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.
