摘　　要：建立了叶片作用于煤粒的力学和速度方程,分析了滚筒结构与运动参数对轴向输煤力和输煤速度的影响,并根据螺旋滚筒的装煤要求,导出了滚筒的临界转速和极限转速的表达式,指出了滚筒转速的控制范围和选择原则。The dynamics and velocity equations of the vanes acting on the coal particles are established.The influences of the drum structure and motion parameters on the axial conveying coal force and velocity are analyzed. According to the requirement of loading coal of the spiral drum, the formulas of the critical velocitY and limit velocitY of the drum are deduced, and the control range and selection principle of the drum rotation speed are put forward.
