ABSTRACT:
A crusher which is simple in structure and capable of dismantling a building structure and recovering iron material from among dismantled remains of a building. A movable jaw is provided so as to be opened and closed relative to a fixed jaw fixed to the crusher main frame. A magnetic case made of a nonmagnetizable material is provided on the bottom of the main frame. A permanent magnet assembly is slidably mounted in the case. The permanent magnet assembly is connected to a hydraulic cylinder for sliding the permanent magnet. By actuating the hydraulic cylinder, the permanent magnet will move down so that iron material is attracted through a bottom plate of the magnet case. By raising the permanent magnet assembly, the magnet weakens, so that the attracted iron material drops by gravity.
