ABSTRACT: The double-rotational vertical screw conveyor is a new type of screw conveyor in which the screw and casing rotates respectively in the opposite direction. The mechanism of the device and performance is not fully understood. We analyze its performance such as particle velocity distribution, particle mass flow rate, motor power, transmission efficiency through Discrete Element Method in this paper.
