Battery Material Mixer Machine
Planetary Mixers & Ribbon Blenders for Lithium Battery Electrode Slurry and Powder Processing
Two Key Mixing Stages in Battery Manufacturing
Battery electrode production involves two distinct mixing processes, each requiring different equipment and process conditions:
Electrode Slurry Mixing
Active materials (NMC, LFP, NCA, graphite), conductive additives (carbon black), binders (PVDF, CMC/SBR), and solvent (NMP or water) are mixed together to form a homogeneous electrode slurry. This slurry is then coated onto aluminum foil (cathode) or copper foil (anode), dried, and calendered to form battery electrodes.
Equipment required: Planetary mixer with vacuum degassing and temperature control
Electrode Powder Premixing
Before slurry preparation, cathode and anode active material powders — including LFP, NMC, NCA, graphite, and carbon black — are pre-blended in dry form to ensure uniform distribution of particles and conductive agents. Uniform powder premixing reduces agglomeration and improves the consistency of the final slurry.
Equipment required: Horizontal ribbon blender for gentle, uniform dry powder mixing
Battery Materials Processed by LRMIX Equipment
LRMIX mixing equipment is used across cathode, anode, and electrolyte material processing in lithium-ion battery production:
Recommended Equipment for Battery Material Processing
LRMIX offers two complementary machines that cover both wet and dry battery material processing stages:
Planetary Mixer — Electrode Slurry
The planetary mixer is the industry-standard equipment for battery electrode slurry production. Its dual planetary mixing action — blades that rotate on their own axes while simultaneously orbiting the mixing vessel — ensures complete, homogeneous dispersion with no dead zones. Vacuum degassing removes trapped air bubbles that would otherwise compromise electrode coating quality.
- Capacity: 1L (lab) to 2000L (production)
- Paddle, twist, claw and frame blade options
- Vacuum system for full degassing
- Heating & cooling jacket for temperature control
- Variable speed drive for precise shear control
- Suitable for NMC, LFP, NCA, graphite slurries
- Multi-shaft configurations available
Ribbon Blender — Dry Powder Mixing
The horizontal ribbon blender is used for pre-blending dry cathode and anode powders before wet slurry preparation. Its inner and outer helical ribbon agitators create a counter-current mixing action that gently and uniformly blends active materials, conductive additives, and dry binders — minimizing particle damage and ensuring consistent batch-to-batch composition.
- Capacity: 50L to 10,000L
- Double helical ribbon agitator design
- Gentle mixing with minimal particle breakage
- Uniform distribution of carbon black and PVDF
- SS304 or SS316L contact surface options
- Easy cleaning and full discharge
- Suitable for LFP, NMC, graphite powder blending
