ABSTRACT:
At a milling machine to work ground surfaces, with a machine frame, a milling drum supported at the machine frame, at least one transport device arranged at the machine frame which accepts the milled material from the milling drum, as well as with a suction device for the air polluted with dusts and vapors, whereby the milled material on the at least one transport device is enclosed by a channel, the suction device is connected to a rear channel section of the channel in the direction of the material transport and sucks off the air polluted during milling at the milling drum and in the rear channel section essentially in the direction of the material transport, it is provided that the suction device consists of a suction ventilator, a separator device for solids and a suction channel which is connected to the rear channel section, that the suction ventilator is arranged downstream of the separator device, and that the suction device disposes of the separated solids onto the transport device in a forward channel section in the direction of the material transport or into a collecting device, and the suction ventilator blows off the cleaned air into the environment.
