Abstract
A lubricating system for bearing shoes supporting a drum of a crusher for rotation and defining a lubricating oil basin between an upstream and downstream end, in the direction of rotation, comprises a low pressure oil pump operable to deliver lubricating oil to the upstream end of the bearing shoes during rotation of the drum, a high pressure pump operable to deliver lubricating oil to the basin at the start of rotation, and thermocouples arranged to measure the temperature of the bearing shoes close to their gliding surfaces, the thermocouples controlling the high pressure pump operation in response to a temperature sensed by the thermocouples and exceeding a set value.
