A Comparison of Iron and Steel Production Energy Use and

Production of iron and steel is an energy-intensive manufacturing process. In 2006, the iron and steel industry accounted for 13.6% and 1.4% of primary energy consumption in China and the U.S., respectively (U.S. DOE/EIA, 2010a; Zhang et al., 2010). The energy efficiency of steel production has a ...

Ball Mill & Roller Press Systems for Cement Grinding Process

With the invention of V-type separator, the combined grinding system composed of roller press and ball mill has been developed to further reduce the energy consumption of the cement grinding process. In this system, the ground materials from the roller press is first processed by the separator and divided into two parts: the coarse part and the fine part.

Reducing energy consumption of a raw mill in cement

Cement production in the world is currently about 1.6 billion ton per year. About 2% of the electricity produced in the whole world is used during the grinding process of raw materials. While total electrical energy consumption for cement production is about 100 kWh/ton of cement, roughly two thirds are used for particle size reduction.
