The foreign matter having large fibers or other particles is configured to be caught by the strainer 7 and stored in the primary storage tank 10 formed at the lower portion through the granules having a predetermined size.

The primary storage tank 10 is in communication with the conveying screw 11 for conveying the granular material to the cyclone classifier 13, and the inclined plate 12 is formed on the bottom surface so that the foreign matter having large particles from the strainer 6 is formed. And the granular material filtered by the reinforcing fibers are slid down by the inclined plate 12 to be naturally collected by the conveying screw 11 to be conveyed to the cyclone classifier 13.

The cyclone classifier 13 is conical, and the blower 15 is staked on the side of the upper inlet 14 through which the powder is introduced into the cyclone classifier 13 through the transfer screw 11. Rotational flow is generated along the inner wall of the cyclone classifier 13 due to the strong blowing force of the The large powder is dropped into the secondary storage tank 17 through the lower outlet port 16 formed under the cyclone classifier 13, and the small particle size and light weight of the powder are separated from the cyclone classifier 13. Rising along the swirling air flow formed in the center is discharged to the upper discharge port 18 formed in the upper center is provided to be transferred to the foreign matter separation tank 20 along the transport pipe (19).

The granules having a large size and a large mass of particles dropped into the secondary storage tank 17 are again crushed by the transfer screw 11 ′ spread between the secondary storage tank 17 and the grinding unit 3. It is conveyed to and crushed while passing through the first grinding roller (4) (4 ') and the second grinding roller (5) (5') is configured to repeat the above process.

The foreign matter separation tank 20 is a long water tank and is used to remove residual foreign matters such as fine stone powder or metal powder mixed in the small and light granular particles classified from the cyclone classifier 13, and the water supply pipe 21 ) And a drain pipe 22 are provided.
