The solution used to manufacture NEOSAND has been provided by METSO – Finland, who are world leaders in providing crushing & screening solutions.
The solution involves a 250 Metric Tons Per Hour 4-stage crushing & screening process, using imported machinery in the order of: 
Jaw Crusher -> Cone Crusher -> Vertical Shaft Impact (VSI) Crusher -> Dry Air Classifier
The raw material, granite grade boulders of high quality are sourced from our quarries and fed to the primary Jaw Crusher. 
The material is down sized and shaped as it progresses through the first three stages. 
The VSI with its rock-on-rock crushing action improves the soundness and shape of products. Aggregate particles that are cubicle in shape are ideal for maximizing the strength of mortar and concrete.
NEOSAND is further passed through a fourth stage consisting of Dry Air Classifier to remove excess ultra-fines (150 micron) to keep its percentage within grading envelopes defined by IS:383. Contrary to the previously used washing technique which uses lots of water, our new imported technology does not require water and uses air flow, gravity and directional changes to produce NEOSAND of superior quality
