Jul 03, because of this, the rod mill can effectively reduce 1″ feed size to 10 mesh or finer in open circuit. the voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu..
Jul 19, the rod string's stretch in table 4.1, column 4, of api rp 11l, gives elastic constants (e r) for sucker rods that can be used to indicate rod load. the top rod in the bottom section normally has the highest stress in the string because it has the smallest cross-sectional area. this is because it has to support the weight of the rest of the small-diameter rod load, the pump and the very large fluid load on the gross seating nipple area. the weak point in the string is this.
