Double planetary mixer

A high-performance mixer must feature dual agitator blades that rotate on their own axes while simultaneously revolving around a central axis. Ensure the unit includes high-precision gears to maintain a clearance of 2mm to 5mm between the blades and the tank wall, which prevents material dead zones. Additionally, look for vacuum-tight sealing (up to -0.098Mpa) to eliminate bubbles in high-viscosity pastes and PLC-controlled frequency conversion for precise speed adjustment.

Capacity should be selected based on your batch cycle time and daily output targets, typically ranging from 5L for R&D to 2000L for mass production. Power requirements are critical; high-viscosity materials (over 1,000,000 cps) require high-torque motors with reinforced transmission systems. Always verify the motor brand (e.g., Siemens or ABB) and the reduction gear ratio to ensure the machine can handle the resistance of thick slurries without overheating.

For lithium battery or chemical industries, the contact parts must be made of SUS304 or SUS316L stainless steel to prevent corrosion and contamination. If handling abrasive materials, a tungsten carbide or ceramic coating on the blades is recommended. Ensure the equipment complies with CE marking for safety, ISO 9001 for manufacturing quality, and Ex-proof (ATEX) certification if the mixing process involves volatile solvents.

These mixers are the industry standard for high-viscosity mixing (up to 2,000,000 cps). Primary scenarios include Lithium-ion battery slurry preparation, silicone sealants, electronic solder pastes, dental resins, and structural adhesives. They are also used in the pharmaceutical industry for thick ointments and gels where uniform dispersion of active ingredients is vital.

Request a Factory Acceptance Test (FAT) via video link or hire a third-party inspector to verify the blade-to-wall clearance and vacuum pressure retention before final payment. On Made-in-China.com, prioritize Audited Suppliers who provide comprehensive inspection reports and material certificates (MTC) to ensure the steel grade matches your order.

Focus on the Total Cost of Ownership (TCO) rather than just the sticker price. Negotiate for extended warranties (18-24 months) and the inclusion of critical wear parts (seals, gaskets, and bearings) for the first two years of operation. For large orders, propose a milestone-based payment structure (e.g., 30% deposit, 60% after successful FAT, 10% after arrival/installation).

Double Planetary Mixers are heavy and precision-aligned; they must be shipped in seaworthy wooden crates (IPPC standard) with anti-rust coating applied to exposed metal. Ensure the supplier uses internal bracing to prevent the mixing head from shifting during transit. For oversized units, confirm if Flat Rack containers are required and verify the Incoterms (FOB or CIF) to clarify insurance responsibilities.

Utilize Secured Trading services on Made-in-China.com to protect your funds until shipping documents are verified. Regarding after-sales, confirm the supplier's ability to provide remote technical support via video call and check if they have a global DHL/FedEx account for rapid dispatch of replacement parts. Always ask for an English-language operation manual and electrical schematics.
