Abstract:
1. A method for conveying material in a pneumatic material conveying system, said conveying system comprising; at least one feed point of the material; a separator device having an input port and an output port; a transport container with an input port and an output port; a vacuum pump device having a pressure side and a suction side; a material conveyor pipe having one end connected to the input port of the separator device and extending to the at least one feed point; at least one first conveyor channel having one end connected to the output port of the separator device and an opposite end connected to the input port of the transport container; at least one second conveyor channel having one end connected to the output port of the transport container, and an opposite end connected to the suction side of the vacuum pump device; wherein the method for conveying the material using the conveying system comprises: activating the vacuum pump device to create a pressure difference in the material conveyor pipe in order to convey the material through the material conveyor pipe and into the separator device; conveying the material from the separator device and into the transport container by a suction created by the vacuum pump device; and at least part of conveyor air on the pressure side of the vacuum pump device is conducted to an upper part of the separator device.
