ABSTRACT:
A device for normally maintaining a predetermined, set spacing between two associated flaking rollers of a flaking mill and for allowing the two rollers to spread apart from one another if unflakable material of a size larger than the predetermined, set spacing between the two rollers is fed therebetween. A hydraulic piston having a manually adjustable stop is mounted between the two rollers so as to maintain a predetermined, set spacing between the two rollers. A gas piston is associated with the hydraulic piston to act as a shock absorber if any unflakable material of a size larger than the predetermined, set spacing between the two rollers is fed therebetween to allow the two rollers to spread apart. The gas piston is preloaded to a pressure substantially greater than the pressure normally required to flake the material being fed between the two rollers.
