- the bracing element is formed by a screw or threaded bolt which can be screwed at one end into a threaded element in an end face of a lining element, while the other end bears against the end face of the adjacent lining element, such screwed fasteners are used.
- threaded bolt not only comparatively easily adjustable, but can also be adjusted with simple tools in their effective length by being screwed into a corresponding recess with a thread on the end face of a Auaemployedsijns or in a recess is provided with a threaded element.
- the threaded element is formed by a non-rotatably received in a recess in the face nut, facing away from the end face of the lining element, the recess for receiving the nut by a concentric bore or a blind hole is continued whose (the) inside width exceeds the outer dimensions of the screw or threaded bolt.
- a plurality of Verspannettin in particular screw or threaded bolt, is provided side by side on the end face of a lining element.
- the bracing elements are arranged between radially circumferentially adjacent end faces of lining elements, so that a secure hold of given to be removed or to be replaced lining elements adjacent lining elements , Furthermore, it is to be assumed that, in particular after a prolonged use, filling any existing intermediate spaces between further lining elements with material to be treated in the mill assists the bracing effect between permanent lining elements and thus secure retention of the lining elements.
- Verspannelement is preferably provided that at least one Verspannelement between adjacent lining elements over the entire circumference in the radial direction at least one position, in particular substantially equally distributed is, resulting in a minimum number of Verspannettin or
- the wear lining according to the invention in the wear lining additionally at least partially between adjacent lining elements to the end faces of the lining elements substantially complementary shaped spacer and / or lining sheets are provided, with such additional spacer and / or lining sheets not only possibly existing free spaces between adjacent lining elements and in particular between the end faces can be filled, but also an adaptation to different dimensions of the inner diameter of the mill when using substantially a constant size having lining elements succeed.
- the lining elements are formed at their end faces with preferably continuous, groove-shaped recesses in which complementary projections or Elevations of intermediate spacer and / or lining plates can be accommodated, as corresponds to a further preferred embodiment of the wear lining according to the invention.
- the recesses on the end faces of the lining elements have a cambered or substantially circular arc-shaped outer contour, wherein the radius of a projection is preferably less than the radius of the associated recess.
- the projections and recesses are arranged at a distance from the mill shell facing outer surface of the lining elements, which is 2 to 30%, preferably at least 3 to 15%, of the total height of the end faces of the lining elements This portion is usually largely protected from wear, so that a secure mounting of adjacent lining elements can be achieved.
- clamping elements are provided directly between all the lining elements or their end faces, but it is possible by suitable choice of the clamping elements and optionally between adjacent lining elements distance and / or lining sheets possible, Verspannetti for example only to provide each between the next but one lining elements.
- an adapter plate which is formed with recesses or openings for receiving the free ends of the threaded bolt and at its second side surfaces on the End face of an adjacent lining element is applied, whereby by appropriate design such adapter plates, which also additionally assume the function of optionally provided in the interstices of other lining elements spacer and / or lining plates, care can be taken that at least one of the end faces of the lining elements in each case substantially ident can be formed independently of the provision of a bracing element, since by correspondingly complementary shaping of the adapter surface a secure interaction with the end face This lining element is possible.
- an adapter plate can be formed with corresponding recesses for receiving the Verspannide or for example the free ends of screw or threaded bolt. If no adapter plates are used in the region of the provision of bracing elements, the end faces of the respective lining elements can be formed with recesses or recesses for receiving free ends of bracing elements.
- the inventive provision of Verspannettin between at least some lining elements can further, as already indicated above, find the Aus GmbH with a small number of retaining strips, while between the retaining strips further lining elements braced against each other and held together, in this context in an It is preferably proposed in a known manner that the wear lining is formed from lining elements fixed to the holding strip (s) and in the direction of rotation of the grinding drum between the holding strip (s) of further lining elements supporting one another against a circle segment.
- the at least one retaining strip has a projecting from the mill shell, widening head for fixing the lining elements, which head is substantially trapezoidal, in particular dovetail-shaped, is formed, wherein the shorter of the two parallel sides on Mill shell rests.
- a simple sliding of lining elements on the retaining strips without the need for additional, additional fixing is achieved in that the fixable to the retaining strips lining elements on their mill shell facing sides to the shape of the retaining strip complementary recesses, as corresponds to another preferred embodiment of the invention .
- the retaining strip (s) arranged on the mill shell substantially in the longitudinal direction of the drum is (are) formed in several parts in the axial direction, at least in the circumferential direction of the grinding drum two, in particular four, retaining strips are arranged on the mill shell, moreover, by providing a plurality of retaining strips and ball mills can be retrofitted or equipped with a comparatively large diameter and essentially with a uniform shape of the lining elements Aus GmbH can be found as between faces adjacent lining elements are at least partially provided according to the invention proposed Verspannetti.
- mill shell 2 is provided with two retaining strips 3, the retaining strips having a widening head which is substantially trapezoidal or dovetail-shaped, the shorter of the two parallel sides being provided on the mill shell 2.
- retaining strips 3 are directly lining elements 4 can be fixed, in particular pushed, which have complementary to the shape of the retaining strips 3 recesses 5 formed, so that by simply pushing a lining element 4 this is fixed to a retaining strip 3.
- a lining element is again denoted by 4, which can be secured via a recess 5 on a retaining strip (not shown in detail in FIG. 2).
- the adjoining, not formed with a recess lining elements are again generally denoted by 6.
- a lining or spacer plate 7 is provided, while on the side facing away from the spacer and / or lining sheet the lining element 6 is braced with an adjacent lining element via a bracing element, which is designated schematically in Fig. 2 with 8, wherein such a bracing element is even more clearly visible in the following figures.
- a bracing element which is designated schematically in Fig. 2 with 8, wherein such a bracing element is even more clearly visible in the following figures.
- two juxtaposed lining elements 6 are clamped together by means of a bracing element 8, while spacing and / or lining plates 7 are provided between the adjoining lining elements, since a sufficient bracing force can be applied by the bracing elements 8.
- the different arrangement and the number of lining elements to be clamped directly together or the number of lining elements between which the arrangement of a spacing and / or lining plate 7 is sufficient depends in particular on the geometry of the mill shell 2 to be lined and the dimensions of the insert Lining elements 4 and 6 from. For example, with four substantially equally distributed positions for arranging the bracing elements 8 over the entire circumference, the problem can be found.
