Description

Crusher Technical field: The utility model belongs to the technical field of crushers, and particularly relates to a crusher. The background technology is as follows: In daily life, scrap metal such as scrapped household appliances, motors, bathroom parts, new energy batteries and the like mainly comprises copper, aluminum, iron, plastics and the like, and crushing recovery treatment is needed. Among them, as a device capable of breaking large-sized materials into small-sized materials, a rotary breaking hammer is generally used to hammer waste metals to form small-sized materials. However, the conventional hammer crusher relies on impact force, but the metal has strong ductility, the hammering easily causes deformation rather than fragmentation of materials, repeated crushing is needed, the efficiency is low, and the energy consumption is high. Meanwhile, the scrap metal is hammered to easily cause unordered rebound of metal fragments, and part of fragments fly out of the feed inlet during rebound, so that serious safety exists.
