From table 20 as seen, no matter whether the variance of two processing equates that its average all has marked difference; (6) in sum, it is best processing as can be known 1-2-1, to the throwing filler point of 6 observed values processing 1-2-1, time average such as the following table 21 of throwing oil plant point and off-take point:

Thereby the time controlling value that is optimized is: 15 seconds throwing fillers, 90 seconds throwing oil plants, 165 seconds discharges. Optimize rules by this and produce comparable former traditional handicraft (average wastage in bulk or weight energy 22.15KWH, 176.5 seconds total times) is produced, every crowd of elastomeric compound conserve energy 0.28KWH, during joint 11.5 seconds; (7) model is carried out the suitability verification and pass through, above-mentioned optimum results can be accepted.
Embodiment 3: optimize calendering process, shorten mixing time, reduce energy consumption. (1) use mixer mixing process Automatic Optimal monitoring system of the present invention to gather the relevant parameters of 64 batches of elastomeric compounds; (2) adopt each processing of two factors, two levels to repeat 8 times factorial test. Factor A, B represent respectively the time of throwing oil plant point and off-take point, its horizontal division such as following table 22:
