1. A method comprising:
conveying material in a conveying pipe pneumatically by means of suction, a pressure difference or a transporting air flow in a material conveying system, the material conveying system comprising a first input point for feeding a first material, a first conveying pipe, at least one first separator device at an outlet end of the material conveying pipe as well as a partial-vacuum generator, wherein a suction side is connectable via the first separator device to the first conveying pipe, as well as means for opening and closing an access of replacement air to the first conveying pipe, for conveying the material from at least one first input point in the first conveying pipe, to the first separator device, wherein a negative pressure or the pressure difference relative to surrounding pressure is provided by the partial-vacuum generator, whereby a second material conveying arrangement is provided,
wherein the second material conveying arrangement comprises at least one second input point for feeding a second material, a second separator device, a second conveying pipe between the at least one second input point and the second separator device, wherein the separator device of the second material conveying arrangement is operatively connected into medium communication with the first conveying pipe to connect the suction or pressure difference acting in a first pipe-line to act via the second separator device in the second conveying pipe, whereby the second material is conveyed from the at least one second input point in the second conveying pipe to the second separator device where the second material is separated from transporting air flow, and the second material is collected into a collection container of the second separator device.
