    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.

    The purpose of the invention is to improve the accuracy of measuring the oil level. This goal is achieved by the fact that in a grinding roller for a roller mill, there is a shaft mounted in the support element with under the hips, located in the oil bath cavity, on which a hub is installed, provided with a grinding rim provided with a central through channel, an air gate and a chamber, at the same time, the central chamber of the chamber with the oil bath and the cavity of the air seal from the side of the supporting element communicate with the central squiche of the shaft; otorrhea central channel is connected to the gate vozdushnog cavity and a cavity with an oil chamber above the oil bath level in the latter. In the drawing e schematically shows one of the grinding rolls, which is equipped with a roll mill, a section. The chopping roller 1 is rotatably mounted in an annular bowl 2 resting on a support (not shown) and driven by rotation by means of a motor. Each chopping roller 1 is attached to the support element 3 of the roll and is set at an angle of about 15 to the vertical. The support element 3 of the roll carries a shaft on which a grinding roller 2 is mounted on the bearings for rotation. From the guide frame, which acts on the support element 3 of the roller, force is transmitted to the grinding roller 1 for grinding. The chopping roller consists of rim 5 made of bleached cast iron and a hub. 6. The roll rim has a channel profile and is put on the seating surface of the hub. To prevent axial displacement, a stop ring 7 connected to the roll hub 6 is used, which is adjacent to the side surface of the roll rim. Spinning prevents c by fitting the fittings 8 into the corresponding grooves of the side surfaces of the rim. The roll hub is mounted on the shaft t with the help of two bearings 9 and 10 rolling. When this bearing 9 is fixed relative to the shaft, and the BEARING 10 - floating. Bearings 9 and 10 are lubricated by immersion in oil. The oil on the bath is located in the space 11 formed between the hub 6 of the roll and the shaft 4 and in the intermediate space 12 between the hub and the cap 13 isolating it relative to the inside of the mill. The oil level in the drawing is indicated by a line. The shaft has a central through channel 15 through which a probe passes through the inside of the intermediate space 12 to the oil pan. The probe can consist of a thermoelement whose metal sheath is electrically insulated relative to the center channel 15. The sheath of the probe and the center channel form opposite surfaces of the condenser. its capacity when oil penetrates between these surfaces. For remote monitoring, measuring lines 17, which are output from the mill, are connected to the measuring probe 16. The support element 3 of the roll is provided with a connecting pipe 18 for supplying compressed air to the annular space 19 inside the supporting element 3 and through the channel 20 into the cavity of the air seal 21 above the cover 22 at the rear shaft end. Through the central channel 15, the cavity of the air gap 21 is connected to the intermediate space 12 The central channel 15 is connected via an additional channel 23 for discharging air passing obliquely through the shaft t to the cavity 21 under the cover 22. The extension 2 is connected to the additional channel 23 with a filter 2. 5 for supplied air. From facing the inside of the mill end of the shaft through the latter passes the second additional channel 26 of exhaust air. This second additional channel 26 passes above the oil level and is parallel to it and connects the intermediate space 12 with the central channel 15. The diameter of the second additional channel is 1/4 smaller than the diameter of the central channel 15. Due to the interplay of both additional channels 23 and 26 inside the chopping roll set
