Abstract

In an apparatus for producing milled grain products by means of repeated roll grinding and sifting of specific product fractions, the material to be milled is at least partially guided via double-grinding passes without intermediate sifting. An eight-roll mill is used for this purpose, which eight-roll mill is constructed as a double unit with two roll pairs arranged at a distance one above the other and can be used in quantity in a grain milling system or also in combination with single-grinding passes constructed as four-roll mills. Compared with the use of known four-roll mills, the economic efficiency of a mill is accordingly improved while completely retaining the adaptability of the mill to specific grinding tasks, the quality of the material to be milled and/or the ability to monitor the grinding process.
