Atomfair-DPM-7219 Dual-Planet Dispersing Mixer
Product Overview
The Atomfair-DPM-7219 Dual-Planet Dispersing Mixer is a high-efficiency mixing equipment integrating dispersion and mixing functions, equipped with low-speed stirring components and high-speed dispersion components. The low-speed stirring components adopt planetary gear transmission, and the stirring paddles rotate on their own axes while revolving, driving materials to move up, down and around, thus achieving the ideal mixing effect in a short time.
Functional Features

- Variable frequency regulation for stirring motor: The stirring motor is equipped with a gearbox for variable frequency adjustment, allowing the selection of different rotation speeds and torques according to different processes and material viscosities.
- Double dispersion paddle design: The dual dispersion paddle structure drives materials to churn up, down and around, enabling rapid and uniform mixing of slurries.
- Compact overall dimensions: The equipment features a small footprint, effectively saving workshop space.
- Exquisite appearance: Adopting a solid geometric design, the equipment is concise and aesthetically pleasing with a refined finish.

The mixer requires a customer-supplied circulating cold and hot water source to maintain the operating temperature range of 7°C to 80°C, with a temperature measurement accuracy of ±2°C. The equipment must be operated within a static vacuum leakage rate of ≤15% over 12 hours to ensure process integrity.
- Temperature Control Requirement: The process temperature must be maintained between 7°C and 80°C using a customer-supplied circulating water system, as the mixer does not include an integrated heating or cooling mechanism.
- Vacuum Integrity Constraint: The static vacuum leakage rate must not exceed 15% within a 12-hour period to ensure consistent mixing conditions and prevent contamination.
- Material Viscosity and Solids Constraint: The mixer is designed for slurries with a viscosity range of 1,000 to 1,000,000 cP and a solid content of 30% to 80%, requiring the user to verify that the material falls within these parameters before operation.
- Paddle Clearance Tolerance: The paddle clearances are factory-set to 3–6 mm between paddles, 3–5 mm between paddle and barrel wall, and 2–4 mm between paddle and barrel bottom, and must not be altered to avoid mechanical failure.
This procedure outlines the safe and effective operation of the dual-planet dispersing mixer for preparing high-viscosity slurries. Follow the steps in sequence to ensure proper mixing and to avoid equipment damage.
Required Equipment: Atomfair-DPM-7219 Dual-Planet Dispersing Mixer, Circulating water bath (customer-supplied)
- Verify utility connections
Connect the customer-supplied circulating cold and hot water supply to the mixer's temperature control jacket and confirm the flow is active. - Set the operating temperature
Set the circulating water temperature to the desired process value within the 7°C to 80°C range and allow the system to stabilize. - Load the material
Transfer the pre-mixed slurry (viscosity 1,000–1,000,000 cP, solid content 30–80%) into the double-layer stainless steel barrel, ensuring the volume does not exceed the 5L effective capacity. - Position the mixing barrel
Secure the mixing barrel onto the machine platform and raise it until the stirring paddles and dispersion disc are fully immersed in the slurry. - Set the mixing parameters
Adjust the stirring paddle speed (0–98 rpm), revolution speed (0–43 rpm), and dispersion speed (0–6200 rpm) using the variable frequency drives to match the process requirements. - Start the mixing cycle
Start the mixer and run the mixing cycle for the required duration, monitoring the temperature and vacuum (if applicable) to ensure they remain within specified limits. - Stop and discharge
Stop the mixer, lower the barrel, and discharge the mixed slurry, then clean the paddles and barrel immediately to prevent material residue from hardening.
What is the maximum slurry viscosity and solid content the Atomfair-DPM-7219 Dual-Planet Dispersing Mixer can handle?
The Atomfair-DPM-7219 is designed to process slurries with a viscosity range of 1,000 to 1,000,000 cP and a solid content of 30% to 80%. This wide operating window makes it suitable for high-viscosity battery electrode slurries, such as those containing PVDF, CMC, and conductive agents, while maintaining effective mixing and dispersion.
What are the clearance tolerances between the stirring paddles and the mixing barrel, and why do they matter?
The Atomfair-DPM-7219 features precise clearances: 3–6 mm between paddles, 3–5 mm between paddle and barrel wall, and 2–4 mm between paddle and barrel bottom. These tight tolerances ensure efficient material turnover and minimize dead zones, which is critical for achieving uniform dispersion in high-viscosity battery slurries.
What are the utility and infrastructure requirements for operating the Atomfair-DPM-7219?
The mixer requires a customer-supplied circulating cold and hot water source to maintain the operating temperature range of 7°C to 80°C, with a temperature measurement accuracy of ±2°C. Additionally, the equipment is designed for vacuum operation, with a static vacuum leakage rate of ≤15% within 12 hours, so a vacuum pump and appropriate connections are necessary for full functionality.
The Atomfair-DPM-7219 Dual-Planet Dispersing Mixer integrates low-speed planetary stirring with high-speed dispersion (up to 6200 rpm) in a 5L effective volume, designed for battery slurries with viscosities up to 1,000,000 cP and solid contents of 30-80%. Its 304 stainless steel barrel and tight paddle clearances (2-6mm) support homogeneous mixing, but the unit requires external temperature control and vacuum infrastructure to meet the stated performance and leakage specifications.
Positive
- Dual dispersion and planetary mixing: Combines low-speed planetary stirring (0-98 rpm) with high-speed dispersion (0-6200 rpm, linear speed 0-20 m/s) to achieve rapid, uniform slurry mixing, as stated for battery materials like PVDF, CMC, and lithium iron phosphate.
- High-viscosity and solid-load capability: Handles slurries with viscosity from 1,000 to 1,000,000 cP and solid content of 30-80%, with a stirring paddle effective load of ≥3 Nm/cm², supporting demanding electrode slurry formulations.
Trade-offs
- Requires external temperature control: Operating temperature range of 7°C to 80°C and temperature measurement accuracy of ±2°C depend on customer-supplied circulating cold and hot water, adding infrastructure and utility requirements.
- Vacuum leakage rate constraint: Static vacuum leakage rate is specified at ≤15% within 12 hours, which may not meet stringent vacuum integrity requirements for moisture-sensitive battery processes without additional sealing measures.
