Miners used mechanical crushing and grinding machines to break up ores for further processing. Early miners used Mexican arrastras or stamp mills, which reached their peak in the late nineteenth century, to crush ores into sand-size particles. Before going to stamp mills, ores often went through rock crushers, which were like nutcrackers.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

What is Quartzite? Quartzite is a nonfoliated metamorphic rock composed almost entirely of quartz.It forms when a quartz-rich sandstone is altered by the heat, pressure, and chemical activity of metamorphism.. Metamorphism recrystallizes the sand grains and the silica cement that binds them together. The result is a network of interlocking quartz grains of incredible strength.
