The rolling mill is equipped with a walking beam furnace with a capacity of 125 tons per hour. Blooms are de-scaled after exiting the furnace, and then proceed through a five stand roughing mill, a six stand intermediate mill, and an eight stand finishing mill. Dimensional control is maintained by optical laser gauges and manual micrometer checks.

Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.

This underscores the need for aggressive liners with some mixing and classifying effect, in order to realise maximum mill capacity. High air flow rates alone may not economically achieve the required mill throughput, (i.e. in the extreme case where no cataracting of media occurs, mill capacity will be very low at any air flow rate).4. Conclusions
