How Much Crushed Stone Do You Need? A SureFire Formula

Crushed stone is produced by passing stones through a crushing machine at a quarry. Various types of stone are used in this operation, such as granite and limestone. At the bottom of the crushing machine lies a screen that traps the the crushed stone product (the finer material that passes through the screen is also kept and sold as stone dust).
