As the global new energy and chemical catalysis industries evolve, scaling the production of high-performance materials remains contingent upon the reliability of core equipment. With over 35 years of specialization in drying and calcination processing, Changzhou Fanqun Drying Equipment Co., Ltd. has emerged as a pivotal technology partner for leading material producers worldwide. 

Introduction: The Process Backbone of Advanced Material Manufacturing

While much attention is paid to material formulation, the performance of advanced materials—spanning next-generation battery chemistries and catalytic supports—is ultimately dictated by unit operations on the production floor. Specifically, within the drying and calcination units, the transformation of precursors into high-performance LFP, the purification of battery-grade Lithium Carbonate, or the precise thermal treatment of catalytic materials, all require extreme precision in temperature control, atmosphere management, and residence time.

Changzhou Fanqun addresses these challenges not merely as an OEM, but as a comprehensive process solutions provider. Since its founding in 1991, the company has focused on the unit operations that define product quality: drying, calcining, mixing, and conveying. With annual sales exceeding RMB 600 million, Fanqun operates as a National High-Tech Enterprise, integrating R&D, design, and manufacturing under one roof to serve the most demanding segments of the global chemical and new energy industries.

Core Technological Competencies

Fanqun’s competitive advantage stems from its ability to engineer stability and efficiency into high-temperature processes. 

Rotary Kiln Calciners: Precision at Scale

Fanqun rotary kilns are engineered for processes where atmosphere and thermal profiles are critical: activation, crystallization, oxidation, and reduction. Unlike standard kilns, Fanqun systems feature advanced sealing mechanisms and optimized refractory linings to ensure minimal heat loss and consistent product quality. These systems are the heart of production lines for:

* Lithium Carbonate purification and calcination.

* NCM/NCA and LFP cathode material synthesis.

* Graphite anode processing.

* High-temperature treatment of catalysts and environmental wastes. 

Spin Flash & Centrifugal Spray Dryers

To handle the diverse feedstocks of the battery industry, Fanqun offers specialized drying technologies:

* Spin Flash Dryers: Ideal for continuous dehydration of filter cakes and pastes (e.g., LFP precursors). The aggressive dispersion mechanism prevents material buildup, ensuring uniform moisture removal without thermal degradation.

* Centrifugal Spray Dryers: Converting solutions or slurries into spherical, free-flowing powders in a single step, crucial for controlling bulk density and particle morphology in precursor production.

Belt Calcine

Products are loaded onto the feed section of a continuous conveyor belt and advance through multiple processing zones. Each zone features independent hot air circulation and precise temperature control. The system automatically guides products through heating, stabilization, and cooling phases before discharging them at the outlet, completing the drying, calcining, and heat treatment cycle. One can easily adjust the material's residence time by varying the belt speed.

* Drying and calcining of preformed catalyst;

* Drying and calcining of automobile catalyst;

* Drying and calcining of De Nitration Catalysts;

* Annealing of workpiece;

* Thermal treatment of workpiece.

Landmark Production Capacities

Fanqun’s engineering prowess is best demonstrated through its large-scale turnkey projects. The following capacities represent the company’s benchmark achievements in high-tonnage battery material processing:

* 30,000–50,000 t/a Iron Phosphate Flash Drying & Rotary Kiln Production Line: As the first Chinese supplier of 10,000-ton-scale FePO₄ continuous drying and calcination systems, Fanqun leverages mature R&D and multi-stage waste heat recovery to deliver single-train 30,000–50,000 t/a turnkey lines that cut energy costs while upgrading industry competitiveness.

* 30,000–60,000 t/a Lithium Iron Phosphate (LFP) Rotary Kiln Production Line: Leveraging deep technical expertise in Lithium Iron Phosphate (LFP), the company pioneered replacing traditional roller hearth kilns with rotary kilns—optimizing sealing structures to overcome core challenges in coke discharge, oxygen control, and precision calcination—and has successfully commissioned single-train 30,000–60,000 t/a first-fire and second-fire lines, significantly lowering OPEX and establishing a new benchmark for high-end manufacturing.

* 16,000 t/a Lithium Carbonate Rotary Kiln Production Line: Engineered for converting spodumene or brine intermediates into battery-grade Li₂CO₃ (>99.5% purity). These lines are designed for low energy consumption per ton and continuous, stable operation.

Up to now, the annual production capacity supported by Fanqun’s equipment includes: 1,000,000 tons of ternary precursor materials, 3,300,000 tons of iron phosphate materials and 800,000 tons of lithium iron phosphate. With strong technical strength, it continues to empower the high-quality development of the new energy & chemical industry.

Strategic Advantages & Market Position

What distinguishes Fanqun in the global market is its system integration capability. Rather than supplying isolated machines, Fanqun delivers complete production lines—from raw material feeding and drying processing to gas treatment and intelligent control systems. This mitigates integration risks for clients and accelerates project commissioning.

The company’s R&D investment focuses on solving practical industrial problems: optimizing specific energy consumption (kWh/t), extending equipment service life in corrosive atmospheres, and providing digital monitoring solutions for predictive maintenance. This technical rigor has earned Fanqun a reputation as a reliable partner for both greenfield projects and capacity expansion initiatives.

Relying on profound technical accumulation and continuously upgraded intelligent precision manufacturing capabilities, while adhering to high-quality standards, Fanqun has reduced equipment energy consumption by 10 –15 per cent compared with the industry average. With the core advantages of energy saving, high efficiency and stability, its products are widely used in petrochemical, new energy, catalyst, pharmaceutical and other fields, winning high trust from customers worldwide.

Global Partnership Ecosystem

Fanqun’s equipment is specified by a global portfolio of Fortune Global 500 firms and industry leaders across the chemical, mining, and battery sectors. The company’s long-term strategic cooperation with these entities underscores its role as a qualified supplier of mission-critical process equipment.
