Ball vs Rod vs Roll Mills Gold Refining
Jun 11, 2019· The rods and ore were loaded into the mill through a sealed bolton front plate for grinding, and the front down tilting stand allowed for easy rod removal and clean up. With the mix of rods, and the mill running over night, we got a dry grind of < 200 mesh on about 20 Kgs. of minus ¼" ore. That''s a 86 times reduction.
