Mill Grinding Of Polymers

Particle Size Reduction | Disputanta VA | Ancos

Some polymers require the use of cryogenic grinding in order to reduce the particle size. Given certain polymer properties, some materials do not behave in a way that is necessary to achieve desired particle size reduction results without being chilled. For example, crystalline materials would melt from the friction of the grinding process if they were not cooled prior to entering the mill. Other materials may oxidize …

Pigment Grind: How to Efficiently Adjust the Fineness

10.11.2015· In the industry, the fineness of grind is generally achieved with a 2-step process. First, developers and producers of paints use a dissolver to reduce the particle size of their pigments and fillers to a certain degree of fineness. Then, when needed, they additionally use a pearl mill to further separate the solid particles from each other.

How to disperse and stabilize pigments

After the wetting stage, it is necessary to de-aggregate and deagglomerate the pigment particles. This is usually accomplished by mechanical action provided by high impact mill equipment. In the grinding stage, the cohesive forces inside the agglomerates have to be overcome. Energy is added to the system and therefore smaller particles (with a larger interface to the resin solution) are formed. This results in …
