Molding Sand: Types and Properties [PDF]
Dry Sand: Dry sand is the type of green sand, from which moisture is being removed. Dry sand is made by baking or drying the mold made from the green sand in a decent oven. The dry sand contains a mixture of 15% to 20% of clay and silica. This sand has more rigidity, thermal stability, and strength.
sand silica drying
Silica sand is a more commonly heard description of sand than is washed sand. That's because silica sand is one of the most abundant sands in the world, whereas sand that is washed, or washed sand, refers to a level to which sand is processed.

What is Industrial Sand?
Silica sand deposits are most commonly surfacemined in open pit operations, but dredging and underground mining are also employed. Extracted ore undergoes considerable processing to increase the silica content by reducing impurities. It is then dried and sized to produce the optimum particle size distribution for the intended appliion.
