ABSTRACT In order to evaluate the sintering characteristics of polydisperse TiO2 and SiO2 fractal agglomerates consisting of nm sized primary particles nanoparticles the change in size distribution of agglomerates in a heated pipe is measured using a differential mobility analyzer and a condensation nucleus counter Change in the structure and the primary particle size of the agglomerates Sinter plants agglomerate iron ore fines dust with other fine materials at high temperature to create a product that can be used in a blast furnaceThe final product a sinter is a small irregular nodule of iron mixed with small amounts of other minerals The process called sintering causes the constituent materials to fuse to make a single porous mass with little change in the chemical
