in recent years, as China's infrastructure construction, increasing, coupled with increasing demand for mineral resources, which makes the Crusher mining machinery and equipment, increasing demand, especially as the Jaw Crusher, impact crusher, hammer crusher, Mobile crusher and cone Crusher.

, crushers and other mining machinery lubrication protection work is just as important, we know that mining machinery and equipment mainly is used for crushing and processing, in its operating loss, broken material with high hardness, therefore lubrication is essential. the mining machine commonly used lubricating oil is primarily to conserve the device operation of the efficiently, reduce friction between parts and reduce losses. the viscosity can be divided into light, medium and heavy three types, in practice, according to the different devices use different types of oil, taking into account temperature, speed, load and other factors, to really play the effect of lubricating oil in order to continuously improve the efficiency of crushing machines and other equipment.
