On November 11-12, the "2023 East China Sea Forum - The Third Seminar on Analysis of Sand and Gravel Production Process", which was hosted by Sand and Gravel Aggregate Network and co-sponsored by Weihai Haiwang Cyclone Company Limited, came to a successful end in Shaoxing, Zhejiang Province! As the industry's leading equipment research and development and manufacturing enterprises, Haiwang with green and efficient intelligent grading and sorting sand washing process technology appeared in the meeting, to discuss the future development path of the sand and gravel industry, low carbon and energy saving, building green mines, reducing energy consumption for the goal of production, and to contribute to the effort.

At the summit site, Sun Wei, director of Energy and Environment Research Institute of Haiwang, made a theme report of "Application of Neptune's High-efficiency Separation Technology in the Sand and Gravel Industry", and introduced a series of Haiwang's new technologies and equipment for sand washing, fine sand recovery, water treatment, etc., such as sand washing and fine sand recovery machine, high-precision countercurrent sand washer, and inclined-plate concentrator, etc., as well as their successful applications in dozens of large-scale sand and gravel production lines in China, providing a system solution for the large-scale, low energy consumption and high-efficiency sand washing system for users in the sand and gravel industry. Provide system solutions for large-scale, low-energy, high-efficiency sand washing system for sand and gravel industry users.

In the annual selection of the industry,Haiwang won the title of [Excellent Equipment Supplier] [Innovative Enterprise] in the sand and gravel industry in 2022, and Sun Wei, Director of Energy and Environment Research Institute of Haiwang won the title of [Process Technology Expert] in the sand and gravel industry in 2022.

This year's summit, with the theme of "firm confidence, release potential, sand out of the heavy siege, common stone hard", attracted a total of more than 700 industry guests, such as sand and gravel associations across the country, sand and gravel enterprises, cement companies, engineering units, equipment companies, experts and scholars from major universities and colleges, etc.

In the field of fine sand washing and recycling, Haiwang has been the leader in the industry after more than 30 years of development.
