Question

What are the differences between solid mixing and liquid mixing?

Answer 1

Solid mixing:

• Solids are said to be mixed with solids when they are combined with other solids, liquids, or gases.
• There is no flow current produced by the mixing of particles.
• Dry solids have a strong ability to mix.
• Blenders and mixers are used to mix solids.

Liquid mixing:

• Liquid mixing may be characterized as the blending of different liquids.
• A flowing current is produced when liquids are mixed together.
• Liquids have a lesser mixing power than solids.

Differences between solid mixing and liquid mixing:

Solid mixing	Liquid mixing
Solids mixing is comparable to mixing low viscosity liquids.	Typically, a fluid mix is a combination of liquid and liquid or liquid and gas.
Heavy volumes of particle materials cannot have such currents, hence mixing must be accomplished in another way.	Unmixed material is moved to locations close to the impeller where it is used to mix liquids by creating flow currents.
Dry solids require more force to mix than moist solids do.	Less force is needed to mix and blend liquids.
Solid mixing frequently results in the creation of many clearly distinct phases, each of which may include discrete particles of sizable size.	When a liquid phase has been thoroughly mixed, it is often fully homogenous.
Two samples of "well-mixed" solids had distinctly different compositions.	When a sample of a liquid product is "well-mixed," it has a homogeneous character.
Equipment for mixing and blending solids is built, operated, and designed differently than equipment for mixing liquids.	The design, construction, and operation of liquid agitators are all focused on mixing liquids.
