Pavement milling Wikipedia

Milling is performed by construction equipment called milling machines or cold planers. These machines use a large rotating drum to remove and grind the road surface. The drum consists of scrolls of tool holders. The scrolls are positioned around the drum such that the ground pavement is moved toward the center and can be loaded onto the machine's conveyor belt.

Radioactive Waste From Uranium Mining and Milling

Mar 02, 2020 Milling: This process takes place at a mill after the ore containing uranium is removed from the Earth through open pit or underground mining.The ore is brought to a mill, crushed, and ground up before chemicals are added to dissolve the uranium.
