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 ? Further, the fines will stick onto the interior of pug mill and its content will be low. The mixed material is stockpiled for weeks / months before use. 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.
