How grinding mill design changed over the last 30 years
The design process has changed dramatically with computers though. A typical FEA of a grinding mill that would take about 3 hours on a minicomputer in the late 80's takes about 3 minutes on a laptop computer today. This allows the analyst to add more detail to the models (increased accuracy) and check multiple options to optimize design …
