Rock and Roll: a simple ball mill

In order to make my first batch of fireballs I needed some charcoal fines or dust. I charred some switchgrass and leaves to start with. That would be easy to reduce, but was unsure how to go about this task at hand. Having already removed the paddles from the cement mixer, I got the bright idea to place the switchgrass and leave char in the cement mixer plus one large rock, see picture #1. So I gave it a try, not knowing that there is such a device as a ball mill. I learned fast that a lid was in order! Dust cloud anyone? This worked well for the charred switchgrass.

This modular stove is built from used metal containers.

It has a center fire burner module, a sunken 8-liter pot module, and an insulated/ chip drying top cap.
The burner and is made from an institutional food can. It takes all the ware and stress from the fire protecting the rest of the stove body.They are easy to build and can act as fuel cartridges to store fuel for quick and easy use.
The burner module, under development, adds secondary combustion air to the top of the burner.
