Multiply these together to give the volume of the area. Divide this cubic inch volume by 46,656 for the volume in cubic yards, or the cubic cm value by 1,000,000 to give the volume in cubic meters. You can use an online calculator to assist with this, which will give the amount of stone dust you need in cubic meters and metric tons.

Crusher sand is produced from solid blue granite rock that is drilled and blasted to loosen it up and fragment it into a manageable size. The layer of material mined is +25m below the surface, which provides for the high strength competent rock. Once drilled and blasted the solid rock is now fragmented into particle sizes of 500mm and smaller.
