Dry grinding and wet grinding are two different materials grinding methods, which are widely used in industry and laboratory.

Dry grinding

Definition:

Dry grinding refers to the process of grinding and crushing materials without any liquid addition. This method usually grinds the material from large particles to smaller particles by mechanical grinding.

Features:

Operation: No need to add any liquid, simple and convenient.

Product: The end product is a dry powder that is easy to store and transport.

Energy consumption: Energy consumption is generally low, but since there is no liquid medium to reduce friction, more mechanical force may be required.

Dust management: Prone to dust generation, may require additional dust removal equipment.

Scope of application:

Mainly used in mineral, chemical raw materials, plastics, dry feed grinding.

Wet grinding

Definition:

Wet grinding is the addition of a liquid (usually water or other solvent) during the grinding process to help reduce friction between particles and achieve finer particle size and uniform dispersion.

Features:

Operation: need to add media, through liquid lubrication and dispersion, can effectively reduce particle adhesion phenomenon.

Product: The final product usually contains some moisture and sometimes needs to be further dried.

Energy consumption: Due to the lubrication effect of the liquid, the energy consumption is usually lower, and the grinding effect can be better.

Particle treatment: suitable for the treatment of viscous or wet materials, to obtain a more uniform particle distribution.

Scope of application:

Widely used in coatings, cosmetics, food, animal feed, chemical materials and other products requiring a high degree of dispersion and fineness.

Sum up

Dry grinding: suitable for materials that need dry powder, easy to operate, but dust treatment is more important.

Wet grinding: Suitable for viscous or dispersing materials, can improve grinding efficiency and particle size uniformity, but need to deal with moisture and equipment cleaning.

The choice of the two usually depends on the characteristics of the material, the purpose of the end product, and the requirements of the production process. If you need further information about specific applications or technical details, please feel free to let me know!
