Cool Stuff Being Made: How Rock Is Quarried

quarry.jpg“Manufacturing” is defined as the process of making a raw material into a finished product, especially by means of a large-scale industrial operation. Maybe not everyone would immediately think of the quarrying of granite as manufacturing, but it is.

This week, our friends from South Carlina Educational TV travel to a 429-acre quarry to see how granite is quarried and processed. Basically they take big rocks and make them into smaller rocks — first by blasting and then through the use of a drop ball, a rock hammer and the always-reliable gyratory crusher. In fact, Winnsboro blue granite is the state stone of South Carolina — but then, you already knew that, didn’t you? Once you watch this video and see what goes into this process, you’ll never take it for granite again….Sorry, couldn’t resist.
