将连续混炼过程的有效比能耗分为升温、混炼、脱挥和建压比能耗,并提出了计算各项的一种方法。用该方法对不同机型、不同规格、不同加工对象的连续混炼机的比能耗进行了分析。结果表明,在多数连续混炼过程中,升温比能耗在总有效比能耗中所占比例都较大,建压比能耗所占比例都很小;原料热物性是影响有效比能耗及其构成的根本因素;当原料和混炼产物质量确定时,连续混炼机的螺杆与机筒结构、螺杆直径、产量、混炼工艺等都会影响有效比能耗及其构成。
In this paper, the effective specific energy consumption （ESEC） of a continuous mixing process is divided into four portions, i.e. specific energy consumption of heating-up （SEC.H）, mixing （SECM）, venting （SEC_V） and pressurizing （SEC.P）. A method for calculating ESEC and its portions was proposed： ESEC and its portions of continuous mixers which are different in machine type, specification and processed materials were calculated and analyzed. The results show that; 1） for most continuous mixing processes, SEC.H has a very high ratio and SECP extreme low one in total ESEC. 2） thermo-physical properties of raw materials are the essential factor that determines ESEC and its portions. 3） under the conditions of same materials and comparable mixing quality, screw and barrel＇ s geometry, screw＇ s diameter, output and process parameters of continuous mixers will impact ESEC and its portions.
