High-efficiency and low-loss intelligent control is the development trend of non-metallic ore crushing technology and equipment
From June 4th to May 5th, during the China Non-Metallic Minerals Industry Conference held in Shanghai and the 9th National Non-Metallic Mineral Processing and Application Technology Exchange Conference, Professor Zheng Shuilin from Huahuan University and China University of Mining and Technology, along with Zu Zhanliang, Secretary-General of the China Non-Metallic Minerals Industry Association, presented key trends in the development of non-metallic mineral crushing technology and equipment. They highlighted the direction toward high efficiency, low energy consumption, and intelligent control systems.
According to reports shared by Zheng and Zu, more than 40 million tons of non-metallic minerals require processing annually across mainland China. These materials vary widely in hardness, ranging from low-hardness ores like talc and gypsum to high-hardness ones such as quartz and zircon. Due to their diverse applications, the required particle sizes differ significantly, spanning from 1mm down to 10 microns, with ultra-fine powders reaching into the hundreds of microns. As a result, existing mechanical crushing methods have led to the development of multiple crushing processes and equipment, aiming to reduce energy use and wear, ensure product quality stability, and develop efficient, cost-effective classification technologies. The integration of supporting technologies and artificial intelligence for control is expected to become a major focus of future innovation in the industry.
The event was jointly organized by the Non-Metallic Minerals Association and the Mineral Processing and Utilization Technology Committee. Over the years, this annual conference has evolved into a well-known platform for showcasing new technologies, products, and equipment in the mineral processing sector. It has also become a key channel for companies to promote their services, exchange information, and explore potential collaborations.
More than 170 participants attended the conference, discussing topics such as the “Eleventh Five-Year†development plan for non-metallic industries, current progress in non-metallic mineral crushing and processing technology, and the status of materials like wollastonite, talc, gypsum, coal-based kaolin, fluorite, and silicon raw materials. The event also covered application trends in the paper and plastic industries, advancements in ultra-fine grinding equipment both domestically and internationally, and research on functional non-metallic materials such as graphite, diatomite, sepiolite, and sericite. The discussions provided valuable insights into the evolving landscape of the non-metallic minerals sector.
