Ball Mill with Classifying System. Ball mill is also known as rotary ball mill. Inside the ball mill, there are many different sizes of balls, which is called ball media. And when the ball mill rotates, the ball media and feed limestone inside the ball mill will collide and crush so as to make fine and ultra fine calcium carbonate powder.

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.
