causes and solutions of steel pilingup in wire rod causes and solutions of steel pilingup in highspeed wire rod rolling mills? the phenomenon of steel pilingup occurs during rough rolling and medium rolling of highspeed wire rod mills, which can be divided into steel heaping at the head, middle and tail of the rolled piece. specific reasons and solutions are as follows 1.

rod mills, how they function mine engineer.comrod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. for an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. the rod charge must be maintained in good working condition, and broken and worn rods must be removed.
