Dust emission from cement kilns can be a serious nuisance. In populated areas it is usual and often compulsory to fit cyclone arrestors, bag-filter systems, or electrostatic dust precipitators between the kiln exit and the chimney stack. Modern cement plants are equipped with elaborate instrumentation for control of the burning process. Raw materials in some plants are sampled automatically ...

Effects of construction dust on humans and environment

Dust at a cement works can be generated from the raw materials used in production (limestone, shale, coal and so on), or can occur as 'fugitive' dust on the hard surfaces and roads of the site. Several measures are in place to reduce the possibility of dust emissions escaping from raw materials during their loading, unloading and storage.

Cement - Cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
