(Summary description)When designing a pneumatic conveying system, many factors are considered, many of which are hidden. Two pneumatic conveying manufacturers may use the same materials and even some of the same equipment, but each manufacturing process requires special adjustments based on different conditions. Even between two plants with the same equipment configuration, factors such as humidity can change the operating conditions of a pneumatic conveying system and may require minor adjustments to ensure better performance.   Knowing the material properties of pneumatic conveying and mastering the subtleties of pneumatic conveying can make a pneumatic conveying system operate normally 7*24 hours without special attention. This is the pursuit of factory managers, maintenance workers and design engineers when considering the installation of pneumatic conveying systems. The goal. Knowing how a pneumatic conveying system works is certainly helpful in purchasing, but the user responsible for purchasing a pneumatic conveying system does not have to be an expert in pneumatic conveying science. But what is more needed is a clear knowledge of the desired goal of the pneumatic conveying. Some users want to automate the production process more, others want to reduce labor intensity or create a cleaner work environment, and still others have the primary goal of increasing conveying capacity. In addition to clarifying the goals of the pneumatic conveying system, the user needs to know more information and tell the pneumatic conveying system manufacturer that this information will help the conveying system manufacturer to manufacture a custom or semi-custom system to provide the desired results.   The properties of pneumatically conveyed materials, such as bulk density, particle size and shape, and knowing whether the material is abrasive, brittle, dusty, cohesive, hygroscopic, etc., have a significant impact on system size and delivery method. In the vacuum pneumatic conveying system, the air conveys the powder material through the conveying pipeline. If there is too much gas, the powder content will be lower, and reducing the amount of air will allow more product to pass through the pipe. An everyday example of this is sipping a drink through a straw. If you put a straw in a cup, the straw will be filled with liquid when you suck, because there is very little air; however, if the end of the straw is placed on top of the liquid, the straw's function is mainly to suck the air out of the straw, and the sucked beverage will be very little.   In its simplest terms, a dilute phase pneumatic conveying system injects more air into the conveying line (such as a straw placed on top of the liquid), while dense phase pneumatic conveying injects less air and more product into the conveying line (e.g. The straw is inserted into the bottom of the cup). Most pneumatic conveying systems are used in dilute phase systems, while dense phase pneumatic conveying systems are more complex and have a smaller scope of application. In addition, in some cases, semi-dense phase pneumatic conveying systems may be employed, with dilute phase systems employing higher air flow velocities than dense phase systems. In addition, the pneumatic conveying system may be negative pressure pneumatic conveying or positive pressure pneumatic conveying. Negative pressure pneumatic conveying sucks the material away through the pipe, while positive pressure pneumatic conveying blows or pushes the material into the pipe. The choice between negative pressure pneumatic conveying and positive pressure pneumatic conveying depends on factors other than material properties, such as the conveying distance, and the size of the conveying rate.   In addition to knowing the vertical and horizontal conveying distances, the user also needs to inform the conveying system manufacturer of the number of feeding points, the type of container at the conveying point, whether the conveying process is continuous, the feeding speed, the number of discharging points, etc. If the material needs to be processed in the middle, Such as automatic weighing of ingredients, homogenization and stirring, etc., are more complicated.
