Abstract

A grinding roller for roll crushing mills, in which the axle is retained in a roller amount provided with a barrier air connection. The axle, furthermore, carries a roller hub connected with a roller shell, over inner bearings lubricated by splash lubrication. A measuring sensor reaches into the oil sump and is led through a core bore in the axle. End faces of the axle are surrounded by covers placed on the roller hub and on the roller mount while leaving gaps. Bores connect the respective gaps with the core bore, and these bores pass from both facing ends through the axle. One of the bores extending out from the rspective gap facing the interior of the mill, passes above the oil level and parallel to the oil surface. An extension pipe having a ventilating filter therein, is placed on the bore line on the side of the roller mount.
