In present – day cement manufacture, with due regard to the possibilities of the reduction machinery employed, crushing is taken to mean reducing the particle size between about 80 and 20 mm. This crushed product is further reduced by grinding to fineness below about 0.2 mm size, in which condition it is called raw meal and is ready for feeding to the kiln.

2011.8.25 By Patrick Murray August 25, 2011. Cement producers have faced a significant rise in energy costs with the introduction of dry-process kilns, with a record average consumption of 100-200 kWh per ton of cement, according to the 2009 Cement Plant Operations Handbook. This complex challenge, coupled with rising fuel and energy

2015.8.20 Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they
