ABSTRACT:
A roller grinding mill having the grinding roll assemblies pivotally suspended from a frame rotated by a drive shaft, means supplying lubricant and pressure air to the internal structure of the mill for providing primary air seals to keep abrasive matter from working into the bearings with pressurizing the lubricant to provide a source of air internally of the grinding roll assemblies to set up a secondary air seal in the event of a break or leak in the pressure air which can interrupt the primary air seal, and means to monitor or detect a condition in the mill which would result in damage to the bearings if not attended to.
