Grinding Media is typically a bead of uniform size, shape, and density. The media is agitated in high concentration with a slurry (or mill base) to be ground. In a small media mill a central shaft agitates the media and slurry. Energy is transferred from that shaft to the nearest layer of beads and from that layer to subsequent layers of beads.

· In order to disperse the pigment to a nano-level, the use of 0.3-0.5 nm grinding media is recommended. Stabilization Due to the increased surface area of the solid particles during the deagglomeration/grinding stage, the pigments that are deagglomerated need to be stabilized in order to avoid issues such as flocculation, color shift, sedimentation and stability loss.

· The proper choice of a wetting and dispersion surfactant reduces the interaction between the pigment particles. The pigment dispersion process can be divided into three stages: wetting, dispersion/grinding, and stabilization. In wetting, it is important to use an additive that can reduce the surface tension of the water, enabling it to penetrate pigment pores thereby wetting of the pigments to ...
Grinding media are the means used to crush or grind material in a mill. It comes in different forms such as alumina oxide balls, ceramic cylinders, or soda lime glass. At Norstone Inc., we offer all types of medias used for grinding, deagglomeration, polishing, deburring, fillers, proppants, spacers, refractory beds and shot peening.

Dispersants permit milling at higher pigment concentrations, causing the more rapid breakdown of particles; at the same time, they will prevent viscosity building up during the grinding process. Finally, they will impart colloidal stability to the finer particles so that they do not flocculate and their full intrinsic color strength is utilized.
During the grinding process, dispersants will adsorb onto the pigment particles and stabilize the particles, preventing re-aggregation and re-agglomeration. By choosing the right dispersant-pigment combination, the stabilization action allows for the preparation of stable pigment grinds with a particle size below 100 nm, approaching the primary particle size of transparent pigments.

These "grinding media" combine the advantages of selective drying capacity, crosslinking into the film, anti-settling and anti-floating effect and compatibility to both solvent-borne and water-borne systems. Such novel "grinding media" can be used to produce
Ceramic grinding media are also suited for use in processes where mixing and dispersing effects play an important role. In the majority of these grinding processes, steatite and alumina are the most common ceramic materials used for grinding balls and linings. CeramTec generally manufactures its grinding balls and linings with steatite.
