Powder vacuum feeders are dust-free, enclosed pipeline conveying devices that utilize vacuum suction to transport powdered materials. By leveraging the pressure difference between the vacuum and the ambient environment, they generate airflow within the pipeline to drive the movement of powdered materials, thereby achieving powder conveying.
In the past, many powder processing enterprises in China relied on traditional manual feeding methods. In this process, workers came into direct contact with materials three times, and the materials had to pass through three intermediate containers before reaching the next production step. This not only increased labor intensity and complicated the process but, more importantly, raised the risk of cross-contamination. Additionally, during transportation, significant amounts of dust could be generated, polluting the environment and affecting the health of operators.
An ideal conveying method should minimize direct contact between personnel and materials, enabling transportation within a sealed environment. This approach not only reduces labor requirements and costs but also prevents cross-contamination, enhancing the automation level of solid preparation production processes.
The powder vacuum feeder features a vibration-insensitive structural design combined with advanced control algorithms, allowing it to be directly installed at the feed inlet of the main machine. It employs loss-in-weight weighing technology to control the mixing and batching process, meeting high precision production requirements. With automatic calibration functionality, users can complete debugging in a very short time. The use of high-precision hybrid stepper motors ensures accurate metering and a wide output range. It also includes formula storage and retrieval capabilities, enabling quick machine startup.
