Ammonium nitrate crushing device

The utility model relates to a crushing device, in particular to an ammonium nitrate crushing device. The interior of the shell is divided into the coarse crushing working area and the fine crushing working area, the coarse crushing working area and the fine crushing working area can be used independently and do not influence each other, the coarse crushing area is located obliquely above the fine crushing area, and large-particle-size unqualified particles generated in the coarse crushing process roll downwards along the inclined face of the upper portion of the coarse particle inclined sieve plate. And the raw materials penetrate through the formed particle channel to a fine crushing working area and are directly used as fine crushing raw materials, so that manual collection, recovery and re-carrying are avoided, meanwhile, mechanical transportation is not used, and manpower and material resources are saved. A temporary material storage space is arranged, a turning plate is arranged below the temporary mate
