Therefore, in order to reduce the wear of barite ore grinding plant gear, it is necessary to use standard oil and select tangent lubrication method in strict accordance with barite mill lubricating oil.Two aspects should be paid attention to when selecting lubricating oil. On the one hand is the viscosity of lubricating oil, on the other hand is the oiliness of lubricating oil.When selecting the lubrication method, it is necessary to ensure whether the lubrication method is reasonable and whether the lubrication is.At present, the common lubrication methods of barite mill Gear include manual lubrication, oil pool lubrication, dripping oil lubrication and spray lubrication.
