Product Overview
The Lithium Battery Dry Mixing Homogenizer Integrated Machine is a professional-grade, all-in-one equipment tailor-made for the dry mixing process of lithium-ion battery materials, including cathode materials (e.g., lithium cobalt oxide, lithium iron phosphate), anode materials (e.g., artificial graphite, natural graphite), and auxiliary additives (e.g., conductive carbon black, binders). It integrates high-speed dispersion and precision stirring technologies to address the core demands of lithium battery dry mixing—such as ultra-high mixing uniformity, zero material contamination, and stable batch consistency. This machine ensures that dry powder materials achieve consistent particle distribution and tight component ratio control, laying a solid foundation for the subsequent electrode sheet pressing and battery cell performance (e.g., energy density, cycle life) of lithium-ion batteries. It is an indispensable core equipment for large-scale, high-quality lithium battery production lines.

Core Features for Lithium Battery Dry Mixing
Ultra-High Mixing Uniformity, Critical for Battery Performance
The high-speed dispersion disc (fixed 45 m/s linear speed) generates strong shear force to break up agglomerates of dry powder materials (e.g., graphite, lithium iron phosphate) that are prone to clumping, while the low-speed agitation disc (13 m/s linear speed) enables 360° circumferential mixing of the entire material batch. This dual-action design ensures the mixing uniformity of key components (e.g., conductive agent content) reaches ≤±0.5%, far exceeding the industry’s general requirement of ±1%, effectively avoiding local over-concentration or deficiency of materials that could cause battery internal resistance increase or cycle life decay.
Zero Contamination Design, Meeting Lithium Battery Purity Standards
All parts in contact with materials are made of 316L stainless steel (or optional Hastelloy for high-corrosion materials), with a surface roughness of Ra ≤ 0.8 μm to prevent material adhesion and residual. The machine adopts a fully enclosed mixing chamber (with optional inert gas protection function) to isolate air, moisture, and external impurities—critical for avoiding lithium battery material oxidation and moisture absorption (moisture content control ≤ 50 ppm after mixing). Additionally, the seamless welding process of the tank body eliminates dead corners, ensuring no material accumulation and easy cleaning (compliant with lithium battery industry cleaning validation requirements).
Stable Batch Consistency, Suitable for Mass Production
Equipped with high-precision frequency converters for dispersion and agitation motors, the speed control accuracy reaches ±1 rpm, ensuring consistent mixing intensity across different batches. The heavy-duty structural design (with a machine weight ranging from 500 kg to 9000 kg) minimizes vibration during high-speed operation, avoiding material stratification caused by equipment shaking. Combined with the flexible loading range (minimum 4 L to maximum 1859 L), the machine can maintain stable mixing effects whether in small-batch formula verification or large-scale 1859 L batch production.
High Efficiency & Energy Saving, Adapting to Industrial Rhythm
The matched dispersion and agitation power (ranging from 4 KW + 2.2 KW to 360-400 KW + 250 KW) is optimized for lithium battery dry materials—high enough to break up hard agglomerates, yet not excessive to cause unnecessary energy consumption or material overheating (temperature rise during mixing ≤ 10℃, protecting heat-sensitive additives). Compared with traditional double-cone mixers, the mixing time is shortened by 30%-50%, significantly improving the production efficiency of lithium battery electrode material lines.
Safety & Compliance, Aligning with Industry Norms
The machine is equipped with multiple safety interlocks: emergency stop buttons, overcurrent/overload protection for motors, and pressure relief valves for the mixing chamber (to prevent dust explosion risks in dry powder mixing). It fully complies with international standards such as IEC 61508 (functional safety) and GB/T 30835 (lithium battery production equipment safety requirements). The detachable dispersion/agitation discs and modular design also facilitate maintenance and replacement, reducing equipment downtime.
Application Fields in Lithium Battery Industry
Cathode Material Dry Mixing: Mixing of lithium iron phosphate (LFP), lithium nickel cobalt manganese oxide (NCM), lithium nickel cobalt aluminum oxide (NCA) with conductive carbon black (e.g., Super P), conductive graphite, and binders (e.g., PVDF) for pre-dispersion before wetting.
Anode Material Dry Mixing: Uniform blending of artificial graphite, natural graphite, and additives (e.g., carbon nanotubes, SBR binders) to ensure consistent conductivity and binding performance of the anode sheet.
Auxiliary Material Preparation: Mixing of battery separator coating materials (e.g., Al₂O₃, SiO₂ dry powder) and conductive paste pre-mixes, ensuring stable particle size distribution for subsequent processes.
R&D & Pilot Testing: Small-capacity models (10 L-150 L) are ideal for formula optimization of new lithium battery materials (e.g., sodium-ion battery cathodes, silicon-based anodes), supporting rapid verification of material ratios.
