REGWHDING MACHINERY By S. V. Trent (March 31, 1904) I have read with much interest the statement of tests made by Martin Schwerin in the Engineering and Mining Journal of March 10. Having given a good deal of study and observation to the matter of crushing and pulverizing machinery, I am naturally interested in a subject of this kind, especially as I happen to be familiar with the operations at Anaconda. While I believe Mr. Schwerin's conclusions are in the main sound and correct, I believe his generalizations in regard to Chilean mills, Huntington mills, rolls, etc., are very far from final, and that he himself will be willing to admit this, after consideration of certain features that he entirely overlooks in the article in question. Furthermore, there is one all-important feature developed by the earlier tests at Anaconda of which he makes absolutely no mention. I refer to the fact that in the comparison between the Monadnock mills that were used in the old plant of the upper works, as compared with the performance of crushing rolls, Gates and others, doing similar work, it was found that the final tailings from the tables taking their feed from the Monadnock mills showed a much lower residue of copper, ranging from 0.5 to 0.6 per cent. On the other hand, the tailings from tables taking their feed from the crushing rolls of different makes showed an average copper content varying between 0.85 and 0.95. This was indeed a revelation, and could only be accounted for on the supposition of a more favorable form of grinding by the mills, a...
