  • 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.
