Claims

[Scope of utility model registration request]

A hot air supply pipe that communicates with one end of the tube mill and rotates about its axis; a transport tube that surrounds the hot air supply pipe and is coaxially arranged and communicates with one end of the tube mill; and a transport tube that is attached to the outer peripheral surface of the hot air supply pipe. a conveyor blade that supplies the material to be crushed between the hot air supply pipe and the transport tube to the tube mill; a conveyor tube that surrounds the transport tube and is coaxially arranged and communicates with one end of the tube mill; a cyclone-type classification device that has a heavy structure and has an inner cylinder communicating with the transport cylinder and an outer cylinder communicating with the conveyor cylinder;
1. A crushing device comprising a raw material supply tube inserted into an inner tube of the classification device to supply raw materials to be crushed.
