Raw Mill Optimization Module The Raw Mill Optimization option controls both the temperature, the feed rate to the mill and the separator speed in order to achieve the required throughput for kiln. Where starting the mill requires dampers to be moved, to change gas flow paths, the module will also respond to these effects to keep the system stable.

There are a number of fan types: impeller, axial, centrifugal, Sirocco, etc. all of which have individual benefits (volume, pressure, speed, power, efficiency, etc.) but all of them will shift gases at the same rate based upon the input power.Differences such as efficiency or flow rate occur in the type of fan due to particular design advantages that favour one characteristic over another.

The mill calculates the average value of the relevant alloys for a defined period (usually 1 month) before the date of the calculation. Some mills even calculate the average values on a daily basis to provide daily alloy surcharge prices. The average value of nickel and molybdenum follow the stock prices on the London Metal Exchange (LME).

Once you get the machine time you can calculate the cost by multiplying it by the amount per hour charged. for example it the volume was 25 & there were 2 details then it would be ((25 x 2)/10) x $95.00/hr. = $474.00 The only thing I cant figure out is how to get the cut volume.
