After a ban on river sand mining in India Paobs invested in a CDE washing plant to produce manufactured sands from waste from their crushing operations.

Much of the sand supplied to the market in the Kaliyal region of India has traditionally been dredged from rivers. With growing pressure to reduce the environmental impact of such activities and ever increasing legislation operators are now looking at alternative methods of production for the sand products required to meet the requirements of the planned infrastructure developments in the region.

One such company is Poabs Granite Products who have been operating in the quarrying sector since 1986. The company has recently installed a 100tph sand washing plant from CDE’s Asian office with its headquarters in Kolkata. The plant was required by Poabs Granite in order to allow them to meet the growing demand for a manufactured sand product for use in concrete manufacture.

 

Manufactured sands washing plant for Poabs Granite

Poabs previously operated an extensive crushing operation in Kaliyal and while this brought the stone size down to a manufactured sand specification the problem lay in the high percentage of material passing 150 micron.

Using their previous system, the excessive fines content in the manufactured sand product meant that a large volume of water was required if the product was to be used to manufacture concrete. This essentially ensured that Poabs were not able to manufacture this product as it was not commercially viable.

The costs of production were so high that the concrete sand product was not able to be sold to the local market. The introduction of an Evowash sand washing plant from CDE has eliminated this barrier to market and allows Poabs to produce in-spec concrete sand at a price which has resulted in the company enjoying significant demand for the product.

The Evowash system is built around the philosophy that through proper testing of the feed material in the first instance accompanied by details of the final product specification required by the customer it is possible to ensure the production of high quality sand products which meet the target specification.

“CDE has become a name synonymous with world class sand washing systems across the world. The Evowash system is an industry leader in terms of both fines recovery and the production of high quality, high value material” explains Manish Bhartia, Managing Director of CDE Asia.

“As a company we pride ourselves on the design of an individually tailored solution for every customer. The installation with Poabs is proof that the system delivers the results required and we are looking forward to further introduction of the system throughout the Indian construction industry in the months and years to come.”
