Impact assessment of river sand resource shortage under
More than half of the annual global concrete materials were produced in China due to the rapid developing construction industry, which partly led to the shortage of river sand. However, mining rate exceeds the natural replenishment rate of river sand recently, resulting in depletion of natural river sand accumulation. The increasing most widely distributed sand washing machines in the World to the sector defining AggreSand the World’s first chassis mounted integrated system offering 5 washed products TWS is always innovating, always one step ahead.

Exploring the characteristics, performance, and mechanisms
Hence, a rapid low-cost environmentally safe countermeasure is needed. This study proposed a novel treatment of oiled beach sand using a magnetic-mediated washing fluid. The comprehensive performance evaluation, mechanism analysis, and thermodynamic modeling were conducted to explore the washing process.In a waste water treatment process and assembly, incoming sand is separated from other substances and is washed in a combined process. Having been freed of coarse particles or solid objects, the water is agitated for a given time within a vessel which has number of fixed inner projections, and in which particles are separated by density.DE19844034A1 Process to remove and clean sand particles

Análisis técnico-económico de alternativas para la SciELO
The use of centrifugal classification in the sand washing process is economically attractive. For its execution an initial capital investment of $ 335 114 is required, being recovered in less than 3 years. With this technology 1.56763 t of water/t of sandstone processed and 0.32405 kWh/ t of sandstone processed are saved in the analyzed plant.A flow diagram of a washing process is shown in Fig. 6. This process for a sandy soil with low organic content that disperses easily in water consists of (1) spray washing sand through a 3–6 mm screen large enough to pass 30 tph of solids, (2) washing, hydrosizing and drying sand in a sandscrew, then (3) dewatering the finer soil.Simplified soil washing processes for a variety of soils
