Grinding Balls & Rods
Grinding Balls. Steel balls ranging from ¾ to 5 in. in diameter are used. Rods range from 1½ to 4 in. in diameter and should be 3 to 4 in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4- or 5-in. balls are more commonly used for ball-mill grinding.

How to correctly grind Tungsten Electrode for TIG Welding
If possible, use the dedicated grinding machines. Using the grinder for other applications can damage the grinding disc. Grind the tungsten to an angle of about 60 degrees for longer life. Use a tungsten grinding clamp. This will gives a tight grip on the rod while grinding. It will also be a safe work practice.

Operating and Troubleshooting a Grinding Circuit
A ball mill operates more with the grinding surface action of the balls than the impact form of grinding that the rod mill uses. Taking this into account you can see that if the rod mill doesn't reduce the ore to a size that the ball mill can reduce quickly, the circuit load will climb until its volume is greater than can be handled.
