Excavator Rock Crushing Bucket

CTHB crusher buckets are used for crushing recycling materials: concrete, rock, asphalt, building or construction waste, foundry waste, and glass waste. Crushing buckets break these materials into small-diameter pieces. Then, small-diameter rocks could be sold as construction material, and those small-diameter waste pieces could be recycled and reused.

Rock crusher buckets are also known as jaw buckets because they have two crushing jaws, one fixed and the other moved by a motor. First, the operator digs the rock; the excavator offers hydraulic power to drive the motor, then buckets start to crush the rocks. The operator can adjust the plate inside of the buckets to control the diameter of the rock that comes out of the bucket’s bottom side…..
