  • Washing of Aggregates Influence on Aggregate Properties

    reference aggregate in the washing experiments in this work 22 Methods Washing procedure The aggregates were washed in the laboratory by using a bucket and stirring machine The washing procedure was as the following (Figure 1); the aggregate was suspended in water and agitated vigorously Thereafter, coarse particles were allowed to sediment· Aggregate producers need to wash concrete and asphalt sands for several reasons They need to remove lightweight particles such as lignite, mica and shale They need to remove other undesirable particles such as sand in a gravel pile Producers often have to alter feed gradation to meet a design spec And many times, producers need to blend multiple feeds when material is being suppliedSelecting the Right Aggregate Washing & ClassifyingThe washing of aggregates is required for many markets and applications Nowadays the finished product needs to meet specifications outlined by the ever stringent and demanding world markets Where dry screening was accepted in the past, washing and scrubbing are now required to produce a silt free product Industry leading washing equipment A typical rinsing setup would be used when theAggregate Washing | PowerX Equipment
