Roller mills: Precisely reducing particle size with greater ...

distributions in the 100- to 2,000-micron range, a roller mill is the best option. While it does have a relatively high capital cost (for instance, from 50 to 200 percent higher than most hammermills), its ability to precisely reduce particles while using less energy and producing little waste can provide a relatively fast return on investment.

Roller mill - Wikipedia

In the 19th century roller mills were adapted to grist mills before replacing them. The mill used either steel or porcelain rollers. Between the years 1865 and 1872, the Hungarian milling industry upgraded and expanded the use of stone mills combined with roller mills in a process known as Hungarian high milling.
