该机电气控制系统:采用PLC电脑控制，分手动档和自动档。混炼过程可分三次投料，分别设有三档选择开关，三次投料分别由数显时间继电器计时，用户可以根据生产需要自行设定时间长短，直观清楚，便于操作，系统安全可靠。

       Internal mixer prime task part: Rotor and mixed iron-smelting room. Their performance and the quality quality has decided the internal mixer performance height and the life length。 1.Our company and the Qingdao Scientific and technical university Mechanical and electrical Engineering college cooperation, improved the rotor bank or ridge between fields body structure reasonably （spiral angle, bank or ridge between fields body length and section shape three parameters）. Thus enhanced the internal mixer mixed iron-smelting effect effectively, reduced compared to the traditional internal mixer has built up the rubber time about 1/4, corresponding saved the electrical energy, enhanced the output.  2. rotors and mixed iron-smelting room life lengths by substrate material and active face ultra hard chrome-plating level as well as Gao Moqu alloy layer decision. First increased the built-up welding internal mixer special-purpose flinty antifriction metal in Gao Moqu, and in plates the 0.20mm thick hard chromium level with the sizing material contact active face, compared to domestic other company product coating accumulation one time, thus the service life obtains the big extension. The substrate material has used the low-alloy structural steel, both guaranteed the intensity and to guarantee the resistance to wear. The equipment performance obtained the distinct enhancemen。
