The spiral sand washer (SL series) is able to wash and separate the soil and other impurities in sand and gravel aggregate. The enclosed structure, adjustable overflow weir plate, and reliable transmission parts increase the cleaning and dehydration effect, which can be applied to road, hydraulic, and construction industries. The main features are listed below. 1.The structure is simple. The bearing device of impeller driving is isolated from the washing water and sand thus largely decreasing the failure rate. The loss of fine sand and stone powder in sand washing plant is small. The washed sand is of good gradation; the fineness modulus can easily meet the requirements of relevant standards. Almost no components of the machine are vulnerable to wearing and breaking down except the screen.
