Manufacturing Sand-A Perspective

Evolution of Fine Aggregate Industry in India

The attempts to produce crushed or manufactured sand in India could be traced to early 50's primarily in major dam works. The focus was on using different size reduction technques with available resources like rod mills, roller crushers, and cone crushers.

Technical Perspective

The use of manufactured sand as a replacement for the river sand is increasing with the ban of sand minining implemented by different states. The other factors are the general decline in the availability of river sand and pressure from active environmental groups to protect the nature.


Our Quarrying process typically begins with drilling and blasting the rock into smaller pieces.Bore holes are drilled in the blast site and filled with explosives. The blast breaks up into smaller pieces that are loaded and hauled to the plant.

Quality Testing

The seieve analysis tests are conducted on RoboSandTM 20mm and 10mm everyday on samples collected from conveyor belts, stock piles and loaded trucks.
