    Hi Noel, A good machine shop in your area that has a precision
    grinder should be able to resurface your mill rolls. A lot will
    depend on how the rolls are made. Typically items like this are left
    with centering holes in the ends of the shaft. If these are present &
    not damaged the rolls may be mounted in a grinder & reground. The
    amount that must be removed is dependent on the deepest dent in both
    rolls. The both rolls must be ground to this level. 

    If the grinding needs to go below the hardened level (if the rolls
    were case hardened) they'll have to be rehardened. The folks at the
    machine shop will be able to answer this question as a result of the
    grinding. 

Dave
