Qingdao Conqinphi Environmental Technology Group Co., Ltd. is a professional manufacturer specializing in advanced evaporation and crystallization solutions. Our Evaporative Crystallization of Lithium Salts for Battery Grade Lithium Hydroxide – 3MTPA Capacity system is designed to deliver high-purity lithium hydroxide monohydrate (LiOH·H₂O) essential for the growing electric vehicle and energy storage markets. With over 8 years of industry experience, a 10,000-30,000 m² factory, and ISO-certified quality management, we provide reliable, energy-efficient, and scalable equipment for lithium refining.
This system integrates forced circulation evaporation and controlled crystallization to convert lithium chloride or sulfate solutions into battery-grade lithium hydroxide crystals. It achieves consistent product purity exceeding 99.5% with minimal impurities. The 3MTPA (3,000 tons per annum) capacity is ideal for mid-scale production lines, offering a balance between capital investment and output.

Product Features & Benefits
- High Purity & Consistency: Advanced crystallization control ensures uniform crystal morphology and consistent battery-grade quality, meeting strict industry standards for LioH·H₂O.
- Energy-Efficient Design: Multi-effect evaporation and heat recovery reduce steam consumption by up to 30% compared to traditional single-effect systems.
- Corrosion-Resistant Materials: Wetted parts are made of 316L stainless steel or Hastelloy, compatible with corrosive lithium salt solutions and high-temperature operation.
- Modular Scalability: The system is designed for easy expansion; multiple units can be combined to achieve larger capacities (e.g., 6MTPA, 10MTPA).
- Automated Operation: PLC-based control with touchscreen interface minimizes manual intervention, reduces labor costs, and ensures repeatable quality.
- Low Maintenance: Anti-scaling and anti-fouling features prolong runtime between cleaning cycles, with easy access to key components.
- Compliance with Environmental Standards: Closed-loop design minimizes waste discharge; condensate water can be recycled, supporting green production.

Frequently Asked Questions (FAQ)
-
Q: What is the typical purity level of lithium hydroxide produced by this system?
A: The system is designed to produce battery-grade lithium hydroxide monohydrate with purity ≥99.5%, meeting the specifications required by cathode material manufacturers. -
Q: Can this system handle different feedstocks like lithium sulfate or lithium chloride?
A: Yes, the evaporative crystallization process is adaptable to both lithium chloride and lithium sulfate solutions, with minor adjustments to operating parameters. Customization is available upon request. -
Q: What is the typical footprint and utility requirements for a 3MTPA unit?
A: The system occupies approximately 200–300 m² (depending on configuration). Utility requirements include steam (approx. 2–3 tons/h), cooling water circulation, and electricity (about 150–250 kW). We provide detailed engineering data during design. -
Q: How does the system control crystal size distribution?
A: Crystal size is controlled by adjusting residence time, supersaturation ratio, and agitation speed. Our PLC program can automatically maintain target size distribution (100–500 μm) for optimal downstream processing. -
Q: Is after-sales technical support available?
A: Yes, we offer comprehensive after-sales services including remote troubleshooting, on-site commissioning, spare parts supply, and process optimization consultation. Our team is available 24/7 for urgent inquiries. -
Q: What certifications does the equipment have?
A: While the equipment itself is engineered to meet international standards, our factory operates under ISO9001, ISO14000, OHSAS18001, and other management systems. Custom certifications (e.g., CE, ASME) can be arranged based on your market requirements. -
Q: Can the capacity be expanded in the future?
A: Absolutely. The modular design allows you to add additional evaporator-crystallizer trains to increase total capacity. We can also retrofit existing lines for higher throughput. -
Q: What is the typical delivery time for a 3MTPA system?
A: Delivery time is typically 4–6 months after order confirmation, depending on customization complexity. We ship from Qingdao port, China, with full logistics support.
