November 16-17, 2026, Gucheng, Xiangyang, Hubei.

On the day of the celebration of Yifu Intelligent Hubei New Industrial Park, the forum’s attention focused on the section of the lithium iron phosphate production line that is most likely to be “illustrated”—feeding and grinding. When the industry returns from "formula involution" to "process control determines life and death", the real cost and consistency of LFP are often not produced by firing, but by grinding: the premix is ​​not evenly mixed, the sanding particle size collapses, and the batch CV drifts. No matter how accurate the subsequent kiln is, it cannot be saved.

In this round of "returning to basic manufacturing skills", we invited an old engineer who has moved the iron-lithium production line from drawings to mass production——Liu Hanyun, general manager of Dongguan Xingchen Lithium Energy Consulting Co., Ltd. He is a distinguished expert on phosphates from the China Chemical Society, a member of the SMM and Today's Lithium Battery New Energy Materials Expert Committee. He once served in the executive team of Hubei Wanrun New Energy and led the implementation of multiple iron phosphate and lithium iron phosphate projects. He is also one of the authors of the monograph "Solid Phase Method Lithium Iron Phosphate Industrial Production Technology and Equipment". He is officially confirmed to attend this forum and the housewarming celebration of Yifu Smart Hubei New Industrial Park, and will bring a theme report "Lithium Iron Phosphate Feeding and Grinding Process, Process Mechanism and Equipment Selection". From bag removal and iron removal to sanding and discharging materials, he will explain "how to stabilize the front section" in one go.

A practical school that nails the “whole process of iron-lithium production line” into process details

Mr. Liu Hanyun is the general manager of Dongguan Xingchen Lithium Energy Consulting Co., Ltd. and an expert in the industrialization of lithium battery cathode materials. He once served as a senior executive of Hubei Wanrun New Energy and a specially appointed expert of Sichuan Falongmang.Leading the implementation of multiple 10,000-ton iron phosphate and lithium iron phosphate projects from planning to mass production. He is currently a distinguished expert of the Phosphate Professional Committee of the Chinese Chemical Society and an expert of the SMM New Energy Materials Expert Committee. Co-authored with"Solid Phase Process Lithium Iron Phosphate Industrial Production Technology and Equipment"He has written a book, and has given speeches at domestic and foreign industry conferences on topics such as large-scale iron-lithium production lines, foreign matter prevention and control, and process control. Xingchen Lithium Energy, founded by him, focuses on providing full-chain consulting services such as production line planning, equipment selection, personnel training, and production compliance for new lithium battery materials companies.

In his early years, he worked as a senior executive at Wanrun New Energy, the leader in lithium iron phosphate, and oversaw project construction, process debugging and production capacity ramping. Later, with Xingchen Lithium as the main body, he focused on providing full-process consultation of "production line planning - equipment layout - selection - installation and commissioning - personnel training - standardization" for new lithium battery materials companies. When it comes to large-scale iron-lithium equipment and iteration of solid-phase manufacturing systems in the industry, his judgment is often used as a benchmark: before 2020, it will be a small-scale intermittent type, and after 2020, it will be a new industrial paradigm with a single line of 30,000-50,000 tons, a hundred-square-meter reactor, and automation of sand grinding and iron removal.

Mr. Liu Hanyun has written books, been a salon speaker, and worked on the production line to put out fires. For the feeding section, he looks at dust, bridging, iron removal and formula error prevention; for the grinding section, he looks at D50 target, span distribution, temperature rise, media abrasion and batch recurrence. This overall experience of "from the feeding port to the spray drying tank" allows him to always put the process mechanism in front of the parameter table when selecting equipment.

In-depth echo with the theme of the forum "New Energy and New Materials"

Mr. Liu Hanyun’s report "Lithium Iron Phosphate Feeding and Grinding Process, Process Mechanism and Equipment Selection", just in time to bring this forum's "new materials drive new batteries" back to the hardest front-end manufacturing site:

Feeding and premixed layer - LFP dry powder feeding must first go through pipelines to remove iron, weightless ingredients and vacuum wetting. Pre-dispersion determines the sanding efficiency: the soft agglomerates that have not been broken up will only become coarser when entering the sand mill. The solid content, viscosity, and dispersant type must match the subsequent grinding bead diameter, otherwise secondary agglomeration and coarsening after standing will occur.

Grinding mechanism layer - Wet sanding relies on the synergy of three forces: shearing, collision and friction: coarse grinding to break agglomeration, fine grinding to control D50, and ultra-fine segment pressure Span. LFP is not as fine as possible. The finished positive electrode D50 usually matches the 3.5-5μm range. Too fine will sacrifice compaction, increase specific surface and energy consumption; the goal should be "narrow distribution + low magnetic foreign matter + reproducibility".

Equipment selection layer - 400L rod pin machine is suitable for 10,000-30,000 tons of flexible lines, 1000L direct drive machine is suitable for 50,000 tons + large-scale; the medium selection is cerium-stabilized zirconia 0.3-0.8mm, filling rate 70-85%, double-wall cooling temperature control <45℃, dynamic separation anti-blocking net. The selection is not based on "how many nanometers can be ground", but rather "can it be the same on your slurry batch after batch?"

For the material factory, it answered "Why is the fineness twice as fine if the same formula is used in different factories?"; for the equipment factory, it reminded that the separation system, temperature control, and ceramic contacts must be designed in advance; for Yifu, it meant that the new park production line must make feeding-premixing-sanding-demagnetization into a closed-loop data link. The moat of iron lithium is hidden in the set of particle size curves in the grinding chamber.

In the golden autumn of November, Gucheng’s new garden opens

Gucheng New Park opens. Yifu Intelligent has launched a new generation of rod pin sanding, high solid content dispersion and online particle size quality control production lines in Central China. On the surface, it is expanding production, but on the inside, it is building a model for "standardization of iron-lithium front-end processes". When Liu Hanyun talked about "process control to widen the gap" on the stage, every set of feeding rhythms of the front-end equipment, every temperature rise curve, and the amount of zirconium beads added in each batch will be directly written into the background of the pole piece coating and cell cycle.

From November 16th to 17th, the new park and forum opened simultaneously in Gucheng, Xiangyang, Hubei. It is recommended that all friends who are engaged in LFP, iron phosphate precursors, high-pressure compacted iron lithium and new production lines reserve a seat: listen to Mr. Liu Hanyun’s two-way experience from Wanrun production line to Xingchen Consulting, and explain clearly "the process of feeding and grinding, how to use mechanism to select equipment, and use data to manage batches"; also see how Yifu's new production line uses a continuous and auditable grinding system to catch the process rhythm of 10,000-ton mass production of iron lithium. The move is not a ribbon-cutting, but a re-sharpening of the basic skills of China's cathode manufacturing industry by billionaires and a generation of iron-lithium craftsmen in Gucheng.

Billion starts a new journey, a rich future, Gucheng New Park will see you there!
