The LINGLING WFJ Black Beans Air Classifier Mill consists of three core components: the main grinding unit, auxiliary system, and electric control box.
The main machine completes the core grinding work, the auxiliary system provides essential support for continuous operation, and the electric control box precisely manages all working parameters.
This mill adopts air classification technology, eliminating the need for sieves or nets, ensuring evenly granulated black bean powder with stable quality and consistent results.
1. Rugged and stable structure, easy to install, operate and maintain with low labor cost.
2. Equipped with high-quality core components from world-famous brands, including motors, bearings and electrical parts, for long-term reliable performance.
3. Fully enclosed dust-free operation design, all dust is collected in the built-in dust collection box during production, ensuring a clean working environment.
4. Adjustable powder fineness via air classifier speed control, suitable for black beans, grains, cereals and other food materials grinding.
Material enters the Black Beans Air Classifier Mill through a screw conveyor. In it, fast-spinning blades cut and grind the beans. Once past the guide ring, they reach the classification chamber. Bigger particles get tossed back for more grinding, while smaller ones go straight to the cyclone separator and dust box.
