The mill grinding, or respectively the production of bread, flour, semolina, steam etc., is the exception in the grinding technique. Because the qualitative requirements for the roller carriage, as well as for its control, are very high, comparative to paint roller mills and others.


roller mill operator can control the particle size by widen-ing or narrowing the roll gap. For most roller mills, the roll gap is automatically adjusted through a PLC that's pro-grammed to change the gap to match the specs for a new product or batch. This allows roll gap adjustments to be made in just seconds while the mill is operating ...
