図1に示す原料供給装置4は、図2に示すように、コンベアなどからなる第1の搬送手段2の搬送面2aから、第1の搬送手段2の下方にある第2の搬送手段1の搬送面1aへと原料を供給するような種々の処理装置に対して好適に用いることができる。図2の例では、形状及び比重の異なる種々の物質を含む電子・電気機器部品屑の処理装置に適用した例を示している。
図1~図4に示す原料供給装置4及び電子・電気機器部品屑の処理装置は、風力選別機、メタルソータ、カラーソータ、篩別機などの種々の選別機を用いた電子・電気機器部品屑を選別するための選別処理工程への適用に特に好適である。
原料を垂直方向の特定範囲に集約して落下させるために、図1に示す原料供給装置4を作製した。原料供給装置4の上方にあるコンベアの搬送面の有効幅を600mm、原料の最大直径を50~70mm、原料の搬送速度を36m/minと想定した。原料としては、基板、ICやコネクタ等のパーツ、筐体などに使われる合成樹脂類(プラスチック)、線屑、メタル、フィルム状部品屑、破砕や粉砕によって生じる粉状物、その他、からなる電子・電気機器部品屑と、アルミ板(20mm×50mm×0.5mm)を使用した。受入口43が備える第1の開口433の寸法を600mm×320mmと設計した。排出口42が備える第2の開口422の第1の寸法S1を600mm、第2の寸法を50mmと設計した。第2の案内面411の傾斜方向に沿って延長した延長線と第1の案内面412との交点Pから第1の案内面412の最下端部までの長さL1を50mmとし、第1の案内面412の最下端部から分散器3までの長さL2を70mmとし、排出口42が備える第2の開口422の直下に分散器3の原料落下領域31がくるように位置を調節した。なお、第2の案内面411の傾斜面411aの傾斜角度θ2は、70°とした。
分散面の数が異なる分散器を作製し、処理原料の分散挙動を評価した。分散器はプラスチック段ボール製で、分散面が2~5面のものを作製した。各分散面は二等辺三角形とし、各三角形の底辺をそれぞれ等しくした。分散器の底面に対する各分散面の傾斜角度を45°で設計した。処理原料としては、評価を容易にするために、アルミ板(20×50×0.5mm)を使用した。結果を図5に示す。
図1に示す処理装置において、搬送速度36m/minの第1の搬送手段から、原料として、電子・電気機器部品屑とアルミ片とを原料供給装置4へ向けて落下させて、分散器3から第2の搬送手段1上の搬送面1a上に原料を分散させた。分散器3が備える各分散面3a~3e(図4のA~E)を沿って搬送面1a上へ落下した原料の重量をそれぞれ求めた。結果を表2に示す。
