### A Case Study of a Pull Rod Failure in ATOX Raw Grinding Mill

ATOX raw grinding mill [1] uses the pressure and the shear generated between the roller and the rotating table to crush and grind the raw material. Feed material is directed onto the grinding table by feed chute. The rotation of the grinding table accelerates the material towards the grinding tracks and passes it into the rollers.
