This video presents a live operation demonstration of two of the most widely used sand washing machines in aggregate processing and construction material production: the wheel sand washer and the spiral sand washer. Both machines are manufactured by Xingaonai Group and are shown running under real operating conditions, allowing engineers, plant operators, and procurement professionals to observe and compare the working characteristics, output quality, and operational behavior of each machine type in a single viewing session.
Sand washing is an essential stage in the production of clean, specification-compliant aggregate for concrete, mortar, road base, and asphalt applications. Raw sand and manufactured sand produced by crushing operations invariably contain surface dust, clay particles, silt fines, and other contaminants that reduce the quality and commercial value of the sand product. Washing removes these contaminants, improves the cleanliness and gradation of the sand, and produces a product that meets the quality standards required by concrete producers, construction contractors, and aggregate specifications in most markets worldwide.
The choice between a wheel sand washer and a spiral sand washer depends on the specific requirements of the application — feed material characteristics, required output cleanliness, acceptable fines loss, available footprint, and capital budget all play a role in the selection decision. This video provides the most direct possible basis for that comparison by showing both machine types working simultaneously.
