ABSTRACT
Cement manufacturing industry is one of the important sectors of the Indian economy. In view of the growth rate, it is expected that more and more cement plants would come up and also the existing plants may expand their capacities through up gradation/modernization. Usage of extra fly ash, slag etc. is also increasing to make additional production capacity as raw material. Looking to the increasing market demand, most cement plants are making efforts to accomplish higher production levels by adding additional capacities. The environmental concerns in terms of emissions to atmosphere are also rising. Cement plants have made substantial efforts in controlling the stack emissions using most effective control systems like high efficiency pulse jet bag filters in the form of bag houses and ESP for stack, if any. These plants generally meet the environmental standards for stack emissions. In cement industry, the major pollution is fugitive dust or other dust particles like cement dust, airborne dust from raw material handling, kiln feed preparation and grinding process. Therefore, fugitive dust control is necessary. The fugitive dust emission reduction and reuse or recycling of dust is focusing trends nowadays.
