| Abstract: | 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. |
