Liebherr says its LRT 622 provides efficient and cost-effective concrete recycling
718 Liebherr claims its three-size LRT 622 trough system recycling plants provide cost-effective and efficient separation and recycling of pre-hardened concrete components from batching plants and truck mixers.

Process water from each recycling plant, collected in a sump tank and suspended by an agitator, is returned to the production plant. Sand and gravel is then washed clean ready for re-use as production aggregates.

The trough pattern on the LRT 622 holds a high amount of wash water so that larger quantities of material for recycling can be added at shorter intervals.

A sizeable loading hopper can be filled from virtually any angle and can contain up to two truck mixers at any one time.

The LRT 622 Concrete Recycling Plant has a trough length of 6000mm; a trough diameter of 2200mm; a solids discharge height of 2000mm; a drive motor rating of 11kW; and a throughput capacity of up to 20m³ per hour.

    US and European asphalt paving needs are different, but some firms are bridging that gap, reports Mike Woof. With a clear differentiation between the US and European asphalt paving markets, manufacturers from the latter are now developing machines aimed at the former. The US and European markets for paving machines have developed along very different lines. North American pavers are designed for high throughputs and high paving rates, having been designed to meet a need to build roads over long distances wi

    A massive construction project has been underway deep in the heart of the Schnecktal valley area in Germany. From the surface, though, you would never be able to tell. The majority of the work is underground, as a joint-venture team led by German contractor Wayss and Freytag Ingenieurbau builds the nearly 7km long Finne Tunnel. After a few years of tunnel boring operations, the contractor is at work finishing the interior of the tunnel, slipforming first the tunnel’s floor and then a walkway with its GOMACO
