Dimension Stone
Quarry blocks are subdivided by breaking them into smaller blocks that can be removed from the quarry and sent to the mill. Typical mill blocks range in size from 12 to 30 t, but they can reach weights as large as 65 t. Quarry operations thus involve cutting the stone, breaking the stone, and removing the stone from the quarry.
