The continuous conveyor of disc-tube assembly is a new kind of machine transporting powder.The distribution of the volume fraction of coal and the pressure

force on driven wheel and disc-tube assembly was simulated in a cycle.The result shows that the force on the driven wheel and disc-tube assembly is less and steady

and the force on the inner wall of the pip is large.It shows that the amount of material transmitted by continuous conveyor of disc-tube assembly is quite constant

and there is much mechanical vibration and noise in the operation.
