1985  Prof. Zhongjing Ren directed a research project: the development of on-line cement particle analyzers, and that year this project was put into the list of the Seventh China’s Seventh Five-year-research-plan.
1990  The on-line cement particle analyzers passed the acceptance exam of China’s Seventh Five-year-research-plan The comments were ‘the pioneer of the art in China’ and ‘one of the most advanced technologies of this age’.
1993  The on-line cement particle analyzer won the gold medal at the First China’s Technology Expo.
1994  Took on a project of the Shandong province’s Eighth Five-year-research-plan which led to JL 9200 portable laser particle size analyzer, and had it patented.
1995  JL 9200 portable laser particle size analyzer was put into the list of ‘China’s most important new product’.
1996  Took on China’s Ninth Five-year-research-plan which led to JL 9300 laser dry-particle size analyzer. This invention won the third-grade ‘Award for Science & Tech. Progression in Shandong Province’.
2000  Jinan Winner Particle Technology Co. Ltd formally established.
2002  Winner laser particle size analyzer, Winner 2000, was approved by China’s Standard Material Research Center.
