Efficient Mechanical Transport SystemsCosts & Benefits
|Parent Process: Raw Material Preparation|
|Energy Savings Potential||
2.0 kWh/t-raw material can be saved.
In a Japanese plant (of 300 tpd capacit) energy used for raw material transport was reduced by up to 80% - depending on the distance. (APP, 2010. p. 75)
In Indian context this technology is reported to provide savings in the range of 0.6-0.8 kWh/t material/100m (with typical energy consumption of around 0.41 kWh/t-100m).
|CO2 Emission Reduction Potential||
For Chinese context, reductions are estimated to be 1.58 kg-CO2/t-raw material (assuming 0.79 kg CO2/kWh electricity)
Costs are estimated to be around $2.2 per annual ton of raw material processed.
In India, implementation costs are reported to be around 0.5-0.7 million, or around $20 000 per t/h capacity, depending upon the capacity.
Efficient Mechanical Transport Systems Publications
The U.S. Environmental Protection Agency’s (EPA) energy guide, Energy Efficiency Improvement and Cost Saving Opportunities for Cement Making, discusses energy efficiency practices and technologies that can be implemented in cement manufacturing plants. This ENERGY STAR guide provides current real world examples of cement plants saving energy and reducing cost and carbon dioxide emissions.
This Cement technologies booklet was compiled by the APP Cement Task Force (CTF) through one of its activities to help its member countries share information on all available energy efficient technologies generally used in the world’s cement industry. The document offers a comprehensive compilation of commercially-available energy efficient technologies used in the cement industry.
