The next graph represents the charge density for the different products derived from limestone. Significant differences are observed. Coarse (d>30um) and fine (d<20um) hydrated lime Ca (OH)2 powders do not acquire the same charge. In particular, the fine powder is less charged, certainly due to the existence of agglomerates.
