The research and development project of China's highly efficient energy-saving grinding equipment passed the acceptance

Recently, the Department of Social Development Science and Technology of the Ministry of Science and Technology organized an expert on the “Eleventh Five-Year” National Science and Technology Support Program “Development of Highly Efficient and Energy-saving Grinding Equipment” and “Development of Large Heavy-duty High-pressure Thickeners” for the Changsha Research Institute of Mining and Metallurgy. "The two topics were checked and accepted. The expert group unanimously agreed to pass the acceptance of the two topics by listening to the reports, reviewing the materials and inquiries and discussions.

Development of "Large Heavy-Duty High-Pressure Thickeners" has developed a multi-head drive (independent research and development), a fluidized flocculant dilution technique and equipment, a non-ray measuring slurry concentration technique, and a novel concentration detection device non-radiation concentration meter, etc. Breakthrough the micro-grain material concentration and dehydration technology, tailings dry drainage and full tail filling technology; obtained a number of scientific and technological awards. The HRC-Z-25 heavy-duty high-pressure concentrator and its supporting systems independently developed by the project fill the gaps in the domestic industry, and have broad application prospects in the fields of mining, metallurgy, and environmental protection, and can produce good social, economic, and environmental benefits. “The research and development of high-efficiency and energy-saving grinding equipment” has developed the V6 industrial super-speed grinding machine, metal mine dedicated micro-grinding equipment - vertical spiral stirring mill, HHZ-type cyclone, large double-slot high-strength ultra-fine A batch of high-efficiency energy-saving grinding grade equipment, such as agitating ball mills, is used to develop magnetic linings that are well applied in a range of mills. 7 domestic invention patents were disclosed, of which 3 were granted patents, 14 academic papers were published, and 1 provincial-level scientific and technological award was obtained. The implementation of this project is of great importance to the development of fine-grained inlay minerals, deep processing of ultra-fine powders, etc., and provides strong technical support for energy saving, consumption reduction and reduction of ore processing costs in the field of mineral processing.
