Re: New invention.
Even if it works, this is not quite the 'big deal' that they seem to make it out to be. The 'standard' process of grinding something up uses big rollers or 'gears' that smash things between them. These wear out and have to be replaced, yes. But this thing has got to have 'wear and tear' as well. The stuff you dump into it is banging against the insides. What happens when it finally pounds a hole in itself? Replace the whole machine? It might be a nifty innovation but this does not automatically make it commercially viable.
