the ball mill | Gold Refining & Metal Extraction Forum

There's about as much wear on the ball mill as there is on the material being processed. Lifters, too, are not in anyone's best interest. Running the correct speed is always desirable, so the balls drop and crush---which is what ball mills are intended to do. My ball mill was about 18" in diameter and was fed ½"- material.
