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.

Abstract: The invention describes a new type of automation for a roller carriage. The amount of product conveyed to the roller carriage is constantly subject to fluctuations, and is determined by a mechanical probe. A corresponding signal directly activates a pneumatic valve, and control pressure adjusts the instantaneous performance of the grinding rolls. The pneumatic valve has a so-called zero position, and becomes a follower control device by means of servo-media and the adjusting mechanism of the performance-dependent elements in the roller carriage. At the same time, the control pressure in the pneumatic valve can start and stop the grinding rolls.

Abstract: A knife scraper for rotating drums, particularly for the drums of a cylinder mill, which exhibits a knife beam (5) in which the knife (3) is mounted as well as a counterweight (12) for pressing the knife (3) on the associated drum (1, 1'). In order to make it especially simple and quick to adjust the knife (5) while simultaneously keeping the installation costs and manufacturing costs low and to make the knife (3) essentially self-adjusting in normal operation according to the invention, several mechanical tension elements (11-15) are provided along the length of the knife (3) by means of which by slightly elastically bending the knife surface (F) extending beyond the knife beam (5) the cutting edge (4) of the knife (3) can be pressed against the drum (1, 1').

Abstract: Apparatus for grinding cereal grain involving the controlling of grinding forces between a pair of cooperating grinding rolls, by determining the actual grain receiving gap between the rolls during rotation thereof and regulating the gap in accordance with a preset desired dimension. A pair of parallel grinding rolls are mounted for movement of one roll relative to the other in a generally radial direction. One of the rolls is yieldingly biased toward engagement with the other roll. Adjustment mechanism is operative to limit movement of the bias roll toward said other roll and to establish said preset dimension or gap between the rolls.
