Have built a hammer mill that will pulverize sod in place on the ground. Would like to find a way to pick up the pulverized material and separate out the grass, rocks and other debris and deposit the soil back on the ground where it was picked up. I have seen vacuum trucks for removing gravel from ballasted roofs, that have cyclonic type collectors where the gravel drops out the bottom of the collector into a truck or roll-off container.
So... with a larger vacuum device - say an 8 hp. lawn vacuum, and a scaled up version of the Thien unit, would it be possible to vacuum up the pulverized sod at the hammermill and have it drop out the bottom of the collector bin onto a series of vibrating sieves to separate it, collect the waste material and allow the dirt to fall back through the sieve to the ground?
