The chemistry indicates that this spent refractory is fairly clean. Table I New and spent MgO+C refractory chemical composition MgO+C Al2O3 CaO FeO MgO SiO2 C N2 New 4.40 0.99 0.37
refractorylined furnace, through which the limestone and hot combustion gases pass countercurrently. Coal, oil, and natural gas may all be fired in rotary kilns. (English units) include emission factors for the mechanical processing (crushing, screening, and grinding) of limestone and for some materials handling operations. Section 11.19
crushing and grinding operation 2sizingSizing is the separation of material or product into various fract ions characterised by difference in size. Sizing can be performed by screening or classification. The latter depends on the settling velocity of particles in a fluid (air or water). 3concentrationConcentration may be regarded as
