<p>PROBLEM TO BE SOLVED: To provide a shot treatment apparatus that is capable of accurately separating foreign matters from a projection material.SOLUTION: A mixture containing a projection material and granular foreign matters is flowed into an internal part of a sieve body 42A of a rotary screen 42. When the sieve body 42A rotates about a shaft, the mixture is brought in rolling motion by which foreign matters having a diameter larger than that of holes 42B are removed. Further, a part of the mixture passing through the holes 42B of the rotary screen 42 is attracted by a first magnetic separator 66 using magnetic force of a first magnet, in order to be separated and discharged. Moreover, a part of the mixture that is not attracted by the first magnetic separator 66 using the magnetic force of the first magnet is attracted by a magnetic separator 82 using magnetic force of a second magnet, in order to be separated and discharged.</p> |
