A processing device for conveying and mixing bulk material has a mixing and conveying station and at least one conveying pipe for supplying the bulk material to the mixing and conveying station. A vacuum-generating system with a vacuum hose or pipe is connected to the mixing and conveying station. An air supply is connected to the mixing and conveying station and introduces air for conveying and mixing the bulk material. A screen is arranged within said mixing and conveying station for separating the bulk material from the air. The screen has screen openings matched to a desired level of separation. The air from the air supply flows into the bulk material and effects mixing of the bulk material and removal of dust from the bulk material. The air has a temperature of 40 degrees C. to 200 degrees C.
