Roller-grinders have the ability to break down products to a consistent particle size without over-processing the material or creating too many unwanted 'fines' that diminish the quality of the finished product The key difference between a roller-grinder and a roller-mill is that a roller-grinder has the ability to run each roll in a set at a different speed This differential between
