40 Years of Gathering Granules, Intelligent Measurement Leading the Way | Micro-Nano Particle Instruments Invited to the 14th China Particle Conference, Celebrating the 40th Anniversary of the Chinese Society of Particulates

The 14th China Particle Conference (CCPT14) was recently held in Guangzhou. Coinciding with the 40th anniversary of the Chinese Society of Particulates, the event brought together experts and scholars, research institutes, and powder testing instrument enterprises from across China's particle field, with academic exchange, achievement showcase, and industry-academia-research collaboration as its core themes. Together, participants discussed the development of particle science and explored innovation pathways for powder testing technologies. Jinan Winner Particle Instrument Co., Ltd. exhibited its Winner311PRO Spray Particle Size Analyzer as a highlight of the event, and company leadership was invited to deliver a keynote report at a sub-forum, sharing innovative application results of online particle size monitoring technology in jet milling processes.

At the exhibition, Jinan Winner Particle Instrument Co., Ltd. showcased its latest-generation Winner311PRO Spray Particle Size Analyzer. Purpose-built for small-scale spray droplet size testing, the instrument features an intelligent, modular design with a dedicated motorized testing platform compatible with a wide range of nebulizers. Its high-speed acquisition system ensures rapid data collection and analysis, and the software includes built-in GMP-related functions. The system enables non-contact, precise measurement of airborne droplets, liquid droplets, aerosols, and powder mists, meeting pharmacopoeia testing requirements for inhaled aerosols, sprays, and powder mists in the pharmaceutical field. It is also widely used in nebulization R&D and spray process optimization, providing a reliable domestic testing solution for the development and quality control of spray products. The instrument drew considerable attention from experts and industry peers, who stopped by to inquire and exchange ideas.

During the academic report session at the sub-forum, company leadership delivered a presentation titled "Application of Online Particle Size Analyzers in Jet Milling." Addressing industry pain points—such as the lag inherent in traditional offline sampling, the inability to provide real-time feedback on powder particle size, and the reliance on empirical tuning of process parameters—the report systematically explained how an online particle size monitoring system can be integrated into jet milling production lines. The system enables continuous, real-time online monitoring of powder particle size, rapidly capturing key particle size data such as D50 and D97 to support dynamic optimization of process parameters including jet pressure, feed rate, and classifier wheel speed. This creates a closed-loop quality control process of "measurement–feedback–adjustment," improving batch-to-batch consistency of finished powder products and reducing rework losses. The approach supports intelligent manufacturing and quality controllability in powder industries such as lithium battery materials, pharmaceutical APIs, and fine chemicals. Drawing on numerous practical application cases, the report demonstrated the on-the-ground value of domestic online particle size testing equipment in dry grinding processes, earning positive recognition and lively discussion from attending experts.

As one of China's earliest high-tech enterprises dedicated to particle testing technology R&D, Winner Particle Instruments has consistently upheld its mission of "developing and popularizing advanced contemporary particle testing technology." The company continues to deepen its expertise across laser particle size analysis, online monitoring, spray particle size measurement, and image-based particle shape analysis, steadily refining domestic particle testing instruments that combine stability with practicality. It provides comprehensive particle size testing solutions for industries including university research, pharmaceuticals, new energy, advanced materials, and fine powders.

This participation in the conference was both a tribute to the 40th anniversary of the Chinese Society of Particulates and an opportunity for in-depth industry-academia-research exchange. Looking ahead, Jinan Winner Particle Instrument Co., Ltd. will continue to focus on innovation in particle testing technology, iterating its online particle size monitoring and spray particle size measurement product lines, tackling the challenges of industrial on-site measurement, and empowering the high-quality development of the powder industry with accurate and reliable domestic testing equipment. Together with industry peers, the company is committed to advancing China's particle science and powder manufacturing technologies to new heights.
