Downwards conveying conveyor e.g. belt conveyor, for mining industry, has impeller whose blades are set diagonally in circumferential direction in direction from rotor base to blade point against driving direction of impeller

摘要

The conveyor has an impeller (3.1) and a turbine wheel (3.2) with respective blades. The blades (4) of impeller are set diagonally in a section in a circumferential direction in a direction from a rotor base (3.3) to a blade point (3.4) against a driving direction of the impeller. The blades of a turbine wheel are set diagonally in the direction from the rotor base to the blade point in the driving direction of the turbine wheel.
