We are in the development of fine aluminium hydroxide powders. we are targeting the particle D50 to be around 1 to 2 Microns by sedigraph method. We will be drying the aluminium hydroxide cake ( 50 % moisture) in oven drier at 80 Deg. C overnight. after drying, we are gettting very low bulk density in the product. The tapped bulk density is around 0.35 to 0.4 g/cc. But we wanted to have tapped bulk density of 0.55 to 0.65 g/cc. Please help me with this. ■
