PROBLEM TO BE SOLVED: To provide a crusher which can prevents not only coarse particles generated in the crusher itself but also fine particles from scattering outside.SOLUTION: In the crusher 1 for crushing an object to be crushed thrown through a throwing part 3 in a crushing part 4, a shutting part 6 so composed as to receive the object to be crushed from the throwing part 3 in a state that the crushing part 4 is closed and transfer the object to be crushed to the crushing part 4 in a state that the throwing part 3 is closed is formed between the throwing part 3 and the crushing part 4. Particularly, the shutting part 6 is configured by tightly setting a transversely long column-like drum 18, in which a storage space 19 for storing the object to be crushed is formed in a groove-like form by digging, in the shutting part body 16 in a freely rotating manner so that the object to be crushed can be received and transferred by rotating the drum 18. |
