Compared with the prior art, the utility model has the following beneficial effects:

[0015] The optical disc falls into the knife box through the feeding chamber, and is crushed and destroyed by the crushing tool. Due to the low melting point of the optical disc material, the heat generated during the crushing process will cause the optical disc fragments to stick to the crushing tool. At this time, the sticky fragments can be scraped off by the knife comb, and fall into the discharge chamber with the crushed optical disc fragments. The fragments that do not meet the safety requirements will be retained on the filter screen at the top of the discharge chamber, waiting to be scraped back to the crushing device by the brush for re-crushing until the particle size of the optical disc fragments reaches the safety level. The utility model has a simple structure, does not require heat treatment during the working process, saves energy, can realize the function of returning and destroying unprocessed materials, and meets the safety level.
