3 Types of Grinding Media for Ball Mills

Dec 04, 2019 · When the ball load exceeds 40%, the ball is pouring; When it reaches 50%, the surface of the ball is just on the diameter line of the cylinder, so it is easy to pour which is exactly needed for ball mill production. According to the actual results, when the charging is 40%, the output is the highest.
