Roller mills: Precisely reducing particle size with ...

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, which al-
