Centrifugal sieving for the size separation of lunar regolith in microgravity

Myles Martinez, John Fruit, Christopher Dreyer, Otis Walton & Ned Riedel
For any microgravity environment traditional sieving methods used on earth can fail or be less effective for smaller size particles. Previously a device was designed and built that uses centrifugal force created by a spinning screen to push material through and a spinning helical auger to create shear flow to sieve independent of gravity. Power consumption of the motors was monitored via two ammeters and blinding of the screen was monitored regularly with a camera...
