Roller mill

Roller grain mills are an alternative to traditional millstone arrangements in gristmills.

Two-roller mills are the simplest variety, in which the material is crushed between two rollers before it continues on to its final destination.

Hungarian hard wheat so milled was claimed as integral to the "First in the world" success of the Vienna Bakery of the 1867 Paris Exposition.

Modern era roller mills were re-invented by the Hungarian engineer András Mechwart in 1874, then quickly spread to other parts of Europe and Americas.
