The falling coal slurry meet the high temperature (900 960 °C) of furnace and experience drying, agglomeration, volatilize, thermal explosion, burning and falling stages.
When the moisture content of the sawdust exceeded 33 and 54 wt% on a dry basis, agglomeration and channelling occurred in the mixtures of sawdust and glass spheres, with sizes 0.322 and 0.516 mm, respectively.
The differences in the morphology of the CNFs produced with different processes come from the different raw materials and the different mechanisms of fiber formation, such as deposition, drying speed (agglomeration speed), spinning speed (molecular orientation) and so on.
During the advance of drying, presumably the agglomeration of graphene oxide sheets precedes the deposition of more soluble species which accordingly may be dissolved by rinsing with water after the drying.
Dry granulation is an agglomeration process used to produce size-enlarged particles (granules), improving the handling properties of powders such as flowability.
Only spray dried nanosuspension redispersed to original nanoparticles, while particle agglomeration during freeze drying prevented sample redispersion.
The agglomeration tendency of dry pharmaceutical mixtures containing various concentrations of Xylitab®100 (Xylitol), calcium carbonate precipitated (CCP) and magnesium stearate (MgSt) was evaluated statistically as a function of mixing time.
It has also been reported earlier in TEM analysis that for nanoparticles, coalescing, attachment, rotation, and agglomeration on a dry substrate can happen at temperatures much lower than the melting temperature of a bulk material[14].
Large-scale and free-standing TiO2 nanowire arrays were liberated by selectively removing the aluminum substrate and AAO template via a wet etching process with no collapsing or agglomeration after the drying process.
These could be linked to the agglomeration effect of the dry nanosilica during mixing.
