A reliable, inexpensive option for the plates that function as wear parts and are mounted on an inner face of a casting wall of a stator. To achieve this the plates are designed as cast parts and are fixed to the inner face of the casting wall from an exterior of the stator. The plates are fixed by fixing bolts, which are screwed into the plates through the casting wall from the exterior. The plates have transverse threaded bores that correspond to the bolts. Respective spacer rings are pushed onto the fixing bolts secured by wedge-shaped cotters in both a positive and non-positive fit, and the wedge-shaped cotter pressing on the spacer rings that lie against the outer face of the casting wall. This invention is extremely economical and improves the operational safety in comparison to known options.

The invention claimed is: 1. A stator (1) of an impact crusher for separation of compound materials with an outer face (4) of the casing wall and an inner face (3) of the casing wall, which is plated with a plurality of plates (10) with ribs (13, 17), wherein the plates are designed as wear parts and are attached replaceably, the stator comprising: the plates being metal cast plates having at least one transverse threaded bore (18) casted within the metal cast plates, and the outer casing wall (4) of the stator having passages through which fixing bolts (20) with threads fitting into the threaded bore of the plates can be passed through and are visible from an outside of the stator, wherein the fixing bolts (20) comprise a slotted hole (23) disposed on the outside of the stator and through which a wedge-shaped cotter (25) is insertable. 2. The stator according to claim 1, wherein the plates (10) comprise a substantially planar lower base (11) and an upper work face (12), the work face is formed by parallel ribs, the first rib walls (14) of which are each extending perpendicular to the base (11) and axially parallel inwards to a stator center axis in a mounted condition, while the second rib walls (15) extend inclined with respect to the base. 3. The stator according to claim 2, wherein the bases (11) of the plates (10) comprise supporting strips (16) which project slightly from the base. 4. The stator according to claim 2, wherein perpendicular to a longitudinal direction of the crusher ribs (13) reinforcement ribs (17) are extending between the crusher ribs. 5. The stator according to claim 1, wherein the plates are attached on the inner face (3) of the casing wall with at least an intermediate rubber mat (30) therebetween. 6. The stator according to claim 1, wherein over the fixing bolt (20) a spacer ring (24) is pushed which rests on the outer face (4) of the casing wall and the wedge-shaped cotter (25) is pressing on the spacer ring (24). 7. The stator according to claim 6, wherein both the spacer ring (24) and the wedge-shaped cotter (25) each have a transverse bore (26, 27) through which a connection element (28) is inserted. 8. The stator according to claim 1, wherein between the plates (10) and the inner face (3) of the casing wall of the stator a rubber-elastic mat (30) is placed. 9. The stator according to claim 8, wherein the mat (30) corresponds to a width and a height of a plate (10) or to integer multiples of the width and the height. 10. The stator according to claim 8, wherein the mat (30) corresponds to the width of the plate and the height of the inner face (3) of the casing wall. 11. The stator according to claim 1, wherein the stator comprises a polygonal inner cross section, a width of an edge of the polygon is fitted to a width of the plate, and the plate (10) can rest planar, indirectly or directly, on the inner face of the stator. 12. The stator according to claim 1, wherein a plate (10) for encasement of the stator (1) of the impact crusher is for separation of compound materials, with the outer face (4) of the casing wall and the inner face (3) of the casing wall, which is plated with a plurality of plates (10) with ribs (13, 17), wherein the plates designed as wear parts are attached replaceable, and the plates are metal cast plates having at least one transverse threaded bore (18). 13. A stator of an impact crusher for separation of compound materials, comprising: a casing wall having an outer face and an inner face, a plurality of metal cast plates designed as wear parts and replaceably attached on the inner face, each of the plurality of plates including crusher ribs extending in a longitudinal direction and reinforcement ribs extending between the crusher rib and perpendicular to the longitudinal direction; threaded bores cast within each of the metal cast plates on a side facing the inner face; passages extending through the casing wall of the stator and each aligned with one of the threaded bores; fixing bolts including threads fitting into the threaded bores of the plates, the fixing bolts each having a portion that extends through one of the passages, is visible from an outside of the stator, and includes a slotted hole disposed on the outside of the stator; a plurality of wedge-shaped cotters each insertable within the slotted hole of one of the fixing bolts.
