You can probably blow it in just fine. The problem is really getting bulk materials out of hoppers. A whole world of research and engineering unto itself. Start with a simple question like: what kind of model do you use with bulk materials. Obviously it's not a liquid, but as a solid it has tons of weird properties- No tensile strength at all. Strength depends on history of compaction. The list goes on...
