Dust retention device |
摘要 |
The device is for retaining dust when particulate material is dumped through the device into a container. The device has a plurality of adjacent inverted-V shaped restrictors which swing about an axis along the point where the two leaves of the V meet. There are material deflectors which unevenly load some of the restrictors.
