Clamping arrangement for a crushing cup

摘要

The present invention concerns small and medium-large conical crushers and especially fastening arrangements for crushing cups. A fastening arrangement for a crushing cup comprises a stationary support ring 3 adapted to and engaging with the cup 2 via threads 1, a cylindrical bushing 4 mounted on the top side 5 of the support ring 3, and also a flange 6 arranged on top of the bushing 4 and supporting hydraulic jacks 7 to create a clamping axial pressure in the threads between the cup 2 and the support ring 3. The flange 6 is adapted to and engages with the cup 2 via threads 15 and is loaded to prevent rotation about the support ring 3, and piston rods 9 for the hydraulic jacks 7 rest against the cylindrical bushing 4.
