[permaculture] DIY Rock dust

Reading about the additions of rock dusts from quarries, I'm looking at 
this land.
Its dust and fine mineral breakdown was carried off by former farmers. 
The current soil has clay and rocks 3-inch to boulder for a few feet 
until bedrock. One option I have is trading stones naturally shaped for 
building with a quarry in exchange for their dust created from 
reshaping. But I'm looking at other possibilities. Anyone have resources 
for pulverizing stone on a small scale?
