Jaw Crusher Rotation Direction? (3 replies)

6 years ago

I have an old Union Iron Works jaw crusher that we're trying to get back into service. It came with a 3 phase 15 HP electric motor and we're not sure which direction the crusher flywheel should rotate. Looking at the crusher from the side, with the jaws on the right and the motor on the left, should the crusher flywheel rotate clockwise or counterclockwise? I've attached a photo.

Thank you

The action should be pulling the rock downwards, so that in the bottom grabs and pulls while the top then crushes. For a simplified picture see the bottom of this:
