection of lubrication oil. In this article, Henan Hongxing Mining Machinery Co., Ltd. has summed up the experience of lubrication work briefly.

1. As we know, during operation, the sand maker can produce some pollutions such as dust, so the lubrication oil should has strong abilities of antirust and anticorrosion. And in this case, even if there is some impurities in the lubrication oil, the performance of it will not be greatly influenced.

2. The lubrication oil used should possess some certain heat and inoxidizability. This is because that the oil tank of sand making machinery is small and the adding quantity of lubrication oil is not so large, moreover, if the sand making equipment works for a long time, the temperature of each parts will be very high. So the lubrication oils should have strong thermostability.

3. The lubrication oils should has certain stability. In some sand maker manufacturers, the temperature difference between day and night is big. So if the quality of lubrication oil is not high enough, it will form the lubricating film and will not play the role of lubrication.
