The powder not screened out in the screening disk 602 is activated by the controller 7 by the vacuum cleaner 607 and the electromagnetic control valve 608, so that the powder not screened out in the screening disk 602 is transported to the grinding barrel 408 for grinding again.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
