In order to allow a faster discharge into the Reclaimer and get concrete trucks back on the road, McLanahan Reclaimers can be supplied with large, infeed hoppers with augers that can meter the washout material into the Reclaimer. Once the washout material is introduced into the Reclaimer, sand is separated from the rock through the use of a low horsepower Rotary Trommel, which uses spiral flights that keep the material in contact with the screen as it is conveyed and washed. Aggregate material (+3/16″) is then washed and discharged into stockpiles directly from the Trommel. Trommels can be designed to make one, two or three size separations depending on the required specifications.
The remaining sand and cement fractions (-3/16″) go into a pump that pumps the material into a high-efficiency Separator™. This step separates the sand from the cement fraction. Sand is then discharged onto the ground or onto a high-frequency Dewatering Screen where it can be rinsed and dewatered further. Cement slurry can then be fed into a McLanahan Concrete Washout Water System that dewaters cement fines into dry, stackable cakes and recovers water for reuse in the plant. Alternatively, cement fines can be allowed to settle in conventional settling pits.
