  • INTRODUCTION

    The use of manufactured sand as a replacement for river sand is increasing with the ban on sand mining 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.

  • URBAN GROWTH

    The phenomenal rise in the construction activity in the last decade has contributed to the wide gap between the supply and demand of river sand. A lot of damage has been caused to the eco-systems by carrying out dredging operations on the sand beds leading to the depletion of ground water levels in the country.

  • ROLE OF FINE AGGREGATES IN CONCRETE

    It is accepted fact that sand plays a very important role in the production of concrete. The features of workability, strength and durability are directly dependent on the properties of the sand used in the making of concrete.

  • CONCEPT OF MANUFACTURED SAND

    According to industry reports there is a major shift in the mindset of the Construction Industry towards exploring substitutes for river sand. Across the world, there is growing support for manufactured sand usage in the production of concrete. The properties of particle shape, consistent gradation and zero impurities are the reason for the preference by structural consultants and concrete technologists. The imperative need for clean sand, eliminating the constraints of river sand like availability, price fluctuation etc, have made manufactured sand the perfect substitute for river sand..

  • MANUFACTURING PROCESS AND ITS STANDARDS

    The sand is manufactured in a three stage crushing process. The raw material is either granite or basalt rock. The VSI which is also referred as sand making machine is in the Tertiary Stage. The process adopted is similar to the river sand generation by nature. The VSI applies the principle of rock on rock collision at a high velocity shaping the sand particles.

    The plant works on the principle of continuous feed in closed circuit and adopts the technique synonymous and comparable to nature's production of river sand. The complete manufacturing process takes minutes when compared to the nature which happens over millions of years.

Quality Tests Performed

  • Sieve Analysis
  • Silt Test
  • Imapct and Crushing Value Test
  • Mix Designs for optimum ratio

The Sieve Analysis tests are conducted on RoboSandTM RoboAggregates 20mm and 10mm everyday on samples collected from conveyor belts, stockpiles and loaded trucks.

The following equipment is required and is available at all our plants,

  • Sieves of different sizes
  • Sieve Shaker
  • Oven
  • Sampling Cones

All our sales officers are also trained to carry out these tests at customer locations.

The Vertical Shaft Impactor applies a similar principle of rock-on-rock collusion for crushing.

The sand is classified into four zones as per IS 383 norms.

Zone I is coarser and becomes finer towards Zone IV.

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.

The plant consists of three circuits, namely primary circuit, secondary circuit and territorial circuit where in a three stage crushing takes place. A 500mm down size granite rock that is brought from the quarry via operations which involves drilling, blasting, segragation, secondary breaking and transportation to the plant, is fed into the primary circuit consisting of one jaw crusher that sizes down the granite rock to produce 150mm down size aggregate. This 150mm downsize rock is fed into the secondary circuit consisting of one cone crusher to produce 40mm down size aggregate which in turn fed into the teritory circuit consisting one vertical shaft impactor that produces sand and aggregate of the required gradation and shape.The installed capacity of the plant is 200 TPH.
