Another essential piece of equipment used in hard rock gold mining is impact crushers. These machines use high-speed impact forces to crush rocks against anvils or breaker plates. They are particularly useful for reducing large chunks into smaller, more manageable sizes. Grinding mills are also vital in the hard rock gold mining process.
