Figure 2 Ball mill at Boliden Aitik copper mine. An example of an industry-standard comminution circuit providing high throughputs can be seen in (Fig. 3). This circuit, however, has a high, specific energy consumption per ton of ore processed, driven primarily by the low efficiency of the ball mills and the need to use steel media for grinding.

Will's Mini-mill Biobug

After using my mill manually for a few tasks, I began to despise the play in the ACME ball screws. I bit the bullet and converted my mill to use ballscrews like Hoss did. I ordered three lengths of ball screws and three ballnuts from homeshopcnc.
