摘　　要：提出耦合筛分概念及方法,基于单颗粒物料在平面振动筛分和滚筒式筛分共同作用下的运动学分析,构建了物料耦合筛分的质点运动数学模型;系统分析了振动频率、振幅、筛面倾角、滚筒中心轴转速、筛面倾角、筛面开孔率及物料相对几何特征等因素对耦合筛分效果的影响,进行耦合筛分机整体设计。The concept and method of researching coupling screening were put forward. Based on the kinematics analysis of the mono-particle under the combined effects of a flat vibrating screening and drum sieving, a mathematical model of the particle motion for coupled screening was built. The effectiveness of the coupling screening, which are influenced by vibration frequency, amplitude, sieve surface inclination angle, roller center shaft speed, the screen surface inclination, opening rate, the relatively geometric feature of the particles, was analyzed systematically. The coupling screening machine was designed.
