SIEVING DEVICE, SIEVING SYSTEM, AND SIEVING METHOD

摘要

PROBLEM TO BE SOLVED: To solve the following problem: because a sieving device having a cylindrical sieve has a mechanism sending powder out from an inside region of the cylindrical sieve to an outside region, a large space is needed so as to collect the powder having passed thorough the sieve, and the size of the sieving device is increased by using the cylindrical sieve.

SOLUTION: This sieving device 100 includes a blade 131 rotatably disposed close to a filter 122 with a rotational axis Z crossing the filter 122 as the center. A moving direction of the powder passing through the filter 122 is narrowed down to a direction of the rotational axis of the blade 131, so that it is not necessary to secure the large space so as to collect the powder having passed through the filter 122. The sieving device 100 can avoid the increase of the size of the device by using the blade 131.
