Particle size reduction of pigments using a small media mill. A small media mill (Figure 10.1) is used for particle size reduction and dispersion of particles in liquid systems. The term 'small media mill' refers to the size of the grinding balls (the medium) used in the machine, generally in the 1 to 2 mm nominal range.

 · Size reduction was found to increase with increasing value of slurry solid mass fraction, until it reached a maximum and then decreased. The use of grinding media of smaller diameter was found to cause higher rates of size reduction and narrower particle size distribution than the use of larger grinding media.

Pin mills are impact mills that rely on the force caused by the continuous impact between the medium and grinding components to reduce the particle size of the starting raw chemicals. During the manufacturing process, individual raw chemicals are weighed per the specified formulation, grouped, and pre-blended prior to the milling process.

 · This allows for the production of a greater variety of byproducts and also can result in improved physical properties in your final product. By contrast, dry milling utilizes no liquid element, and is most frequently used for the particle size reduction of dry materials like powders and granules, or de-agglomerating and de-lumping bulk materials.
