Pneumatic conveying systems are methods used to transport bulk materials through pipelines using air or gas. These systems can move a variety of materials, including powders, granules, and pellets, making them useful in industries like food processing, pharmaceuticals, and manufacturing. The process involves creating a pressure difference that pushes the material through the pipeline. There are two main types of pneumatic conveying: dilute phase and dense phase. In dilute phase conveying, materials are suspended in the air and moved at high speeds, while dense phase conveying transports materials at lower speeds with a higher concentration. Both methods offer efficient and flexible solutions for material handling.
