Nano Rice Flour Pulverizing With Vibration and Suction Collection

The patent employs a vibrating screen with excitation mechanisms to generate mechanical vibrations that facilitate powder separation and collection. The vibration causes powder particles to bounce and separate from the processing stream, enabling efficient collection while minimizing material loss through controlled vibrational motion rather than simple gravitational settling

The patent utilizes pneumatic conveyance systems with controlled airflow to transport pulverized material through the device. By using regulated air currents, the system can precisely control material flow paths, directing powder to collection points while preventing unwanted dispersion and minimizing material loss during the conveyance process

The patent divides the pulverization process into multiple stages with different rotational speeds and grinding mechanisms. Instead of using one high-speed rotor, the system employs sequential grinding chambers or multi-stage classifiers that progressively reduce particle size at controlled speeds, achieving efficient pulverization while preventing excessive material damage and loss that would occur in a single high-speed stage

The patent implements variable speed control mechanisms that dynamically adjust rotational speeds based on material properties and processing requirements. The system can optimize rotation speed for each specific material type and processing stage, maintaining high pulverization efficiency while avoiding the material damage and loss associated with fixed high-speed operation
