Bottom roller guide for a sliding shutter in spiral chutes in underground mining |
| 摘要 |
The invention relates to a bottom roller guide for a sliding shutter (5). The top edge (13) of the bottom guide rail (8) is arranged a considerable distance (T) below the bottom edge of the opening (4) to be closed by the sliding shutter (5). A high self-cleaning effect of the guide for the rollers (17, 18) is thereby achieved. <IMAGE>
