[0024] In order to make the putty powder drying and in the collection hopper 18 heat preservation for a period of time, the discharge pipe 6 on the installation of unloading valve.
[0025] The working process of the embodiment is as follows:
[0026] In use, the putty powder is fed into the housing 1 by the screw conveyor 3, and is first broken up as it passes through the feed plate 21. The putty powder passes through the holes in the feed plate 21 into the housing 1, and the rotating shaft 8 is rotated by the motor 7, which in turn rotates the cutter head 9 and the scraper 10. The falling putty powder is secondly broken up by the cutter head 9 and falls onto the coarse sieve plate 11. The impurities are then left on the coarse sieve plate 11 by the action of the scraper 10, and the putty powder falls onto the fine sieve plate 12. The fine putty powder is sieved out by the vibration of the fine sieve plate 12 by the vibration motor 14, and is collected in the collection hopper 18 and finally sent out through the discharge pipe 16. During the breaking up of the putty powder, the heat medium enters the heat preservation shell 2 through the heat medium inlet pipe 4 and exits through the heat medium outlet pipe 5, so as to provide sufficient heat for the inside of the housing 1.

After the device is used for a period of time, the sealing door 19 is opened, the impurities on the coarse sieve plate 11 are cleaned, and the putty powder that fails to fall on the fine sieve plate 12 is removed and fed into the device for breaking up again. There is part of the putty powder with a particle size smaller than the aperture of the fine sieve plate 12, which is temporarily accumulated in the collection hopper 18 if it is directly dropped. After the drying is completed, the discharge valve on the discharge pipe 6 is opened, and the material is sent out.
