The processing plant further includes at least one damper to be arranged in between the bottom and upper support surfaces which damper includes a first counter surface for the bottom support surface and a second counter surface for the upper support surface and an elastic material layer between the counter surfaces and preferably a slide joint between the first counter surface and the bottom or upper support surface. A method for damping a jaw crusher in a mineral material processing plant is also disclosed. ## Claims ### Claim 1 A mineral material processing plant comprising: a processing plant frame having at least two upper support surfaces at a distance from each other in longitudinal direction of the processing plant; and a jaw crusher comprising a crusher body having at least two bottom support surfaces at a longitudinal distance from each other, wherein the processing plant further comprises at least one first damper or second damper to be arranged in between the bottom and upper support surfaces which damper comprises a bottom support surface first counterpart and a upper support surface second counterpart and an elastic material layer between said counterparts which elastic material layer is fixed non-detachable to the first counterpart and to the second counterpart ### Claim 2 (depends on 1) The processing plant according to claim 1, wherein the second damper comprises a slide joint between the first counterpart and the second bottom or upper support surface, and a bolt or welding joint between the second counterpart and the upper or bottom support surface. ### Claim 3 (depends on 1) The processing plant according to claim 1, wherein the first damper comprises a bolt or welding joint between the first counterpart and the second bottom or upper support surface, and between the second counterpart and the upper or bottom support surface. ### Claim 4 (depends on 1) The processing plant according to claim 1, wherein the elastic material layer of the first and second dampers is of rubber which preferably is vulcanized to the first counterpart of steel and the second counterpart of steel. ### Claim 5 (depends on 1) The processing plant according to claim 1, wherein a side support is arranged to the second damper or to the frame of the processing plant or to the body of the crusher for positioning the frame/body relative to the second damper. ### Claim 6 (depends on 4) The processing plant according to claim 4, wherein the hardness of rubber used in the elastic material layer is 40 to 80 ShA, preferably 60 ShA. ### Claim 7 A method for damping a jaw crusher in a mineral material processing plant which comprises a processing plant frame having at least two upper support surfaces at a distance from each other in longitudinal direction of the processing plant, and a jaw crusher comprising a crusher body having at least two bottom support surfaces at a longitudinal distance from each other, characterized by arranging at least one first damper or second damper in between the bottom support surface and the upper support surface which damper comprises a bottom support surface first counterpart and a upper support surface second counterpart and an elastic material layer between said counterparts which elastic material layer is fixed non-detachable to the first counterpart and to the second counterpart. ### Claim 8 (depends on 7) The method according to claim 7, wherein the method comprising arranging shearing constant in side direction substantially equal as in machine direction. ### Claim 9 (depends on 7) The method according to claim 7, wherein the method comprising arranging substantially one natural frequency for the first and second dampers.
