Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with ...

The stamp mill was the big gold machine of its day. By 1850 in California all of the rivers and streams had been picked clean of placer gold. It didn't take long for miners to follow the gold deep into the Sierra's steep valleys to snow white quartz outcroppings. They soon realized the gold trapped within these veins could produce thousands ...

Stamps were the most common way to crush ore for many decades, but by the first few decades of the 1900s the ball mill started replacing stamps. By the 1930s, many stamp mills were retrofitted with ball crushers, replacing the stamps that were originally used. While stamp mills throughout the west were similar in how they crushed the ore, the ...
