Mars Mill/Miller

The initial concept was centered around a belt-driven bucket, but space constraints necessitated a design overhaul. Upon adding the finishing touches, I realized it resembled a water mill, prompting me to dub it Mars Mill or Miller. The external ridges slope at 45 degrees to maximize surface area as they rotate. This clever design also features a grater situated at the bottom of each ridge channel, enabling regolith to flow effortlessly while keeping rocks and other unwanted detritus at bay.
