1 天前 Emissions - aside from CO 2 emissions, the cement industry's main emissions are NO X, SO 2, and dust. Dust abatement has been widely applied for many years and SO 2 is a plant-specific issue. NO X abatement has taken off in recent years with more than 100 selected non-catalytic reduction (SNCR) installations in the cement industry. Some plants ...

2018-6-11 limestone produces dust which is re-leased into the atmosphere during blast-ing. Quantities of such dust, which is released intermittently, have not been reported. There is little that can be done to confine this dust as long as blasting is the means of shattering the rock loose. Often the noise produced 32 is as objectionable as the dust. For-

2020-5-1 They produced a data-set that included most of the dust-producing construction activities executed at a construction site (i.e., cement mixing, drilling, excavation, sanding, cutting, etc.). A total of 777 samples were taken for personal exposure of a full working day and a specified activity.

2012-9-20 “The most important priority for cement companies with regard to employee well-being is the assurance of occupational health and safety, both for workers and contractor personnel. The cement industry is not nearly as advanced as some other heavy manufacturing industries in the implementation of occupational health and safety management systems.

2014-2-21 Dust is emitted from storage, crushing, grinding and pyroprocessing in cement plants. It is the industry's most obvious pollutant, since you can actually see it. It can cause respiratory problems. Some of the earliest cement plant emission regulations were for dust. The German Cement Association (VDZ) set up a dust committee as early as the 1930s.

2017-12-20 Cement industry’s focus is on reducing ambient particulate emission by reducing the mass load emitted from the stacks, and other sources up to less than 0.2 kilograms of dust per metric ton (kg/t) of clinker using dust recovery systems. NOx emissions are controlled using proper kiln design, low-NOx burners, and an optimum level of excess air.
