Negative Pressure Conveying

Negative Pressure Conveying is one of airflow conveying. It takes use of the airflow energy to deliver the granules along the airflow direction inside the closed pipe， which is a specific application of fluidization technology. The Negative Pressure Conveying normally takes Roots vacuum pump as power source to vacuumize the material tank into some vacuum state. Under the atmospheric pressure, two phases flow of material and gas forms at the air inlet, and they enter the cyclonic separator through the pipeline; the two phases flow inside the cyclonic separator under the action of centrifugal force and gravity, most materials are separated from the gas, then enter into the materials tank, a small amount of material go into the dust collector along with gas. Through the filtration bag, the powder is separated from the gas and recycled. And the gas will be discharged to the atmosphere.
