I'm working as an intern trying to automate this grinder system. I would like to find the minimum torque needed for the grinder motor.(adsbygoogle = window.adsbygoogle || []).push({});

The grinder motors we currently use have:

1.25 HP

RPM between 8,000-11,000

13 amps

120 volt AC

The grinded surface has a:

Coefficient of Friction: 0.75

We grind the surface with braided cup grinders like the one seen here:
