en.Wedoany.com Reported - China's Zhejiang Zhekuang Heavy Industries Co., Ltd. (300837) announced on June 26, 2026, that it has been granted a utility model patent, titled "A Modular Efficient Deployment Production Line for Sand and Gravel Aggregates," with patent application number CN202521343289.7. This technical solution constructs an efficient cyclic crushing system that can be rapidly deployed and flexibly adjust the process flow through the coordinated operation of a vibrating feeder, primary and secondary crushing units, screening units, and multiple conveying systems.

Founded in 2003 and headquartered in Changxing County, Huzhou City, Zhejiang Province, Zhekuang Heavy Industries Co., Ltd. is a leading domestic manufacturer of sand and gravel aggregate equipment, listed on the ChiNext board of the Shenzhen Stock Exchange in 2020. The production line adopts a modular design, with each unit operating independently yet closely interconnected. Oversized materials enter secondary crushing to form a closed-loop cycle, while undersized materials are separately output by multiple discharge conveyors, achieving precise grading control. This innovation shortens equipment installation cycles and significantly reduces on-site construction difficulty, making it particularly suitable for temporary or mobile operation scenarios such as mines and infrastructure projects.

Since the beginning of this year, Zhekuang Stock has accumulated a total of 22 patent grants. According to the company's 2025 annual report data, its R&D investment reached 21.0468 million yuan, a year-on-year increase of 0.81%. Tianyancha data shows that the company holds a total of 376 patents, 106 trademarks, and 5 copyrights, and has participated in 97 bidding projects and invested in 10 enterprises.

This patent grant further consolidates Zhekuang Stock's leading position in the field of sand and gravel aggregate equipment. With the continuous release of demand for infrastructure construction, modular production lines with efficient deployment capabilities are expected to see broader application.
