Emerging and competing technologies for particulate control in cement plants

The global cement industry handles billions of tons of dusty material (raw meal and cement) each year and does a good job of keeping dust out of the atmosphere. Over the years, the allowable dust emissions from cement plants have become lower and lower. This paper discusses and compares the different methods of removing dust particles from the exhaust gases of cement processes. It is focused on the removal of solid dust particles from the vent systems of cement kilns, raw mills, clinker coolers, finish mills and finish mill high efficiency separators with emphasis on the largest dust collector in the plant: the kiln and raw mill dust collector.
