Is It Possible To Grind Stucco?

Grinding stucco produces a huge amount of dust and flying particles so be sure you have a respirator, eye/face protection, gloves and any other protective equipment you may need. A fan can also help with the dust. Keep a good grip on your angle grinder, as grinding stucco can make the grinder kick pretty good and possible fly out of your hands.

Centerless Grinding - an overview | ScienceDirect Topics

In centerless grinding, the workpiece is held between two grinding wheels, rotating in the same direction at different speeds.One grinding wheel is on a fixed axis and rotates so that the force applied to the workpiece is directed downward. This wheel usually performs the grinding action by having a higher linear speed than the workpiece at the point of contact.
