Fuzzy logic for load control of the grinding mill ...

The nonlinearity of the load characteristics for the grinding mill results from random variation of the parameters such as the grain diameters of the materials. It's not satisfied with the convertional PID control, hence a fuzzy controller with on-time learning ability is proposed. The experiments show the controller has good adaptability and steady-state accuracy.

Milling vs. Grinding - obsidianmfg

Grinding says: Of course, everybody should try to avoid thin-walled sections, but there are times when design characteristics will not allow it. The rigidity of the grinder, using the minimum feed available, can help adapt grinding technique to the part. It is unusual to have to consider vibration of the thin sections.
