Background
River sand is a naturally occurring granular material composed of finely divided rock and mineral particles (primarily silica) ranging between 0.075mm to 5mm in size, formed through prolonged erosion and water transport that gives it characteristically rounded, smooth grains. Extracted from riverbeds and floodplains, this high-quality construction material exhibits excellent gradation with minimal clay/silt content, offering superior workability in concrete/mortar applications due to its optimal particle shape and distribution. Its natural washing process during fluvial transport results in cleaner particles compared to other sand types, requiring minimal processing for most construction uses, though industrial applications often employ mechanical washing (typically via bucket wheel systems) to achieve higher purity standards. Valued globally for its binding properties and permeability, river sand serves as fundamental aggregate in concrete production, masonry work, road construction, and landscaping, while also finding specialized uses in glass manufacturing, foundry casts, and water filtration systems.
Solutions
This 200-ton-per-hour river sand washing production line features a fully automated process where raw sand is first conveyed by belt conveyor to a high-efficiency bucket wheel washer that thoroughly cleanses the material through intense scrubbing and hydraulic classification, effectively removing clay, silt and organic impurities while preserving sand grain integrity, then the purified sand is discharged via another belt conveyor to storage or further processing, with the entire system designed for continuous operation, low water consumption and minimal maintenance, making it ideal for large-scale production of construction-grade sand that meets international quality standards for concrete work and other industrial applications.
