· Stamp mills were large and cumbersome tools, but they were an absolute necessity for the hard rock miners. While it was possible to crush ores using more rudimentary methods, the mechanized process used with stamp mills meant that large quantities of rock could be pulverized. Stamp mills were effective machines for mining gold in the early
Rod mill - A rotating steel cylinder that uses steel rods as a means of grinding ore. Room-and-pillar mining - A method of mining flat-lying ore deposits in which the mined-out area, or rooms, are separated by pillars of approximately the same size.
For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.
