THE STRONGEST UNDERGROUND CONVEYOR BELT |
| |
 |
The strongest underground conveyor belt is operating in a very interesting installation.
It is not only r.o.m. coal that is conveyed from 800 m underground to the surface but also, simultaneously, scalpings from the washing plant back underground.
The belt is 1400 mm wide, type St 7500, with 10 plus 12 mm covers including protecting reinforcements in both sides. |

It was commissioned in 1986 at the Prosper Haniel hard coal mine in Germany.
The capacity is 2000 t/h on the top run (uphill) and 1000 t/h on the bottom run (downhill). |
| The centre distance is 3745 m, the gradient is 12,3°. The belt runs at a speed of 5,5 m/s. There are two 3-phase current motors. |
