China's First 50m³ Ilmenite Flotation Line Commences Operation｜Jasung Permanent Magnet Direct Drive Motor Passes Complex Application Validation
China's first dedicated 50m³ large-scale ilmenite flotation production line at Xichang Mine, Chonggang Mining, has recently been successfully commissioned. This marks a key milestone in the mine’s journey to become a leading enterprise in the development and utilization of vanadium‑titanium resources in China. The 50m³ dedicated ilmenite flotation cell adopted for this line is equipped with Jasung permanent magnet direct drive motors, which have undergone system‑level industrial validation under high‑density, high‑specific‑gravity ilmenite flotation conditions.
01 Project Background: Large Volume, Heavy Minerals, Challenging Conditions
Ilmenite flotation is characterized by high slurry density, heavy mineral specific gravity, and significant operational fluctuations, demanding greater performance in terms of equipment scale, reliability, and intelligent control. To address limitations of traditional equipment such as insufficient scale, low energy efficiency, and high maintenance costs, Chonggang Mining partnered with BGRIMM Machinery & Automation to launch the "R&D and Application of 50m³ Dedicated Ilmenite Flotation Cells" project. The project focused on integrated innovation of core equipment and key processes. For the flotation cell’s core components, a structural design featuring "centrally positioned impeller + lowered overflow weir height" was adopted, complemented by combined technologies such as "double‑side froth scraping + V‑shaped froth pushing" to meet the demands of high‑density, high‑specific‑gravity ilmenite flotation. This placed higher requirements on the drive system: high torque, low speed, stability, and controllability.
02 Permanent Magnet Direct Drive Motor Supports Stable Operation of 50m³ Dedicated Flotation Cell
As the core drive component of the 50m³ dedicated ilmenite flotation cell, the Jasung permanent magnet direct drive motor played a key role in the following aspects:
• High‑Torque, Low‑Speed Direct Drive: Eliminating intermediate speed‑reduction components, it delivers ample torque, adapting to the continuous operational demands of large‑volume flotation cells under conditions such as startup, stalling, and slurry fluctuations.
• Simplified Drive Chain: Reducing mechanical components such as shafts and couplings minimizes vibration sources and failure points, enhancing overall reliability.
• Improved Energy Efficiency and Control Precision: Integrated with intelligent frequency conversion and process control systems, it enables fine‑tuning of speed, torque, and process parameters, creating greater flexibility for process optimization.
• Adaptability to Harsh Conditions: With structural and protection designs tailored for wet slurry, heavy dust, and frequent start‑stop cycles, it ensures long‑term stable operation.
Driven by the permanent magnet direct drive system, the 50m³ dedicated flotation cell achieved the commissioning goal of "zero incidents, zero fault‑related stoppages" throughout single‑unit debugging, integrated test runs, and full‑load operation, laying a solid foundation for subsequent long‑term operation.
03 Enhanced by Intelligent Control, Process Indicators Reach New Heights
In parallel with equipment upgrades, the production line has also deployed a preliminary intelligent control system, integrating:
• Precise reagent addition control;
• Intelligent coupling adjustment of slurry level and aeration volume;
• Coordinated frequency control of key equipment.
Through fine‑tuning of parameters such as aeration volume, valve opening, reagent dosage, and frequencies for agitation, slurry pumps, and scrapers, the process has shifted from "experience‑dependent" to "data‑driven." This has reduced operational intensity by approximately 30%, significantly improved process stability and repeatability, and provided a replicable model for future flotation expert systems and exploration of "unmanned concentrators."
Field statistics show:
• Titanium concentrate output per unit time reached a record high;
• While ensuring stable production of high‑quality titanium concentrate, the TiO₂ content in flotation tailings was consistently maintained at around 3%, achieving the best historical level and significantly improving comprehensive resource utilization.
04 "Real-World" Validation Under Complex Conditions
For Jasung, this project not only represents the first large‑scale application of permanent magnet direct drive motors in dedicated 50m³ ilmenite flotation cells, but also serves as systematic validation under high‑density, high‑specific‑gravity, long‑duration continuous operation:
• It validated drive‑solution matching for large‑volume flotation cell conditions;
• It passed the full‑process test from commissioning and integrated trials to full‑load operation;
• It accumulated integrated experience and a data foundation for subsequent promotion and application in similar complex mineral processing contexts such as ilmenite and vanadium‑titanium magnetite.
05 Looking Ahead: From Single Equipment to Full‑Process Drive Solutions
The successful commissioning of the nation’s first dedicated 50m³ ilmenite flotation production line provides a new technological pathway for efficient flotation of high‑specific‑gravity minerals and sets a new benchmark for deep integration of large‑scale, high‑efficiency flotation equipment with advanced processes. Building on this project, Jasung will continue to focus on mineral processing scenarios such as titanium, vanadium‑titanium, and iron ores. Centered on permanent magnet direct drive motors, intelligent control, and full‑process drive solutions, Jasung will collaborate with industry partners to advance continuous upgrading in energy savings, quality improvement, intelligentization, and localization of equipment in the mineral processing sector.
