Grinding Media 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.
Soft and tacky polymers can be ground at ambient temperature in the presence of a grinding aid in an atttrition mill having counter-rotating grinding elements operated above a minimum tip speed (170 m/sec) and at a throughput of more than about 90 kg/hr, the amount of grinding aid, which can be either organic or inorganic such as calcium carbonate, being about 5-20% based on the weight of polymer.
Size Reduction by Grinding as an Important Stage in Recycling 275 for example, multi-edge grinders characterized by low energy consumption, low noise level and good repeatability of grain classes [4, 13]. Cutting between two cutting edges is widely used in cutting mills, in particular for grinding of plastics and cross-linked elastomers [48, 3].
The use of liquid nitrogen to chill the pellets enables more effective size reduction. Cryogenic grinding can be mechanically difficult, requiring expertise to manage moisture, clumping and other important quality elements. Why use cryogenic grinding: Some polymers require the use of cryogenic grinding in order to reduce the particle size.

Keep in mind that no single mill will grind large particles to a very fine size efficiently by repeating or prolonging the process in the same unit. A specific type of mill (with fixed media, operating conditions or equipment parameters) is most efficient in grinding a particular material with a cer-tain feed-size range.
