15L Vacuum Double Planetary Mixer for Silicone Sealant – SXJ Series, Engineered for the Philippine Market
For silicone sealant manufacturers, achieving a smooth, fully deaerated, and uniformly dispersed product is critical. This 15L working capacity vacuum planetary mixer machine belongs to our SXJ series and is purpose-built for customers in the Philippines who require a reliable industrial vacuum mixer that delivers both gentle kneading and high-shear dispersion. The design directly references proven laboratory double planetary mixers, combining robust specifications—2.2 kW drives, electric lifting, and vacuum capability down to ≤ -0.098 MPa—into a compact, production-ready system.
Whether you are scaling up from a 2L laboratory planetary vacuum mixer for li-ion battery slurry mixing, evaluating a 5 litre lab planetary vacuum mixer machine, or searching for a planetary mixer second hand or used planetary mixer to begin production, the SXJ-15 delivers repeatable, bubble-free results. It is a true vacuum double planetary mixer, not a small centrifugal-only device like a thinky planetary vacuum mixer or an arv-310 vacuum planetary centrifugal mixer. If you have been comparing arv-310 arv-310 vacuum planetary centrifugal mixer cost against actual throughput, a 15L working capacity double planetary system offers far greater value once batch sizes grow beyond a few hundred grams.

Machine Structure
The SXJ-15-PH is constructed for durability, cleanliness, and ease of operation. Every structural element reflects the specifications of the SXJ series.
Mixing Vessel – A 24-liter design volume stainless steel bowl with polished inner walls and an integrated jacket for temperature control.
Double Planetary Paddles – Two frame-type paddles mounted on a revolving carrier. The 2.2 kW drive provides revolution speeds from 0 to 43 rpm and self-rotation from 0 to 99 rpm, continuously kneading the product and scraping the vessel wall.
High-Speed Disperser – An independent 2.2 kW shaft with a dispersion disc, running up to 2980 rpm. This turns the unit into a compact dual-shaft planetary vacuum mixer, ideal for breaking down filler agglomerates in silicone sealants.
Vacuum Chamber and Lid – A rigid, sealed lid connected to a vacuum pump capable of ≤ -0.098 MPa. The sealing system ensures stable vacuum holding throughout the mixing cycle.
Electric Lifting System – The mixing head and lid assembly are raised and lowered by a reliable electric lift, providing easy access for vessel loading, cleaning, and product discharge.
Control Panel – Centralized push-button station for paddle speeds, disperser, vacuum, and lift. An optional PLC with HMI touch screen enables multi-step programming and data recording.
This layout makes the SXJ-15 a genuine China compact dual-shaft planetary vacuum mixer when the disperser is engaged, or a pure double planetary vacuum mixer in its standard configuration.
Working Principle
The operating principle of this vacuum planetary mixer follows the same double planetary action proven in laboratory and production environments:
Planetary Kneading – The paddles self-rotate and revolve, continuously folding and shearing the silicone sealant. The specified speed ranges (0-43 rpm revolution, 0-99 rpm self-rotation) ensure uniform distribution of fillers and additives without dead zones.
Vacuum Degassing – The vacuum pump pulls the vessel to deep vacuum, expanding and evacuating entrapped air. This integrated step makes the SXJ-15 a highly effective planetary vacuum defoaming mixing machine, producing a dense, bubble-free paste ready for filling.
High-Shear Dispersion – The independent disperser runs at up to 2980 rpm, breaking down agglomerates of fumed silica, calcium carbonate, and other fillers while the planetary paddles keep the bulk mass moving. The result is a smooth, glossy sealant without the need for separate dispersion equipment.
Discharge – After the cycle, the vacuum is released, and the electric lift raises the lid and paddle assembly. The vessel can be moved or tilted for clean material transfer.
Because the SXJ-15 is part of a fully scalable series, parameters established on smaller lab units—like a 2L laboratory planetary vacuum mixer for li-ion battery slurry mixing or a 5 litre lab planetary vacuum mixer machine—transfer directly to this 15L production platform.
Application Cases
The SXJ-15-PH handles a wide range of high-viscosity materials required by Philippine manufacturers:
Silicone Sealants – Neutral, acetoxy, and oxime-cure construction sealants. The dual-shaft mixing achieves thorough filler wetting and complete air removal for smooth extrusion.
Electronic Potting and Encapsulation – Epoxy and silicone compounds for component protection, where void-free dispensing is essential.
Thermal Interface Materials – Conductive greases and pastes uniformly blended without degrading filler structure.
Adhesives and Mastics – Polyurethane, MS polymer, and butyl-based products that require intensive kneading and vacuum degassing.
Cosmetic and Pharmaceutical Pastes – Thick creams and gels processed under vacuum for a lump-free, air-free texture.
For customers who need to test formulations before investing in a full-scale machine, we also offer smaller capacity planetary vacuum mixer options, including a 5 litre planetary vacuum mixer for solid state battery research or a compact dual-shaft planetary vacuum mixer with a 150 ml container. We can also help source a planetary mixer second hand or used planetary mixer for budget-conscious projects.
