A simple separator – a hydrocyclone with overflow vacuum control – can be used to dewater the frac sand when there is a great deal of room available at the processing facility and the stockpile can sit for a longer length of time before being fed to the dryer.
Washed sand can begin as silica sand or any other type of sand and undergoes a washing and rinsing process after mining. Salt, clay, silt, and other powders and dust are washed out of the overall mixture. Washed sand often undergoes additional separating and classification into grain sizes or grit sizing.
