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.

    Asphalt plant producer Ciber discusses asphalt mix properties The basic quality criterion of an asphalt mix is its adhesiveness; the adhesion capacity among materials. This adhesive capacity of the asphalt mix can be measured in the laboratory through qualitative or quantitative tests. The result of this analysis should be used as a reference for the improvement of the mix. In the laboratory this can be achieved using additives while at the plant it can be achieved using differing mixer technology an
