Railway ballast crusher with rotary thresher - has angled blades suspended from stirrups displaceable radially on rotor to adjust angular position of blades

摘要

The crusher has a rotor consisting of a tubular piece with a large diameter. The rotor is fitted with a number of pairs of angled threshers (2) with elbows, causing them to open out away from each other. The threshers are supported onto hooks (3) which are supported in the bearing blocks (8) on one side and the a adjustable bearings (5) on the other. The angular position of the blades may be varied radially by mounting the bearing blocks into slots on the rotor. The rotor slots are part of a separate bolted assembly.
