Gravel is a loose aggregation of small, water-worn or weathered rock fragments, usually with a particle size range of 2 to 60 mm. It is a common construction material, used for both functional and decorative purposes. Gravel is often used as a base layer in road construction, as a drainage material, and in landscaping and gardening projects. It can also be used as a decorative element in gardens, walkways, and outdoor living spaces. Gravel is available in a wide range of colors and sizes, including river rock, crushed stone, and pea gravel. The type of gravel used depends on the project’s specific needs and design requirements.
A sand washing machine, also known as a sand washer, is a machine used to wash and remove impurities from sand and other granular materials such as gravel. It is widely used in construction sites, sand and gravel plants, concrete dam sites of hydropower stations, and other industries.
The sand washing machine works by separating sand and gravel through the agitation of the impeller and then discharging the impurities from the overflow port. It can remove impurities covering the surface of the sand and destroy the water vapor layer covering the sand particles, which helps to facilitate dehydration and plays a role in efficient sand washing.
There are different types of sand washing machines available in the market, including spiral sand washing machines, wheel sand washing machines, and vibrating sand washing machines. The choice of machine depends on the specific needs and requirements of the user. Some sand washing machines are also equipped with recycling systems that allow the washed water and materials to be recycled and reused.
Sand washing machines are commonly used to clean and separate sand and gravel materials for construction purposes. These machines use water to wash and remove impurities from the sand and gravel, such as clay, silt, and other unwanted particles. By doing so, the sand becomes suitable for use in construction projects, such as making concrete or asphalt, as well as for other applications such as landscaping and sports surfaces.
