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.The second major component in the production of cement is the cost of raw materials. The primary raw material that’s used is limestone. Raw materials account for 30%–40% of the cost of sales.
