Operating costs are also estimated for a two-shift, 16-hour-a-day schedule. This reduces cost per ton of output by 12 to 20 percent. Total costs range from $3.93 per ton in the 50-ton plant to $13.18 per ton in the 6-ton model. Practically all savings by the two-shift operations are due to reduced fixed costs.
