Rotary feeders, also known as rotary valves or air locks, are the core supporting equipment of bulk material conveying systems for powders, particles, and other materials. They have dual functions of quantitative feeding and airtight isolation, and are widely used in industries such as chemical, food, pharmaceutical, building materials, and environmental protection. They are key devices for achieving continuous and stable material transportation in pneumatic conveying, dust removal, and ash discharge processes.

The core of the equipment consists of a rotor, a sealed shell, a driving device, and a sealing structure. It relies on the rotation of the rotor to form an independent chamber, which completes the transportation of materials from the feed port to the discharge port. At the same time, precise sealing design isolates the upstream and downstream pressure difference to prevent gas backflow and material leakage. Paired with a pressure equalization exhaust port, it can effectively avoid gas topping and ensure smooth transportation. The drive end supports speed adjustment, which can accurately control the material conveying volume and meet the quantitative feeding requirements of different processes.

This device has multiple performance advantages, and its closed structure can effectively prevent dust from escaping, which meets the requirements of environmentally friendly production; The key components are made of wear-resistant materials, suitable for various materials such as powder and granular, and can even handle abrasive and viscous materials, adapting to complex working conditions such as positive and negative pressure. The overall structure is compact and small, with a small footprint and flexible installation. The modular design makes daily maintenance and replacement of vulnerable parts more convenient, significantly reducing equipment operation and maintenance costs.

At the same time, the equipment supports customized design, and can be equipped with explosion-proof motors, high-temperature resistant bearings, special sealing methods, and other configurations according to industry needs. The shell and rotor materials can also be customized to meet the personalized needs of different production environments. With the characteristics of stable operation, low noise and energy saving, and strong adaptability, it has become an important equipment in modern material conveying systems to improve production efficiency and ensure process stability.
