摘　　要：搅拌理论与设备的研究涉及机械工程与建筑材料两个学科,只有将两者有机结合起来,才能较好地解决搅拌机构与混合料相互作用过程的机理分析问题及工程应用问题。介绍近20年来搅拌理论及其设备的研究进展,建立搅拌过程的数学模型,得到搅拌曲线、新的搅拌概念、搅拌设备的优化目标和方法,以及搅拌功率的计算方法;提出振动搅拌理论,研制出振动搅拌设备,以及双螺带、双螺旋、双排叶片等节约型搅拌设备。针对完善搅拌设备的评定指标提出:随着对搅拌过程的研究从宏观向微观发展,除目前国标规定的宏观匀质性指标外,建议增加强度、含气量及耐久性等指标。The mixing theory has to be combined with mixers study so as to solve prob-lems in mutual action and application in a better way out. The text introduces study progresses in both mixing theory and the mixer for the recent 20 years in areas of mathematical model, mixing curves and new concepts, mixers optimal indicators and how to optimize, as well as how to calculate the mixing power rate, before put forth vibratory mixing theory, vibratory and economical mixers so made, along research and development tendency in this field, thus providing per-feet indicators for evaluating the mixing equipment, beside a package of proposals for an economical mixer with dual screw conveyors, dual screws, and dual rowsof blade, for indicators of even mixture quality, plus those for strength, air con-tent, and durability.
