The occurrence of river sand is based on the river bed. The surface layer is inclined from the river bank to the river bed, and the slope is inclined from the upstream to the downstream. The apparent density of the river sand is 2580kg/m3, the bulk density is 1569kg/m3, and the fineness modulus is 2.89. The mud content is 1.34%. River sand has the characteristics of hard texture and clear color and is a good building material.
Sand washing machines generally include impeller sand washing machines, spiral sand washing machines, drum sand washer etc. The sand washer has features like low water consumption, low volume, and low investment. Impellers use wear-resisting plate or polyurethane material so as to reduce the running cost. Simple structure, rarely requiring maintenance, thus greatly reducing costs.
