Telebelt Delivers Materials

With a large part of the concrete placement now done, a TB 130 mobile conveyor belt system is being used. This conveys unpumpable, pourable bulk materials into the site of concrete placement via a telescoping conveyor belt.

Typical materials include excavated material, hardcore, sand, humus, bark mulch and granulated or extremely stiff, earth-moist concretes.

The Telebelt - before installation of the final layer and the construction concrete – had conveyed dry filling and tamped concrete (consistence class F1) as well as sand and hardcore into the various pits.

The building materials were initially passed onto the Telebelt feed conveyor either by truck mixers, truck tippers, mobile excavators or wheel loaders.

The material was then transported up to 39 m along the main telescoping conveyor belt and distributed with the required precision.

The belt movements and the delivery rate are controlled by radio remote control, similar to the control of the PM truck-mounted concrete pumps. Even an inclined raising or lowering of the delivery belt is possible. The actual installation performance of the TB 130 depends on the type of bulk material, the construction site logistics, the waiting times between the batches, etc. The Telebelt is designed for an output of up to 270 m³/h (max./theor.).

New High efficiency Coal Power Plant

The two new power plant blocks of RWE Power AG will be fired with coal and petrol coke. With an efficiency of approximately. 46%, the new two-block plant will be one of the most modern and efficient coal power plants in the world. Blocks “D” and “E” should be connected to the grid by the start of 2012, and blocks “A” and “B” which have been in service since 1962/63 (output per 160 Megawatt) will be shut down.
