Tube mill

Me firing concerns a tube mill, consisting of a cylindrical housing, which is provided with an exchangeable inner armor, has a filling of spherical, zy ^: i ier- or dust-shaped grinding media and with axially concentric and externally arranged at a distance from the mill housing roller conveyors on tires ( _e. B. e. commercial vehicle tires) is supported, which in turn are driven by suitable means _e

MülT.en of this type are mainly used in 4 "stone and earth industry" used. They differ from the conventional tube mills in that, instead of the drive, the very expensive neck-ring bearings the drive can take place via commercially available gearboxes and vehicle tires. In the known mills of this type, the runways are via intermediate webs with the cylinder jacket of the mill housing, for example by means of a tail connected. The tangential forces caused by the drive are thereby transferred to the cylinder jacket and the armor via the intermediate webs of the runways transfer. The consequences of this are constant stresses on the intermediate webs of the taxiways through tensile, bending and shear forces, i.e. the destruction of the Can lead connection between the intermediate webs and the cylinder jacket. In addition, the adaptation of the intermediate saw to the runways and the Cylinder jacket is a very precise and therefore expensive workshop work.

The task of the innovation is to remove the hinge backs described above zu ve-Tneiti ^ n »This task is achieved in that the taxiways through appropriate deepest icmn ^ p means are connected with the inner armor, whereby

the cylinder jacket in the area dex- i / u ± vhfühi.arig "Sr Sefestiguxigsiiiittel Offiiuj; - gene has, in particular in the longitudinal direction of the cylinder jacket considerably Larger than required for the fasteners to pass through. In such an embodiment, in which the cylinder jacket expand freely can, the cylinder jacket remains unaffected by forces that are caused by the type of drive, In addition, possible manufacturing inaccuracies at the intermediate webs by installing an elastic intermediate layer that separates the roller tracks from the cylinder jacket of the mill housing will.

The novelty is in Jen's drawings and in more detail of her relevant description explained.

FIG. 2 shows the details of point "A" in FIG. 1 on a larger scale.

The housing of the tube mill lies with its cylinder jacket 10 on the only partially shown tires 1 and is set in rotation by this by a drive, not shown. The mill housing is on the front sides completed by end walls 11, in which the openings 12 BEZW for the supply. Discharge de?

Depending on the type of goods to be married into the interior of the housing spherical, cylindrical or rod-shaped grinding media brought in freely movable "

The roller tracks 20 are arranged near the ends of the cylinder jacket 10. she For manufacturing reasons, they preferably consist of at least two Ring halves 21. Ai 'the ring halves are angle irons 22 in the circumferential direction welded, one flange of which runs parallel to the cylinder jacket 10. An intermediate layer 50 is made between the cylinder jacket and the angle iron flange

The fastening of the runways 20 is carried out by threaded bolts. I) Ip threaded bolts engage with their conical head 41 in the conical part 32 of the bores 31 in the inner lance η inr 30. On the opposite side, the Vlannch uen Wlnkeleisenf? 22, are the nuts 43 and ^ i ^ I'mtprlep-nnheiben A ₁ ? arranged. If necessary, the runway can be orzopened with synthetic or natural rubber vulcanized on the outside guard.

In the cylinder jacket 10 are in the penetration area of the threaded bolts the openings 13 are provided, at least in the longitudinal direction of the cylinder jacket 10 are considerably larger than the diameter of the threaded bolt. Accordingly, the cylinder jacket 10 can expand freely.

The innovation is not limited to the illustrated embodiment. Instead of the angle iron 22, other profiles can also be used, with the roller tracks 20 optionally being part of these profiles. Likewise, the connection between runway 20 and inner armor> 0 can be made by other suitable means, for example rivets.

Schutzan ^ nruc. Tube mill, consisting of a cylindrical housing with a exchangeable inner armor is provided, a filling of spherical, has cylindrical or sta ^ shaped grinding media and with axially concentric and outside at a distance from the mill housing arranged runways on tires {e.g. commercially available vehicle tires) that are in turn driven by calibrated means, characterized in that that the roller tracks (20) are supported by an elastic intermediate layer (5 from the cylinder jacket (10) of the mill housing and separated by suitable Fastening means (40-43) are connected to the inner armor (30), wherein the cylinder jacket (10) in the area of the penetration of the fastening means (40) has openings (13), in particular in the longitudinal direction direction of the cylinder jacket are considerably larger, s for the passage the fastening means is required.
