... of the attrition mill wear plates In Fig. 2 , a new, unused grinding plate (left) is a 230 mm (9 in.) diameter and 25 mm (1 in.) thick disk of gray cast iron with a hardness of 338 HV and 0.1 mm (0.004 in.) graphite flakes, which are an excellent absorber of vibrations during mineral grinding. Radiating...

It also included FEA (thermal gradients, nonlinear material behavior, residual stress, changes in wall thickness during the formation of U-bends, and TSP distortions near the ruptured tube) of three-dimensional solid models of the U-tubes. The conclusion was that distortion of the TSPs and resulting...

The swing arm stub is constructed of both tubes and plates approximately 3.2 mm (0.125 in.) thick, while the plates that locate the rear axle are 4.8 mm (0.188 in.) thick. Cracks in the cargo box frame occurred in several locations as shown in Fig. 2 . At one...

Corrosion fatigue and general corrosion also contributed to hull plate perforation. Although it is probable that more lamellar tears exist near...
