In the stirring technique, we speak of homogenization or blending when there are two not (fully) equal liquids are mixed, with the aim to make one homogeneous mixture of.
In the mixing of granules, powders or solid in a liquid, one speaks of suspending. The purpose of the process can be to prepare a slurry. The creation of a suspension is a process that is very dependent on substance, in particular if the solid is not easy to be humidified.
By suspending the solid substance is usually dosed at the liquid surface and distributed by stirring into the liquid mass. In addition, the solid can be lighter or heavier than the liquid. Also, it is possible to use a solid, without going to float or settle, by homogeneously distribute the liquid mass.
