Draglines are used to dispose the overburden for exposing minerals in a surface mine. Draglines may be greater than 4000 t in overall weight, with bucket capacity ranging from 24 to 120 m3. The buckets are dragged against the blasted muck to fill the blasted overburden materials1. Bucket teeth fail easily while the excavator is being operated due to the fact that they are in direct touch with the rocks. The bucket teeth have an appropriate geometrical design for longer life and cost reduction2.

Abstract


Draglines are used to dispose the overburden for exposing minerals in a surface mine. Draglines may be greater than 4000 t in overall weight, with bucket capacity ranging from 24 to 120 m3. The buckets are dragged against the blasted muck to fill the blasted overburden materials1. Bucket teeth fail easily while the excavator is being operated due to the fact that they are in direct touch with the rocks. The bucket teeth have an appropriate geometrical design for longer life and cost reduction2.
