Description : Crusher Bucket, FB Series, is an excavator-mounted bucket attachment that allows for portable and affordable crushing operations on site. It processes material to produce sub base on site, using available materials at a fraction of the price of purchasing or renting a traditional portable jaw crusher. A quick and easy adjustment of the thickness of incoming material allows one to adjust output material size from 15 mm (0.6-inches.) down to 130 mm (5.0-inch.).
