There are several industries that make use of limestone As such powdered limestone is used in the textile paint paper rubber glass and plastic industries amongst others They are mostly used as fillers Apart from this it is used in the steel industry for the production process where limestone is used to remove impurities
WhatsApp
— Limestone is used in poultry diets as a calcium Ca source Feed formulation is often based on an estimate of limestone Ca content or less frequently wet chemistry analysis
WhatsApp
— The particle size of limestone slurry or limestone slurry fineness directly impacts the process of flue gas desulfurization and the gypsum quality and the reaction efficiency of the slurry and flue gas is improved with the decrease in particle size; however over grinding may lead to increased energy consumption [7] [8] Currently
WhatsApp
It is a process of excavating and exploiting the raw materials underground for any use Limestone for example the key raw material can be mined in the quarries with compressed air drilling and subsequently blasting with explosives They are used for size reduction of hard to medium grain size and sometimes for wet and sticky material
— grades of limestone for use in steel plants shall be as laid down in IS 1387 5 GRADE DESIGNATION Flux grade limestone shall be of the following two grades as given in Table 1 a For steel making — Grade 1 and b For iron making — Grade 2 Table 1 Chemical Composition and Size Requirements Clauses 5 and 7 SI Constituenta
WhatsApp
— The change is that the specification adds up to 5% limestone The biggest difference in production is that the limestone is added to the clinker blend before grinding Because the limestone is softer than the clinker it will grind preferentially resulting in a cement with a better particle size distribution with less energy
WhatsApp
— Portland cement is one of the most used materials on earth Its annual production is responsible for approximately 7% of global carbon dioxide CO 2 emissions are primarily associated with 1 the burning of fossil fuels to heat cement kilns and 2 the release of CO 2 during limestone calcination One proposed
