Artificial Sand Production Line

The material will primarily go through crushing and screening process, and then industrial sand and gravel are washed to remove impurity materials and debris and are then screened and classified again.

The sand (now containing 25 to 30 percent moisture) or gravel then goes to the sand washing machine attrition scrubbing system that removes surface stains from the material by rubbing in an agitated, high-density pulp.

The scrubbed sand or gravel is diluted with water to 25 to 30 percent solids and is pumped to a set of cyclones for further desliming.

If the deslimed sand or gravel contains mica, feldspar, and iron bearing minerals, it enters a froth flotation process to which sodium silicate and sulfuric acid are added.

The mixture then enters a series of spiral classifiers where the impurities are floated in froth and diverted to waste. The purified sand will be dried for final applications.
