Making litter into usable clay [Archive] AlloyAvenue ...
Montimorillimite ( same thing in kitty litter) has a hardness of about a 1 on mohs scale so the blender is able to break it up pretty easy, just takes time . Right now though I am trying to build a bulk ball mill for grinding the clay using a bad propane water heater, I figure that I need to run the barrel at about 75 rpm and I will use granite balast rock from the rail road tracks for my grinding medium.
