Roll surface grinder

Apparatus for grinding a roll of a flaking mill, the roll having a longitudinal axis of rotation, comprising:

• a grinding wheel carriage assembly including a swing arm carrying at least one grinding wheel;
• support structure for carrying said carriage assembly and mountable on the flaking mill for engaging said grinding wheel against the roll, said structure including a pair of longitudinally spaced structural members extending generally parallel to the axis of rotation of the roll;
• a shaft carried by said support structure and extending generally parallel to said pair of structural members;
• a motor for rotating said shaft;
• said carriage assembly being mounted on said shaft and one of said structural members for traversing movement along said shaft and one member between opposite ends of the roll;
• a rolling ring drive coupled to said rotating shaft for driving said carriage assembly along said shaft and said one member between opposite ends of the roll;
• and
• an adjusting mechanism for pivoting said swing arm relative to said carriage assembly to adjust the depth of grinding;
• said swing arm including a pair of laterally spaced grinding wheels such that, upon traversing movement in one lateral direction, at least one of said pair of grinder wheels is positionable to grind one end of the roll up to and including the one roll end and, upon traversing movement in an opposite lateral direction, another of said pair of grinding wheels is positionable to grind an opposite end of the roll up to and including said opposite roll end.
