2019-12-5The industry uses very powerful machinery with the potential to cause fatal and serious injuries. There are established industry safeguarding standards for two-roll mills, internal mixers and calenders. Many serious accidents take place during repairs or to clear blockages etc. and there must be procedures in place to ensure that
2018-9-26the clinker cooler operation (e.g. Smith and Burke (1998)). None of these studies have used infrared camera-based measurements. Because the cooling step decisively affects the quality of the pro-duced cement clinker, we think that the use of infrared technology in the clinker cooler is an essential tool for process monitoring.
2016-1-4Recently, the vertical roller mill having great grinding performance is widely applied to the raw material grinding process. However, tube mill, which has about 30% poor grinding performance as power consumption, has been still used many existing cement plant. The improvement of this tube mill grinding system is highly expected. Descriptions
