Mangalam Cement has halted operations of its kiln line 1 in order to upgrade its clinker manufacturing capacity by 0.5 mtpa. The project is likely to be completed by the end of the second quarter of FY14. The supplies will be sufficient in the interim as it has clinker in stock. The company has one cement plant Morak, Kota, Rajasthan with a capacity of 2 mtpa of cement.
