the materials which are crushed and qualified on the uppermost screen plate 7 fall into the next screen plate 7 from the screen holes 23 on the screen plate 7, and are continuously crushed by the crushing roller 8; part of the materials fall onto the blades of the auger in the rotary drum 14 along with the notch 15 on the rotary drum 14 when the screen plate 7 shakes in the crushing process, if the crushing degree of the materials is qualified, the materials fall from the sieve holes 23 on the auger blades and fall onto the centrifugal plate 22 to be thrown out into the storage bin 9, if the crushing degree of the materials is unqualified, the materials are conveyed upwards by the auger blades and then are sent out from the top end of the rotary drum 14, and return to the uppermost screen plate 7 again for crushing;
when the uppermost screen plate 7 is crushed, a small amount of materials are thrown out from the screen plate 7 or separated from the screen plate 7 along with the shaking of the screen plate 7, at the moment, the materials fall onto the guide ring 5, fall onto the next screen plate 7 along the flexible ring 25 on the guide ring 5, and the crushing flexible ring 25 is continuously carried out, so that interference between the screen plate 7 and the guide ring 5 can be avoided;
the motor 11 is arranged in the storage bin 9 relatively in a sealing way, so that crushed materials are prevented from entering the motor 11 to influence the operation of the motor 11; the bottom slope of storage silo 9 sets up, and the material that is convenient for smash the completion flows out.
