influences the particle size of the hydrated lime—and, therefore the reactivity of the slurry Simply put, the closer the slaking temperature is to the boiling point of water, 212°F (1000°C), the finer the particle size, the greater the surface area, and the more reactive the slurry Ideally, it should also not exceed this temperatureThis lime has a more varying particle size than the four year old earth slaked lime, but generally it looks more like earth slaked lime than wet slaked lime (figure 7c and d) The wet slaked lime (figures 7c and d) has particles in various sizes The influence of particle size and structure in hydrated L4 had the highest Fe2O3 composition (055%), and its percentage is 45% higher than the maximum standard composition of Fe2O3 in a produced quicklime (Hwidi et al, 2018)Particle size distribution of CaO sample ResearchGate2016年12月8日 Ag limestone can be calcitic or dolomitic (contains at least 6 % magnesium) and regular ground and finely ground depending on particle size There are three factors that determine limestone quality: chemical composition, particle size and moisture content The chemical composition determines the materials acidneutralizing valueAgricultural Lime and ByProduct Limes Plow Points
