Ramco Cements has commissioned Line-3 at its Ramamasamy Raja Nagar (R R Nagar) plant in Tamil Nadu which boasts of 3,000 tpd capacity of clinkerisation. This is the first integrated cement line commissioned in the last 15 years in the region. The electrical energy requirement for this new line is met through the company's own wind mills. The electrical energy requirement for this new line is met by its own wind mills.
With the commissioning, the requirement of limestone has shot up and subsequently, the company plans to install a wet beneficiation system at its mines, through which it can beneficiate marginal grade limestone/lime Kankar and the proper mix of various grades for the manufacture of cement clinker. The technology uses water as a basic beneficiating agent. Of the total water used in the process, around 90 percent of the water is being recycled back into the system. The remaining 10 percent of the water is also allowed to be absorbed into the ground through soak pits to rejuvenate the ground water level.
The company had engaged one of the premier material science research institutes, to develop a proper process design and system design for this application and procured equipment from a leading European machinery supplier. Moreover, the project got commissioned one month ahead in June 2023.
For sustainable business operations, the rejected/low grade ore can also be used for cement manufacturing, which helps to extend the mines' life.
The company manufactures a new plastering compound 'Ramco Eco Plast' (self-curing plaster) at this plant, as well as a special cement 'Ramco 53 Infra Super', especially for high-tech concrete structures, which reduces the usage of admixtures and the quantity of cement.
