PROBLEM TO BE SOLVED: To provide a cyclone dust collecting device which is a device for removing dust generated by crushing or the like, capable of preventing environmental deterioration of the surroundings due to the scattering of dust and has a simple and economical structure. SOLUTION: The dust 3 generated from a material 1 to be crushed transported on a conveyer 2 is sucked from a dust chamber 5, introduced into a dust collecting chamber 7 and led to a cyclone 11 through a duct 10. The dust 3 introduced into the cyclone 11 falls down with the action of centrifugal force, made to be mud by water supplied from a pipe 15 through the adjustment by a valve 16, falls down to a water tank 14 and held. The mud falls down on the conveyer 2. The separated air which is lighter than the dust, is introduced on the conveyer 2 through the duct 21 in the same manner as the mud. The flow of the dust 3 forms a closed loop and circulated and discharged outside the cyclone dust collecting device.
