Analysis of a Stamp Mill of Mexico’s Antique Mines
The typical Stamp Mill used in the Mexican mines is shown in Fig. 3. The mules (blood engines) pulled the arms (k) and revolved the vertical axel (i) and face gear, which rotated pinion (g) and incremented the angular speed of the camshaft (2). The cams (f) were shifted to produce a continuous impact on the ore.The Michigan Mine used one of the stamp heads at the Mass Mill to process rock (1902–1906), while it constructed what became a non-operational Mill (Michigan Mill) north of the Mass Mill (1906). The Mass Mill operated until after WWI, when prices for copper drastically declined. The Mill closed down in 1919 (Fig. 3) and was Copper-rich “Halo” off Lake Superior’s Keweenaw Peninsula
