Liming Heavy Industry joins hands with leading phosphorus chemical enterprises to build a model for high-value utilization integrating mining and battery materials

Phosphate rock is a non-renewable scarce resource and a vital economic mineral resource in China. It was included in China's Strategic Mineral Catalogue in 2016, serving as a core cornerstone for the development of multiple industries.

In recent years, driven by the advancement of agricultural modernization and the rapid growth of the new energy sector, demand for phosphate rock and its high value-added downstream products has kept rising across industries. The phosphate rock processing industry is undergoing large-scale expansion, while resource recycling sees growing vitality and market competitiveness.

Phosphate rock plays an essential role in key sectors including agriculture, new energy, chemical engineering and building materials. As the phosphorus chemical industry chain further expands into new energy fields, higher standards are set for the precision, efficiency and operational stability of phosphate rock processing. Equipment manufacturers are required to leverage solid technical expertise and customized solutions to deliver full-process technical support, paving a solid path for industrial upgrading.

Based in the heartland of abundant phosphate rock resources in Guizhou, Liming Heavy Industry, drawing on nearly four decades of expertise in milling equipment, has tailored exclusive solutions for a leading phosphorus chemical enterprise. We focus precisely on the phosphate rock pulverization process at the upstream end of the industrial chain, fueling the upgrading of the phosphorus chemical industry and coordinated development of the new energy sector.

Material Processed: Phosphate rock

Application: Lithium iron phosphate cathode material

Equipment: Liming Heavy Industry MTW European Trapezium Grinding Mill

Liming Heavy Industry MTW European Trapezium Grinding Mill stands out as the core equipment for raw material preparation in this project thanks to its high efficiency, reliable performance and large-scale production capacity. Its powerful grinding capacity, combined with fully optimized processes, produces powder with stable particle size and consistent quality for subsequent complex chemical reactions, ensuring efficient and stable operation of the entire industrial chain from the source.

Phosphate rock processing imposes stringent requirements on the efficiency, energy consumption and stability of grinding technology. The grinding process is a key factor determining resource recovery rate and product added value.

MTW European Trapezium Grinding Mill: Empowering High-quality Phosphate Rock Processing

To meet the stringent requirements for phosphate rock processing, Liming Heavy Industry MTW European Trapezium Grinding Mill, developed with in-depth understanding of phosphate rock properties, has become core equipment driving high-quality development of the phosphorus industry, setting an industry benchmark for efficient resource utilization in practical projects.

Boasting multiple core strengths, the mill adopts innovative grinding technologies and achieves breakthroughs in drive system, lubrication system, air duct design, roller and ring structure, finished particle size control, powder classifier system, air inlet volute and intelligent control system. It delivers high-efficiency, stable, energy-saving and intelligent powder production.

Raw materials are fed uniformly, quantitatively and continuously into the main grinding chamber via a variable-frequency belt feeder. The ground materials are conveyed by fan airflow to the classifier for classification. Under the operation of the analyzer, materials failing to meet fineness standards fall back into the chamber for re-grinding, while qualified powder is carried by airflow through pipelines into the cyclone collector for separation and collection, and discharged as finished products via the discharging unit. The separated airflow returns to the fan through the air return duct on the top of the cyclone collector. The whole production system operates under negative pressure and fully enclosed conditions. Equipped with a pulse dust collector, it prevents dust leakage and complies with national environmental protection standards.

Efficient utilization of phosphate rock resources serves as a dual pillar for safeguarding food security and advancing the new energy industry. The successful application of Liming Heavy Industry MTW European Trapezium Grinding Mill in the Guizhou phosphate rock project has verified its reliability under complex working conditions and established a replicable technical model for phosphate rock resource utilization. Centered on technological innovation, Liming Heavy Industry deeply caters to the demands of the phosphorus chemical and related industries. We deliver premium equipment and tailored solutions to join industry partners in pursuing efficient resource utilization, so as to maximize the value of every ounce of phosphate rock resources.
