Impact machines have two main advantages over jaw crushers: they're faster and more efficient at reducing the size of rock fragments, and they don't require as much power. They work by impact rather than compression, which means that the crushing action is caused by a heavy object striking the stone repeatedly with great force.
3. From 'artisanal' to 'small-scale' gold mining in Kamituga. Prior to 2011, all gold in Kamituga was crushed manually by workers, mainly women known as mamans twangaises, who were busy pounding the pieces of stone 5 from the pits in a mortar or on a large stone. This in turn required significant time and money to transport the stone from …
