In an aggregate blending plant, water is sprayed before blending is performed. If the fine content in aggregate is as high as 25 %, will not the fines form into lumps / balls and distribution will not be uniform ?

Will it not be better that blending is done in dry condition, and water will be added only during compaction at site. Please forward your comments and suggestions.
