Sand Making and Sand Washer in Construction

August 21 [Tue], 2012, 15:58
As we all know, sand is the essential material for construction industry, its quality has an important influence on the quality of construction works. Now, the quality of nature sand is declining due to the disorderly exploitation and the depletion of resources. Instead, the project construction is more and stricter in the sand quality. Sand washer is a kind of sand washing equipment, in the washing process, the stones, mud and other impurities will be greatly reduced, the quality of sand will be significantly improved.
Sand washing machine drives the impeller in the water groove to move like a circle transmitted by motor and decelerator, and then mixes, overturns, cleans and discharges the sand or slag pellets in the water groove. Sand washing machine is widely applied in the following industries: quarry, minerals, building, transportation, chemical industry, water conservation and hydropower, cement mixture station and so on. The sand is washed to remove fine particles(silica sand washing machine for sale)Silica sand washing machine for sale . Washing is done by spraying the sand with water as it is carried over a vibrating screen (mobile vibrating screen). The fine particles are washed off the sand and the coarse particles are carried along the screen by the vibration. Some processing operations also use what is called an upflow clarifier to wash the sand. An upflow clarifier is essentially a tank where water and sand are continuously directed into the tank. The water washes the sand and the overflow water along with the fines overflow the tank while the washed sand falls by gravity to the bottom of the tank and is sent for further processing.
After washing the sand is then sent to a surge pile where much of the water adhering to the sand particles infiltrates back into the ground. For example, in Wisconsin the wet portion of the processing facilities typically runs from April to mid November. The drying portion of the process can operate year round thus necessitating stockpiling of washed sand adequate to last through the winter processing months. As the professional manufacture of sand washer, Henan Hongxing Mining Machinery will work hard to promote and guarantee the quality of sand washer based on our years of experience.
