Cement Industry » Engineered Hardfacing Solutions To Fight
The cement industry is an energy intensive and significant contributor to climate change. The major environment health and safety issues associated with cement production are emissions to air and energy use. hauling, crushing, screening, stockpiling, and storing .According to the Department of Energy, cement production accounts for 0.33 of energy consumption in the U.S. The current level is low compared with other industries, such as petroleum refining at 6.5 , steel production at 1.8 and wood production at 0.5 .[i] [i] Portland Cement Association, Briefing Kit, Sustainable Development,.Nonetheless, it is recognised that most of the embodied energy of concrete is used in the cement production for crushing, grinding, rotating the kiln, etc. Annually, at a European cement plant, the power consumption and the required thermal energy were, on average, 117 kW h t of cement and 3.75 MJ t of clinker, respectively (WBCSD CSI, 2013).The cement production processes mainly include raw material crushing and storage, raw material proportioning and grinding, clinker calcination, clinker grinding, cement packing, etc. Portland cement is the most widely used cement in our daily life. It is made from a variety of raw materials, typically sand, iron ore, clay, gypsum, limestone.
