IMPRESSIVE ENVIRONMENTAL PROTECTION AT MYSORE CEMENTS' AMMASANDRA PLANT The well planned and continuous efforts of Mysore Cements Ltd (MCL) over the years have earned their Ammasandra plant the distinction of one of the environmentally best managed cement plants. Continuous upgradation The plant has a complement of high-tech dust control equipment, such as ESP's, bag filters (mechanical and pulse-jet types) and cyclones, at various sections. These are periodically upgraded to induct latest advances in technology. Thus MCL was the first in India to go for multi-pulse generation hot ESP for kiln exhaust gases. The ESP installed on Kiln No. 3 (see photograph) has a dust collection rate of 8 to 9 tons /hour. New generation microprocessor-based ESP controllers have been installed on Kiln No 4, cement grinding mills and rawmills. Clinker coolers of Kiln No 3 and 4 are provided withEPIC- controller based ESP. Open-type ESP is installed at coal grinding unit. Among other improvements is the use of special type of nozzles for atomisation of water in the pre-conditioning of exhaust gases from Kiln No 4; these help improve the efficiency of the pollution control equipment. Plantation At inception, in 1960 the region was barren without any trees. MCL then began an intensive programme of planting trees in the 280 acres of land belonging to it. As a result, toda:y there are more than one lakh trees/plants in and around the plant, which has transformed the A view of Kiln No 3 in operatipn. The almost nil stack emission owes to the multi-pulse generation hot ESP which handles 3,54,000 m 3 / hr of exit gas. entire landscape. The beautiful parks developed and maintained around the plant and the township are a feast to the eyes of the visitors.
