The computer enters materials limestone, clay, iron powder, mineralization agent of chemical composition and coal industry analysis data, raw material moisture data conditions, then enters laboratory, after the formulation of the requirement automatically formula calculation, obtained with linear programming limestone and clay and iron powder materials such as the best ratio, get various raw chemical control target. During production, every certain time take a raw samples(general average sample for 1h), presser will representative sample producer after raw, send into analyzer for analysis, Get the analysis automatic (or through the keyboard manual) access control inside machine, at the time, the control machine will be required control target parameters and measured parameters to compare, and then enter ingredients adjust algorithm, the new package packages output baiting ratio. In mill load control system, operators on the basis of mill characteristics of electronic ear control decibels set number, in the certain control cycle(general 5-20min), after the control machine measured to be representative of electronic ear measured values, compare the target parameters with the measured parameters, then into load adjusting algorithm packages, the package will output new production increment. Control algorithm ensure mill filling quantity stability in setting the mill sound range, will not appear the abnormal condition phenomenon such as for material easy grinding sex, water changes in empty grinding, full grinding and so on. When the control machine to get a new production and new blanking ratio, according to multiplication principle, get all kinds of raw material new given flow. It uses the self-adaptive method between the control machine and the measure balance, makes communication interface of each channel anastomosis. The above process ensures the high quality, high yield in raw.
