Bucket

Bucket-wheel excavators have been used in mining for the past century, with some of the first being manufactured in the s. They are used in conjunction with many other pieces of mining machinery (conveyor belts, spreaders, crushing stations, heap-leach systems, etc.) to move and mine massive amounts of overburden (waste).). While the overall concepts that go into a BWE have not changed.
