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.

    Swiss civil engineering company Scrasa has made a successful investment in a Hitachi ZX470LCH-5 as the main production machine for its sand and gravel pit. The large Zaxis-5 excavator was delivered to Scrasa’s Satigny site on the outskirts of Geneva by the country’s Hitachi dealer, Probst Maveg. The ZX470LCH-5 is part of a fleet of machinery that includes two ZX225USLC-5s, a ZX135US-5 and a ZX85USBLC-5, but it is the only machine based at Satigny. Scrasa said the ZX470LCH-5 plays a key role in the excava

  • Cold recycling with foamed bitumen – an innovative technique
    November 7, 2017
    The pressure to conserve materials in road construction means that resource-saving technologies are more in demand than ever before. Wirtgen’s cold recycling process is already proven and has the potential to meet future demand. Roads subjected to continuous and heavy traffic often show signs of damage that extend down to the road base. To eliminate this damage, the entire road needs structural rehabilitation. Full reuse of the milled material as well as its cost-effective treatment make cold recycling with
