Top 5 product-specific milling technologies used in,

One of the best size reduction systems for fine pigment grinding is the hammer and screen mill. This pulverizer uses swing-hammers with interchangeable screens to produce a variety of products from 50 to 100 microns. The hammer and screen mill needs less air (less ancillary equipment) than the ACM and is a lower cost option for pigment processing.Mill (grinding) - Wikipedia,A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().Rolling (metalworking) - Wikipedia,Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.
