  • Splash lubricating system for coal grinding rolls
    Patent number: 4126207
    Abstract: A splash lubricating system for supplying oil to an interior reservoir for the bearings of grinding rolls, comprises an interior oil supply reservoir formed in the hub of the grinding rolls and at least one exterior oil supply line is connected from an exterior reservoir to the interior reservoir of the hub. Oil level indicating means are associated with the exterior oil supply reservoir for indicating changes of oil levels in the interior reservoir and for stopping the driving of the rolls if the oil level should fall below a predetermined amount. Two such exterior reservoirs may be provided, and one is advantageously connected to a separate oil supply tank for replenishing the oil in the interior reservoir of the grinding roller.
