This automatic iron removal device has a large number of magnet bars arranged so as to cross the rectangular iron removal chamber, and from the raw material flowing through the iron removal chamber, magnetic materials such as fine iron powder and iron fragments mixed in are removed. Foreign matter is removed by adsorbing with a magnetic bar.

ところで、このような自動脱鉄装置では、原材料として粉体を脱鉄処理することが多いが、粉体の種類によってはブリッジしやすいものも多い。
特に、従来の自動脱鉄装置では、多数のマグネットバーを原材料の流れ方向に直交するように配設することから、マグネットバーの上流側に粉体のブリッジによる粉溜まりが発生しやすく、これを防止するためにバイブレータが別途必要になるなどの問題があった。
特開平６−２６９６９５号公報 By the way, in such an automatic iron-removing apparatus, a powder is often de-ironed as a raw material, but depending on the type of the powder, there are many that are easily bridged.
In particular, in a conventional automatic iron removal device, a large number of magnet bars are arranged so as to be orthogonal to the flow direction of the raw material, so that powder accumulation due to a powder bridge tends to occur on the upstream side of the magnet bar. In order to prevent this, there was a problem that a vibrator was required separately.
JP-A-6-269695
