Robo sand is a artificial sand, that is now increasingly
bein referred b leadin builders, develo ers across the
country, having proved its mettle and superiority over
river sand.

Vital to construction, both for concrete and masonry
work, and needed in large quantities, sand has been
traditionally lifted from dredging of creeks and
riverbeds which in recent times has been causing
environmental worries over possible groundwater
depletion.

To reduce dependence on river sand for construction
purposes, the new mechanised sand made from
granitegranitegranitegranitehas been positioned as an ideal substitute in
all aspects. Those promoting the Robo Sand describe
it as a quality material offering same strength forstructures and better than the conventional sand in
some features.

Robo Sand protects environments, promotes ethical
and legal construction and also eliminates all the
disadvantages of river sand. Apart from this, using
results in substantial saving of cement and thus
slashing the construction costs.

PROCESS
The plant consists of three circuits namely
Primary circuit, Secondary circuit and Tertiary
circuit wherein a three-stage crushing takes place.

A 500 mm down size granite rock that is brought
from the quarry via operations which involve drilling,blasting, segregation, secondary breaking and
,
Circuit consisting of one Jaw Crusher that sizes down
this granite rock to produce 150mm down size
aggregate.

This 150 mm down size rock is fed into the
Secondary Circuit consisting of one Cone Crusher to
produce a 40 mm down size aggregate which in turn
is fed into the Tertiary Circuit consisting one Vertical
Shaft Impactor that produces Sand and Aggregate of
the required Gradation & Shape.

Thus the process is quite similar to Mother
Natures long drawn out process of creating sand,but here characterised by acceleration that
telescopes formation time into minutes.

RoboSand is in fact GREEN SAND it is an eco-
friendly product, in the sense, it shows an alternative
to the ill- effects (gground water depletion, water
scarcity, fall in farm production,Threatening the very
safety of the Bridges, Dams etc.)of dredging,mining
and indiscriminate quarrying of river beds which isposing a great threat to the environment.

Defects RoboSand has optimum initial and final
setting time as well as excellent fineness which will
help to overcome the deficiencies of concrete such as
segregation, bleeding, honeycombing, voids and
capillary.
Unmatched Economy RoboSand offers great savings
and helps in slashing overall project cost.
