Particle size reduction is a crucial initial step in the production of countless end products across all manufacturing industries. Think of wheat that needs to be ground in the production of flour, or rocks and rubble that must be crushed in order to make sand, and pharmaceutical ingredients that need to be finely milled for incorporation into drugs.

Updated: Apr 29, 2021. Today's roller mills are an essential part of the American food production chain. Modern flour production depends on the use of grain roller mills to reduce wheat berries into flour. In addition, roller mills are vital to the processing of other grains, including the most important grain in the US today: corn.

The production of sand fillers is simple because it includes, at most, only washing and classification into grades differing in grain size. Because sand has a negligible degree of porosity, it has an extremely low specific surface area in the range from 40 to 160 cm 2 /g. The material usually contains more than % SiO 2, with absorbed water being at a negligible level (%).
