Roller Mill | Contact us for your Solution | Dinnissen
A roller mill uses two rollers that rotate against each other. The principle of the roller mill is that the rollers are close enough to each other so that no 'whole products' pass through, but far enough apart to ensure the product is not completely crushed. The distance between the two rollers can be determined per product and desired result.
