Cement Manufacturers Association

Industrial Aspects Towards Green Tomorrow with KHD Technology & Efficient Processes India being the second largest cement producer in the world, accounts for over 8% of the global installed capacity. Around 70% of total cement production in India revolves around the top 20 companies. Over a decade, the Indian Industry has spotted uncertainties, increased fuel prices, environment load, sustainability, etc. In view of the relentless requirements of cement industry, as a responsible Partner KHD is steadily delivering and contributing its best for more than 160 years presenting a sterling example in fulfilling its responsibility as a prime technology supplier. Persistent development based on industry needs which mainly focuses on green environment, drives the technology providers to ponder ahead and gear up to impart cement industry with the latest art of technology integrating innovations leading to plan sustainability in the long run. With depleting resources, growing concerns for greenhouse emissions and sustainable practices, KHD with its visionary approach has unriddled that for consistent growth, the base forming principles should be acquired through a sustainable life cycle. High Demand Earlier, the cement manufacturers believed to set up small plants of about 1.5 MTPA max. But now, it’s more towards installing large capacities for clinkerisation say >3.0 MTPA. Factors that stimulate manufacturers to set up a single huge capacity plant rather than opting small capacity plant are due to benefits like low investments, low transportation costs, installation of utilities, energy conservation, etc. Although, huge capacity plants have enough advantages, but some concerns always surface like machine maintenance and reliabilities. KHD with its huge capacity plants has proven that such issues can be tackled by selecting the right machinery which not only meets the environmental requirements but caters to the demand growth also.. Installment of Efficient System The evolvement of calciner series wherein was developed over time for usage of alternate fuels of varying quality and degree. The evolvements were made considering the requirement of industry to use more of alternate fuels than the noble non-renewable fuel sources (Fig 1). Today, focus is on efficient use of alternate fuels up to 90% in desired systems thus decreasing the load on mother nature and contributing towards the “2050 Climate Ambition”. Decreasing thermal energy consumption which is addressed by developing the preheater cyclones and calciner by KHD, to seize radiation losses in the system to protect the environment. KHD furnish proper insulation in preheater and ducts along with special aluminum- based paints to retain the heat within the system and increase the availability for intrinsic processes.
