Recently, Shanghai Rucca received an invention patent certificate issued by the China National Intellectual Property Administration - * * "a dual centrifugal separation structure sand mill" * * (patent number: ZL 2024 1 0433040.9), and the authorized announcement date is September 4, 2026.
This is another breakthrough by Rucca in the core technology of sand mills.
What problem does this patent solve?
The discharge separation system of the sand mill directly determines whether the grinding medium can be effectively intercepted and whether the slurry can flow out smoothly. The traditional single-stage separation structure is prone to two problems under ultrafine grinding medium conditions: first, incomplete separation, and fine beads may be carried out with the slurry; Secondly, the discharge efficiency is limited, which affects the overall production capacity of the line.
The 'dual centrifugal separation structure' is specifically designed for this stage. Through the coordinated design of two-stage centrifugal separation, the smoothness of discharge and separation efficiency are improved while ensuring that the grinding medium does not leak, especially suitable for continuous production under ultrafine grinding medium conditions.
The application scenario of this technology directly points to the direction that Rujia has been focusing on in recent years - nanoscale grinding. Whether it is new energy battery materials, MLCC ceramic slurries, solid electrolytes, or carbon nanotube conductive slurries, higher requirements have been put forward for the discharge separation system. If the separation structure is not up to standard, ultrafine beads cannot be used, and nanoscale grinding cannot be discussed.
Behind patents lies continuous investment in research and development
Rucca has been established for over ten years, focusing on the field of wet dispersion grinding. As of now, the company has accumulated multiple invention patents, utility model patents, and software copyrights. Its products have passed CE and ISO9001 certifications and have been recognized as national high-tech enterprises.
The authorization of this invention patent is a milestone achievement of Rucca in the independent research and development of core components. From the pin type high-energy density structure, to the dual cooling system inside and outside, to the current dual centrifugal separation structure, each technology has been repeatedly validated based on actual production line requirements, and finally returned to the production line for inspection.
Technology serves products, products serve customers
For Rucca, patents are not meant to be hung on walls. The value of a technology ultimately depends on whether it can run steadily, produce well, and be used for a long time on the customer's production line.
Thank you to every customer and partner. Rucca will continue to focus on its main business of grinding, deepen its technology, improve its equipment, and provide solid services.
