A bucket crusher or crusher bucket is a type of jaw crusher. It's an attached tool for excavators for built-in crushing construction waste and demolition materials. It has the design of a shovel, which is open at the rear for releasing the shredded material. Compared to normal jaw crushers, the jaw crusher bucket has a lower production, but can be transported more easily and only needs an excavator to operate.
Bucket crushers are primarily employed in mining and demolition for the breaking-down of crude minerals, concrete and masonry.
