Impact mill
The other class of mills are "attrition" or grinding mills. Impact mills pulverize the material upon impact. The feasibility of impact mills was greatly enhanced by the mechanization and engineering of the Industrial Revolution. Prior to the industrial revolution, milling was primarily done by attrition or grinding the material between two surfaces. Attrition milling continues to be the dominant milling class, particularly in the milling of agricultural products (i.e. grain into flour). Roller mills and In this study, a drop-ball experimental setup was developed to demonstrate the impact process of grinding media on ore particles.

Constrained impact or abrasion is useful for composite formation or mechanochemical reactions. Roller and centrifugal roller mills have a high capacity, while being characterized by a lower energy Jet mills (also called air jet mills) have a special feature: they do not need mechanical grinding tools. Instead, the particles are crushed and ground in a gas stream by Jet Mills

Choosing the Right Grinding System for (Processing) Pigments
Rotary impact mills are used for fine grinding soft and medium hard materials. The typical fineness area for the median particle size is between 20 and 500 µm. Circumferential speeds of between 25 and 150 m/s are achieved. A version can also be offered in a counter rotating operation with up to 250 m/s.Top 5 product-specific milling technologies used in industrial applications Processing Magazine.

Production and utilization of fuel pellets from biomass: A review
The biomass size reduction occurs due to impact, compression, shear, and abrasion/attrition. In case of impact and compression, force is applied to materials instantaneously (as in ball mills, hammer mills). Whereas, in case of shear and attrition, energy is transferred during a longer contact time (as in knife mills, attrition mills).T1 The impact of processing on allergenicity of food. AU Mills, E.
