The main advantage of the attritors over the other types of mills is that the powder input is used directly for the agitation of media to achieve the milling effect (it is not used for rotating or vibrating the milling chamber) (Klimpel 1997). These mills are well-scalable and can run in different modes—batch, circulation or continuous one.Web
اقرأ أكثرMills: What are they? How are Mills used? Advantages
A mill is a machine that is used to break down solid materials into smaller pieces by cutting, grinding, or crushing. The process of milling includes the use of force that acts on a material to tear it apart and reduce its size. Milling improves the performance of ingredients, and the products made from them.Web
