Pneumatic Conveying System

3. We, as a company, Stratgem, are purposefully writing this informative blog to create awareness and share knowledge about pneumatic conveying systems with those who are very much interested in them. Everyone knows that a specific system is required for the transportation of dry bulk materials or powders. In this kind of process, dry bulk materials or powders are carried, transported, or shifted from one destination to another using compressed air or gases like nitrogen. The bulk materials, or granules, are transferred or shifted through tubes or an enclosed conveying pipeline by the collective force of pressure, and for that, compressed air or gas is used. Air movers such as positive displacement blowers or vacuums can generate the pressure and air flow, which are then used to convey the materials. That’s why, by controlling the pressure differential and air flow, the system can effectively convey or shift the materials over certain places or distances.

4. Air development devices such as fans, root blowers, or blowers perfectly create this air flow pressure. The pneumatic conveyor system is a cost-effective, or in other words, economical, system because it transfers or shifts powdered and granular materials successfully with very little loss, stops environmental pollution, and keeps the materials themselves clean and free of contaminants. Many process industries, including chemicals and detergents, pet food, food and beverage, renewable energy, and specialty materials, now rely on Stratgem's cost-effective pneumatic conveyor system. Whenever powder or bulk material is used in a plant, it should be transported or shifted in a systematic manner, as well as with the help of material handling equipment. These systems safely transfer or shift items or objects from one place to another, and they typically come in the form of conveyors and elevators.

5. Stratgem, based in Pune, India, creates pneumatic conveying systems that are much more reasonable and economical than other mechanical systems. Our pneumatic conveying systems are completely enclosed, reasonably controlled, and easily modifiable. Instead of mechanical systems, they are more environmentally friendly. Because of their enclosed design, they keep the materials conveyed safe and free of harmful foreign matter.

6. There are two types of pneumatic conveying systems. • Dilute phase conveying system • Dense phase conveying system Each type can convey materials using either a vacuum or a pressure method. These types can be distinguished by their operating principles, which refer to the type of material that can be moved and the source of airflow.

7. Dilute-phase pneumatic conveying Dilute-phase pneumatic conveying is described as the process of (pressure) pushing or (vacuum) pulling particles suspended in air from one location to another. At low pressure and high velocity, the air-suspended particles are transferred continuously. Mainly, there are two maintypes of Dilute-phase conveying systems: • dilute-phase pressure conveying • positive pressure systems

9. Dilute-phase pressure conveying In dilute-phase pressure conveying, a gas, such as air, is used to suspend and transport particulate materials through a pipeline. This method is the most commonly used for transporting dry materials because it is nonabrasive, resilient, and has a low bulk density over long distances. Such materials used in this method include plastic grains, sugar, and flour. Positive pressure systems In positive pressure systems, the gas is supplied to the inlet of the conveying pipeline at a pressure higher than the atmospheric pressure. This causes the mixture to flow through the pipeline under positive pressure.

10. How Positive Pressure SystemsWork • In this type of system, an air mover, commonly a positive displacement blower, is fixed at the start of the system to supply a high volume of low-pressure air. • A feeder and rotary airlock valve are placed next in the line after the blower, which helps to methodically "feed" the materials into the line. • As the materials enter the line, an air stream supplied by the blower quickly pushes and suspends the particles from one location to another. • The method is commonly used to convey materials from a single destination to multiple locations

11. Dilute Phase Vacuum Systems Vacuum systems: In vacuum systems, the gas is exhausted from the conveying pipeline, creating a vacuum that causes the mixture to flow through the pipeline under negative pressure. How Dilute Phase Vacuum SystemsWork • It operates in the exact opposite manner as pressure conveying. • To pull material from a storage hopper, a positive displacement vacuum provides negative pressure. • The vacuum pump is placed at the opposite end of the line to supply the suction needed to pull material from one location to the next. • A vacuum relief valve is used to control the negative pressure in the system and ensure that the right amount of material is delivered to its destination or multiple locations.

12. Dense phase conveying system Dense phase pneumatic conveying is the process of pushing (pressure) or pulling (vacuum) particles that are not suspended in the conveying air. The densely transported materials are transferred at high pressure and low speed (velocity). Dense phase conveying is classified into two types: • Dense-phase pressure conveying •  Dense-phase vacuum conveying

14. Dense-phase pressure conveying • The dense-phase pressure conveying method is commonly used to convey abrasive or fragile materials over great distances at extremely low speeds. • Beans, cocoa, hazelnuts, cereal, candies, and glass particles are examples of materials commonly transferred using this method. • This system is known for the benefit of starting or stopping with the conveying line full of material.

15. How dense-phase pressure conveying works • Material conveyed by this type of method is first loaded into a pressure vessel or blow pot. • Once the blow pot is filled, the material vent and inlet valve are closed, and compressed air is pushed into the vessel. • The compressed air pushes the material from the vessel and into the conveying line, where it reaches its destination. • "The process is restarted once all of the material in the vessel and conveying line has been transferred. It is common to install air injectors or jets along the length of the conveying line to help boost the material.

16. Dense-phase vacuum conveying • Dense-phase vacuum conveying systems are used for the transport of abrasive or fragile materials over short distances at low speeds. • Dense-phase vacuum conveying is commonly used to unload materials from rail cars and trucks in a fluidized state. • It has also been used for pharmaceutical and food applications. How it works: • These types of systems use vacuum pumps to convey material from a silo or hopper to a receiving vessel known as a vacuum hopper. • When the vacuum hopper is full, the material is then ejected to a destination silo. After all the material has been conveyed from the silo or hopper, the process can be repeated to transfer additional material as needed.
