The procurement and fabrication of the two rolling mill rolls used similar processes with several differences for each roll. The machining/precision grinding of the two rolling mill rolls were physically similar but had differing pilgering roll orientations for the precision cold working of the difficult to process nuclear cladding materials.
To get rid of pulp and rocks in the charge, a mill grind-out (no ore feed) of 10 to 20 minutes is also performed before mill inspection or relining. The complete grind-out is required to obtain the accurate ball load measurement or the percentage by volume of balls in the mill. This is usually performed soon after a crash stop.
