Vacuum Double Planetary Mixer with Heating Jacket

What is the Vacuum Double Planetary Mixer with Heating Jacket?

A vacuum double planetary mixer with a heating jacket combines planetary kneading, vacuum degassing and controlled temperature in a sealed bowl. It is used for battery slurries, silicone, adhesives and pharmaceutical bases that need heat and void-free mixing.

Overview

This variant seals the bowl with a vacuum lid and adds a jacket through which oil or water circulates for heating or cooling. Vacuum levels down to about 0.1 kPa absolute remove air, moisture and volatiles while the blades knead the batch. Temperature range is usually ambient to 150 or 200 degrees C with an external thermostat, and cooling is possible with chilled water. Working volume is 2 to 100 L, with orbit speeds of 5 to 50 rpm and optional high-speed disperser up to 3,000 rpm. Sensors log temperature, pressure and torque. Seals, shaft glands and lid fittings are specified for vacuum and heat, and contact surfaces are polished stainless steel. This design is chosen for lithium-ion electrode slurries, silicone rubber, thermal pastes, pharmaceutical ointment bases and other products where viscosity depends on temperature.

How does it work?

A planetary mixer moves the mixing element in a planetary pattern: it rotates about its own axis while also orbiting around the vessel center, like a planet around the sun. In double planetary mixers, two blades orbit and rotate inside a stationary bowl, sweeping the full volume and wall, which gives thorough blending of high-viscosity materials up to several hundred thousand mPa·s. In planetary centrifugal mixers, a sealed container is spun on an orbital arm while also rotating in the opposite direction, so centrifugal force mixes and removes air without a blade. Vacuum options lower pressure to remove entrapped bubbles. Key components include the drive motor and gearbox, the blades or container holder, a bowl with optional jacket, a lid, speed control and, where fitted, a vacuum pump and heating or cooling system.

What are the key features?

• Vacuum down to about 0.1 kPa with sealed lid and shaft glands
• Jacketed bowl for heating with oil or cooling with water
• Temperature up to 150–200 °C controlled by external thermostat
• Optional high-speed disperser up to 3,000 rpm
• Data logging of temperature, pressure and torque
• Polished stainless steel contact surfaces for easy cleaning

What are the technical specifications?

A typical vacuum double planetary mixer with heating jacket configuration offers working volume of 2–100 L, orbit speed of 5–50 rpm, disperser speed of Up to 3,000 rpm (optional), vacuum level of 0.1–5 kPa absolute, temperature range of Ambient to 150–200 °C and jacket medium of Thermal oil or water. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Vacuum Double Planetary Mixer with Heating Jacket is used in lithium-ion electrode slurry, silicone rubber compounding, thermal paste preparation, pharmaceutical ointment base and hot-melt adhesive development. Across the wider Planetary Mixers class, laboratories also deploy it for lithium-ion battery slurry preparation, adhesive and sealant mixing and cosmetic cream and gel formulation.

Which standards and certifications apply?

Relevant standards and methods include IEC 61010-1, EN ISO 12100, ISO 3219, ASTM D2196 and GB/T 15706. Certification candidates for this model are CE, RoHS and ISO 9001 manufacturing; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Install the mixer on a rigid, level floor or bench sized for its weight and vibration. Verify power supply and cooling water or compressed air needs before delivery. Balance containers precisely in planetary centrifugal models, because imbalance causes vibration and bearing wear. Inspect seals and O-rings on vacuum models and clean blades, bowl and lid between batches to avoid cross-contamination. Use materials compatible with solvents, acids or abrasive fillers. Fit guards and interlocks that stop the drive when the lid or safety cover is opened, in line with IEC 61010-1 and machinery safety practice. Keep a maintenance log for gearbox oil, seals and calibration of speed and temperature sensors.

How do I select the right Vacuum Double Planetary Mixer with Heating Jacket?

Choose this variant when a formulation needs heat or cooling together with vacuum degassing. A non-jacketed mixer is sufficient for ambient work. In the RFQ, specify working volume, temperature range, vacuum level, viscosity, contact materials and data logging requirements.

How does it compare with other Planetary Mixers variants?

Start with the viscosity range and batch size. Planetary centrifugal mixers handle small batches from a few grams to about 2 kg and are quick, with no blade to clean and minimal contamination. Double planetary mixers handle working volumes from 1 L to 100 L or more and are preferred for very high viscosity pastes and slurries. Decide whether vacuum is required for degassing, for example in battery electrodes, silicone and epoxy. Specify heating or cooling needs through a jacketed bowl, plus material compatibility such as stainless steel 316L or ceramic coatings. Check speed range, torque and whether variable orbit and rotation ratios are available. For regulated products, consider cleanability, contact materials and documentation. Safety interlocks and explosion-proof options matter where flammable solvents are used.
