Optimizing the Mixing of Powders Into Liquids – Dust

2012-10-22  The first issue to consider in the mixing of powders into liquids is the dust created. Pouring powders onto the liquid creates significant dust if the pouring process is not done within a contained environment. The dust escaping into the work environment puts workers at risk for respiratory issues and possible explosions, as well as creates significant product waste. Dust accumulates below and on the

Powder Dispersion Dispersing Mixer Equipment and

2021-8-11  Two problems arise when dispersing difficult powders. First, the powders float, resisting efforts to wet or disperse them. Second, the powders clump into impenetrable sticky masses or “fish eyes” (powder lumps with a hydrated skin and dry core). Conventional in-tank mixing leads to long batch times, powder buildup and waste during tank cleanup.

In bulk powder processing, dispersion is the process of achieving even particle distribution of heterogeneous materials. Some powders, however, are poorly dispersible and have a tendency to clump together. In order to create a homogenous blend of such materials, many dispersion processes include intensive deagglomeration as part of the dispersion process.
