The ratio of the trunnion thickness to trunnion diameter in a mill of 2,134 m diameter is almost twice that of a mill of 5,8 m diameter, a ratio (T/D) of 0,116 to 0,069 for the large mill. However the design stress levels at the trunnion/head transition in the case of the large mill are almost 250% of those in the small mill.
