High-Speed Impact Mills, such as hammer mills, cage mills and pin mills rely on the rotating speed of the hammers/pins and classifiers or screens to control the particle size of the materials. A variation (in some pin mills) is the counter-rotating two-rotor assembly, spinning in opposite directions.Web
Fine impact mills with air classifiers. Because the grinding elements and an air classifier are integrated into a single machine housing, this type of mill is known as a classifier mill. With classifier mills it is the integrated classifier that controls the product fineness and not the speed of the grinding rotor. Classifier mills thus offer ...Web

Pin Mills use shearing and impact methods; however, with a faster tip speed of intermeshing pins when compared to a Hammer Mill. Centrifugal force brings the particle sizes to the grinding chamber's periphery for collection or further processing. The milling process will produce particle sizes down to ultra-fine micronized sizes +/- 10 µm.Web

Hammer mills are whole purpose machines that are designed to crush, grind, and mill material. As the name suggests, the purpose is served by grinding material by small hammer blows. The history of hammer mills is quite old, as the first invention was made in 488 AD. Hammer mills are used for material processing in the food, …Web
rial is rejected by the classifying wheel and returned to the grinding zone for further comminution. The fines pass through the classifying wheel and exit the mill. The cut point, i.e. the product's maximum particle size is a function of the classifying wheel speed, which can be infinitely adjusted even during ope-ration. importAnt feAtures ›Web
