    human powered sand mixer mechanism?

    Thanks berkshire a very interesting idea. I think this is the most feasible mechanism I have come across thus far. I would probably alter the implementation to use a hand crank instead (and gear it up as necessary) but I think that it could definitely work. Much appreciated. Sincerely, T.B.

    human powered sand mixer mechanism?

    Hi Berkshire, Yes, please let me specify. the conveyance will only be happening to the next stage of the process. We are still speaking conceptually at this point, but I would be surprised if it was more than 1.0m, and I imagine could be as little as 200mm T.B.

    human powered sand mixer mechanism?

    Hi B.E. Yes, I have looked at them, and think they show promise. Further to that, I have found that the ribbon blender is quite interesting too (although it does not convey as well). The ribbon blender I found (see link) has both clockwise and anti-clockwise ribbons, which really help a...

    human powered sand mixer mechanism?

    Hi CompositePro, The sand is used for odor control, preliminary filtration and to help prelim separation of the solid and liquid streams. it is then used upstream in the onsite disinfection process. unfortunately, at this point, I cannot go into detail about how that happens. So yes, ideally...

    human powered sand mixer mechanism?

    Hi Mike, I have actually tried a meat grinder. Unfortunately, wet sand clogs it up and greatly increases effort almost immediately. Beyond that it doesn't appear to be a very good mixer.

    human powered sand mixer mechanism?

    Hello All, I'm looking for some tips on how to design and construct a human operated sand mixing system that can be operated by a variety of different users (ie. minimum input power). The mechanism is meant to be part of an experimental off-grid toilet system. We hope to capture the solid and...
